Add to @plugins/ddd/rules/ new rule `avoid-code-duplication`, use @plugins/customaize-agent/skills/create-rule/SKILL.md as instructions for creating the rule. This rule should include function dublication example, but not only this. It should focus more on concepts and logic duplication, and include examples for it.

Add to @plugins/ddd/rules/ new rule `boy-scout-rule`, use @plugins/customaize-agent/skills/create-rule/SKILL.md as instructions for creating the rule. This rule should cover the concept of "boy scout rule", which is a rule that force agent to allways leave the code better than they found it, when they touch it, by refactoring and improving it. This rule should include examples of how to properly do it, and how to avoid over-engineering and too much refactoring. Research principles and practices that can be quoted, instead of writing own version of it. +3. Add or update @plugins/sdd/agents/code-explorer.md new section to search for code/functions/logic/concepts that can be reused during implementation of the task. Include specific section in scratchpad template and add examples at the end of the agent file. +4. Update @plugins/sdd/agents/software-architect.md specific requirement to use reusable code/functions/logic/concepts when possible from codebase impact analysis during planing and include it as requirement for implementation of the task. Update strachpad template with it, and add examples at the end of the agent file. +5. Update @plugins/sdd/agents/qa-engineer.md to include regular checks section for each step. Specifically, agent should analyse what quality gates are avaiable, like build,lint,test,etc. And include in step requirements checklist that build/lint/test/... should pass, each as separate item. Also, in this regular checks section should be included check that newly written code not have any code dublication, and that it allign with CLAUDE.md/CONTRIBUTING.md/rules/etc (depending on what avaiable) and that it followed boy scout rule. And if software architecture plan mention any code/functions/logic/concepts that can be reused in this step, qa should include check that this code/functions/logic/concepts was used in the step. +6. Create new agent in @plugins/sdd/agents/ directory, name it `code-quality-reviewer`. This agent should be responsible for reviewing the code quality of the codebase, focusing on newly written code, but also checking that align with rest of codebase, project guidelines, style guides, and best practices, and that it reused all possible code/functions/logic/concepts from what existin in codebase. And include call of it in @plugins/sdd/skills/implement/SKILL.md file. It should become part of Phase 3: Final Verification and be spawned in parallel with judge agent. Code Quality Reviewer should provide very strict review of all newly written code using checks and scoring rubrics and return score and list of found issues. Then if score is below 3/5, orcestrator should launch developer agent to fix issues and then again code-quality-reviewer agent to verify. Orcestrator should iterate up to 3 times, until score will pass. In order to write code-quality-reviewer.md follow this process: +- Copy paste @plugins/sadd/agents/judge.md file to it and rename it to code-quality-reviewer.md. Modify there role, goal and anything that not align with code quality reviewer role. +- The default judge agent expect that it will receive yaml for checklist/scoring rubrics/etc. Write this yaml and include directly in code-quality-reviewer.md and update code-quality-reviewer.md to use this yaml instead of expecting it from user. In order to write yaml PRECISELY follow @plugins/sadd/agents/meta-judge.md. And use @plugins/ddd/rules/ files as basis for checks and scoring rubrics. Each of the rules should be presented in at least one checklist item or scoring rubric. +- Analyse Muda (Waste Analysis) method from @plugins/kaizen/skills/analyse/SKILL.md and include it as separate stage in code-quality-reviewer.md. Include exampels and all types of waste, update scratchbook templatae to include this stage properly. Code Quality Reviewer should follow this stage preciasly and report all found issues using it. And for each found issue, he should decrease final score, based on the impact of the issue. +7. Update @plugins/sdd/skills/implement/SKILL.md to add param `--skip-code-quality-review` to skip code quality review and `--code-quality-review-score` to set the score threshold for code quality review (default is 3/5). \ No newline at end of file From fb908730753e432f8970603b700dcd9bdbfd85df Mon Sep 17 00:00:00 2001 From: leovs09 Date: Sun, 3 May 2026 23:02:26 +0200 Subject: [PATCH 02/11] spec: add draft of internal templating support tool --- ...dd-template-markdown-generation.feature.md | 71 +++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 .specs/tasks/draft/add-template-markdown-generation.feature.md diff --git a/.specs/tasks/draft/add-template-markdown-generation.feature.md b/.specs/tasks/draft/add-template-markdown-generation.feature.md new file mode 100644 index 0000000..ce979f3 --- /dev/null +++ b/.specs/tasks/draft/add-template-markdown-generation.feature.md @@ -0,0 +1,71 @@ +--- +title: Add template-based markdown file generation and manipulation +--- + +## Initial User Prompt + +add template based markdown files generation and manipulation + +### Acceptance Criteria + +This project need cli tool which is capable of performing following operations: +- extracting structure of a markdown file (all headers and frontmatter) and displaying it in a tree like structure + - it should also show amount of lines and tokens (approximatly) in the file and per each section + - it should show list items amount +- extract and show only specific sections content of the file.

MEDIUM: Add automated rollback capability +6. MEDIUM: Make security scan blocking +``` + +### STAGE 2: Generate Reference Expectations + +CRITICAL: Before examining the code in detail, you MUST outline what a high-quality implementation would look like. Use extended thinking / reasoning to draft what a correct, high-quality artifact must contain to fulfill the requirements. + +1. What patterns and existing code SHOULD be reused? +2. What architectural boundaries MUST be respected? +3. What naming conventions the codebase follows? +4. What size limits apply? +5. Common mistakes for this type of change? + +Do NOT write a complete implementation. Outline the critical elements, decisions, and quality markers that a correct artifact would exhibit. + +### STAGE 3: Comparative Analysis + +Now compare the agent's artifact against your reference expectations result: + +1. **Identify matches**: Where does the artifact align with your reference? +2. **Identify gaps**: What did the agent miss that your reference includes? +3. **Identify deviations**: Where does the artifact diverge from your reference? Is the deviation justified or problematic? +4. **Identify additions**: Did the agent include something your reference did not? Is it valuable or noise? +5. **Identify mistakes**: Are there factual errors, inaccurate results, or incorrect implementations? + +Document each finding with specific evidence: file paths, line numbers, exact quotes. + +### STAGE 4: Checklist Evaluation + +Apply each checklist item as a boolean YES/NO judgment. + +**Strictness rules**: YES requires the response to entirely fulfill the condition with no minor inaccuracies. Even minor inaccuracies exclude a YES rating. NO is used if the response fails to meet requirements or provides no relevant evidence, or you are not sure about the answer. + +For EACH checklist item in the evaluation specification: + +1. Read the `question` field +2. Search the artifact for evidence that answers the question +3. Answer YES or NO with a brief evidence citation +4. Note the `importance` level (essential, important, optional, pitfall) + +**Checklist output format:** + +```yaml +checklist_results: + - question: "[From specification]" + importance: "essential" + answer: "YES | NO" + evidence: "[Specific evidence supporting the answer]" +``` + +**Essential items that are NO trigger an automatic score review.** If any essential checklist item fails, the overall score cannot exceed 1.0 regardless of rubric scores. + +**Pitfall items that are YES indicate a quality problem.** Pitfall items are anti-patterns; a YES answer means the artifact exhibits the anti-pattern and should reduce the score. + + +### STAGE 5: Rubric Evaluation + +#### Chain-of-Thought Required + +For EVERY rubric dimension, you MUST follow this exact sequence: + +1. Find specific evidence in the work FIRST (quote or cite exact locations, file paths, line numbers) +2. **Actively search for what's WRONG** - not what's right +3. Explain how evidence maps to the rubric level +4. THEN assign the score +5. Suggest one specific, actionable improvement + +**CRITICAL**: +- Provide justification BEFORE the score. This is mandatory. **Never score first and justify later.** +- Evaluate each dimension as an isolated judgment. Do not let your assessment of one dimension influence another. +- Apply each rubric dimension independently using Chain-of-Thought evaluation steps. For each dimension, generate interpretable reasoning steps BEFORE scoring. This approach improves scoring stability and debuggability — the reasoning chain serves as an audit trail for every score assigned. + +For EACH rubric dimension in the evaluation specification: + +#### 5.1 Evidence Collection (Branch) + +Follow the `instruction` field from the rubric dimension. Search the artifact for specific, quotable evidence relevant to this dimension. Record: + +- What you found (with file:line references) +- What you expected but did NOT find +- Results of any practical verification (lint, build, test commands) + +#### 5.2 Score Assignment (Solve) + +Apply the `score_definitions` from the specification. Walk through each score level (1 through 5) and determine which definition best matches your evidence. + +**MANDATORY scoring rules (aligned with scoring scale):** +- **Score 1 (Below Average):** Basic requirements met but with minor issues. Common for first attempts. +- **Score 2 (Adequate — DEFAULT):** Meets ALL requirements AND there is specific evidence for each requirement being met. This is refined work. You MUST justify any score above 2. +- **Score 3 (Rare):** All done exactly as required, there no gaps or issues. Genuinely solid or almost ideal work. +- **Score 4 (Excellent):** Genuinely exemplary — there is evidence that it is impossible to do better within the scope. Less than 5% of evaluations. +- **Score 5 (Overly Perfect):** Exceeds requirements, done much more than what was required. **Less than 1% of evaluations.** If you are giving 5s, you are almost certainly too lenient. + +CRITICAL: +- **Ambiguous evidence = lower score.** Ambiguity is the implementer's fault, not yours. +- **Default score is 2 (Adequate).** Start at 2 and justify any movement up or down with specific evidence. +- **Provide the reasoning chain FIRST, then state the score.** Write your analysis of how the evidence maps to the score definitions, THEN conclude with the score number. + +#### 5.3 Structured Output Per Dimension + +```yaml +- criterion_name: "[Dimension Name]" + weight: 0.XX + evidence: + found: + - "[Specific evidence with file:line reference]" + missing: + - "[What was expected but not found]" + verification: + - "[Results of practical checks if applicable]" + reasoning: | + [How evidence maps to score definitions. Reference the specific + score_definition text from the specification that matches.] + score: X + weighted_score: X.XX + improvement: "[One specific, actionable improvement suggestion]" +``` + +### STAGE 6: Muda Waste Analysis + +**This is a SEPARATE evaluation stage.** Apply the 7 types of waste from Lean/Kaizen methodology to the newly written code. For each waste type found, document the instance and decrease the final score based on impact. + +Examine the code for each waste type: + +**1. Overproduction** -- Building more than needed +- Features or code paths no one asked for +- Overly complex solutions for simple problems +- Premature optimization or unnecessary abstractions +- Speculative generality ("might need this later") + +**2. Waiting** -- Code that causes idle time +- Missing async/parallel execution where possible +- Synchronous operations that could be concurrent +- Unnecessary sequential dependencies + +**3. Transportation** -- Moving data around unnecessarily +- Excessive data transformations between layers +- Unnecessary serialization/deserialization cycles +- API layers that add no value (pass-through wrappers) +- Redundant data mapping between identical shapes + +**4. Over-processing** -- Doing more than necessary +- Excessive validation of already-validated data +- Redundant null checks on non-nullable types +- Overly verbose logging in production paths +- Unnecessary computation or data fetching + +**5. Inventory** -- Accumulated unfinished work +- Dead code, commented-out code, TODO comments without tracking +- Unused imports, unused variables, unused parameters +- Half-implemented features or abandoned code paths + +**6. Motion** -- Unnecessary movement or context switching +- Functions that require reading multiple files to understand +- Circular dependencies between modules +- Code organized by technical layer rather than feature/domain +- Configurations scattered across many files + +**7. Defects** -- Code likely to produce bugs +- Missing error handling for external calls +- Race conditions in async code +- Implicit type coercions +- Missing boundary checks or input validation + +**Waste Impact Scoring:** + +| Impact Level | Score Reduction | Criteria | +|---|---|---| +| Critical | -0.50 | Waste directly causes bugs, data loss, or system failures | +| High | -0.25 | Waste significantly degrades maintainability or performance | +| Medium | -0.10 | Waste creates unnecessary complexity or maintenance burden | +| Low | -0.05 | Waste is minor inefficiency with minimal practical impact | + +#### Process + +1. **Define scope**: Codebase area or process +2. **Examine for each waste type** +3. **Quantify impact** (time, complexity, cost) +4. **Prioritize by impact** +5. **Propose elimination strategies** + +#### Example: API Codebase Waste Analysis + +``` +SCOPE: REST API backend (50K LOC) + +1.

Equivalence Partitioning (EP) + +Divide input domain into partitions where the system is expected to behave the same way; ONE test per partition is sufficient. + +**Worked example** — `discount(orderTotal: number) -> number`: + +| Partition | Range | Representative test input | Expected | +|-----------|-------|---------------------------|----------| +| Below threshold | `0 <= total < 100` | `50` | `0% discount` | +| Mid tier | `100 <= total < 500` | `250` | `5% discount` | +| Top tier | `total >= 500` | `1000` | `10% discount` | +| Invalid (negative) | `total < 0` | `-1` | `throw / error` | + +Four tests cover all partitions. EP alone misses boundaries — combine with BVA. + +### 2. Boundary Value Analysis (BVA) + +Bugs cluster at boundaries. For every boundary value `B`, test **`B-1`, `B`, `B+1`** (or for floats, the smallest representable step). + +**Worked example** — same `discount` function, boundary at `100`: + +| Test input | Why | Expected | +|------------|-----|----------| +| `99` (= B-1) | Last value of "below threshold" partition | `0% discount` | +| `100` (= B) | First value of "mid tier" partition | `5% discount` | +| `101` (= B+1) | Confirms not off-by-two | `5% discount` | + +Repeat for boundary at `500`: test `499`, `500`, `501`. Total: 6 boundary tests + 4 EP tests = 10 cases. + +The `B-1 / B / B+1` triplet has the same shape across boundaries (vary input, vary expected output, identical assertion); this is a natural fit for a **table-driven test** (see sub-section 5 below). + +### 3. Decision Tables + +When output depends on combinations of conditions. Each column is a rule. + +**Worked example** — `canCheckout(cartHasItems, paymentValid, addressOnFile)`: + +| Condition / Rule | R1 | R2 | R3 | R4 | +|------------------|----|----|----|----| +| cartHasItems | T | T | T | F | +| paymentValid | T | T | F | * | +| addressOnFile | T | F | * | * | +| **Result** | allow | block:address | block:payment | block:cart | + +Four tests, one per rule (`*` = don't care, dropped via merging). + +### 4. State Transition + +When behavior depends on history. Identify states, events, and forbidden transitions. + +**Worked example** — Order state machine with states `{draft, submitted, paid, shipped, cancelled}`: + +| From | Event | To | Test | +|------|-------|----|----| +| draft | submit | submitted | happy path | +| submitted | pay | paid | happy path | +| paid | ship | shipped | happy path | +| draft | cancel | cancelled | early cancel | +| paid | cancel | reject | forbidden — refund flow required, NOT direct cancel | +| shipped | submit | reject | forbidden | + +Cover one test per legal transition + one per forbidden transition (negative path). + +### 5. Table-Driven Tests + +When EP, BVA, or decision-table analysis yields **3+ cases with the same shape** (same setup, same assertion, only inputs and expected outputs differ — e.g., parsing valid/invalid date formats; computing tax across brackets; routing rules) collapse them into a single **table-driven test**. The cases become rows in a data table; the test body iterates the rows and runs one assertion per row. References: Dave Cheney, [Prefer table-driven tests](https://dave.cheney.net/2019/05/07/prefer-table-driven-tests); [Go wiki: TableDrivenTests](https://go.dev/wiki/TableDrivenTests). + +Do **NOT** force a table when setup, framework calls, or the assertion shape varies substantially across cases. Forced uniformity hides real differences behind a single name and produces obscure failure messages — keep those as separate, individually named tests. + +**Worked example** — six EP+BVA cases for `discount(orderTotal)` (boundary at `100`) collapsed into one table-driven unit test (TS / vitest syntax; the same pattern applies to Go `t.Run`, JUnit `@ParameterizedTest`, pytest `parametrize`): + +```ts +describe("discount", () => { + const cases: Array<{ name: string; input: number; expected: number }> = [ + { name: "EP: below threshold (typical)", input: 50, expected: 0 }, + { name: "BVA: B-1 at boundary 100", input: 99, expected: 0 }, + { name: "BVA: B at boundary 100", input: 100, expected: 0.05 }, + { name: "BVA: B+1 at boundary 100", input: 101, expected: 0.05 }, + { name: "EP: mid tier (typical)", input: 250, expected: 0.05 }, + { name: "EP: top tier (typical)", input: 1000, expected: 0.10 }, + ]; + + for (const c of cases) { + it(c.name, () => { + expect(discount(c.input)).toBe(c.expected); + }); + } +}); +``` + +The `name` column is mandatory: each row must produce an individually addressable test so failures point to the specific case, not "row 3 of 6". Rows that need a different assertion (e.g., the negative-input case throws) stay as separate tests outside the table. + +--- + +## Dependency Decision + +For Gate 2 (Integration) and Gate 3 (Component/E2E), choose dependencies deliberately. The goal is **maximum realism that still runs deterministically in CI**. + +| Dependency style | Use when | Avoid when | Notes | +|------------------|----------|------------|-------| +| **Real infra via [Testcontainers](https://testcontainers.com/)** | DB/Redis/Kafka/Browser, dev needs real driver behavior, hermetic CI required | Cold-start budget < 1s, no Docker available | Default for integration tests on Postgres / Redis / Kafka / Localstack | +| **In-memory fake** | Owned interface, semantics are simple (key-value, list), test speed critical | Fake diverges from real — silent bugs at integration boundary | Acceptable for repository ports in hexagonal architectures, IF the port has its own contract test against real infra | +| **Mock (test double)** | Single collaborator with pure interface; test focuses on protocol (was X called with Y) | You're mocking >2 collaborators or mocking data structures (anti-pattern: incomplete mocks) | Mocks are tools to isolate, not things to test | +| **Stubbed HTTP** | Calling external SaaS where Testcontainers / Localstack option doesn't exist | When Pact / CDC is needed (use contract tests instead) | nock (Node), responses (Python), WireMock (JVM) | +| **Real external service** | Smoke test in staging only | Unit / integration / CI — always non-deterministic | Reserve for smoke tests against staging | + +**Tradeoff summary**: Testcontainers > in-memory fake > mock, but cost goes the same direction.

When domain logic is coupled to controllers, ORMs, or HTTP libraries, it becomes untestable in isolation, impossible to reuse across delivery mechanisms, and fragile to infrastructure changes. Define domain entities that model business rules with no imports from framework or database packages. Implement use cases as classes that depend on abstract repository interfaces, not concrete database clients. Let the infrastructure layer implement those interfaces and inject them at composition time. This dependency inversion ensures the domain drives the architecture rather than the framework dictating how business rules are organized. + +#### Critical Clean Architecture & DDD Principles + +- Separate domain entities from infrastructure concerns +- Keep business logic independent of frameworks +- Define use cases clearly and keep them isolated +- Avoid code duplication through creation of reusable functions and modules + +#### Incorrect + +Business logic is embedded directly in the HTTP handler, coupled to the web framework and database client.

These names attract unrelated functions, creating grab-bag files with no cohesion.

Deeply nested code (more than 3 levels) increases cognitive load, obscures the happy path, and makes functions harder to read, review, and maintain. When guard clauses are placed first, the main logic stays at the top indentation level and reads linearly from top to bottom. + +#### Incorrect + +Validation checks are nested inside each other, pushing the core business logic deep into indentation. The happy path is buried at the innermost level, and error handling is scattered across multiple `else` branches at the bottom. + +```typescript +async function validateUser(userId: string, role: string): Promise { + if (userId) { + const user = await db.users.findById(userId) + if (user) { + if (!user.isDeleted) { + if (user.role === role) { + if (user.emailVerified) { + // happy path buried 5 levels deep + return user + } else { + throw new Error('Email not verified') + } + } else { + throw new Error('Insufficient role') + } + } else { + throw new Error('User is deleted') + } + } else { + throw new Error('User not found') + } + } else { + throw new Error('User ID is required') + } +} +``` + +#### Correct + +Guard clauses handle each error condition with an early return at the top level. The happy path flows naturally at the end of the function with zero unnecessary nesting. + +```typescript +async function validateUser(userId: string, role: string): Promise { + if (!userId) + throw new Error('User ID is required') + + const user = await db.users.findById(userId) + if (!user) + throw new Error('User not found') + if (user.isDeleted) + throw new Error('User is deleted') + if (user.role !== role) + throw new Error('Insufficient role') + if (!user.emailVerified) + throw new Error('Email not verified') + + return user +} +``` + + +### Explicit Control Flow and Policy-Mechanism Separation + +Error conditions, branching, and control flow decisions must be visible at the call site — never hidden inside helper functions that look like simple validators or utilities. This is an application of the policy-mechanism separation principle: a "mechanism" is a pure function that computes a result and returns it; a "policy" is what the caller decides to do with that result — throw, log, branch, or ignore. + +When policy is hidden inside mechanism (e.g., a `validate` function that throws instead of returning a boolean), the call site becomes deceptive. The reader sees what looks like a passive check but is actually a control flow branch that can halt execution. Keeping mechanisms pure and policies explicit at the call site makes code predictable and composable: the same mechanism can serve different policies without modification. + +Apply this separation consistently: + +- **Mechanism** = `isValid(result)` returns a boolean. **Policy** = the caller decides to throw. +- **Mechanism** = `applyNewFeature(baseData)` returns new data. **Policy** = the caller decides whether to call it based on a feature flag. +- **Mechanism** = `formatResult(result)` returns a string. **Policy** = the caller decides to log it. + +#### Incorrect + +`validateResult` hides a throw inside what reads like a passive validation check. The call site shows no branching, no `if`, no `throw` — the reader assumes execution continues normally after the call. The control flow decision (throw on invalid) is buried inside the mechanism. + +```typescript +function validateResult(result: Result): void { + if (!result.success) + throw new ProcessingError(result.error) + if (result.value < 0) + throw new RangeError("Negative value") +} + +// call site — looks harmless, hides two possible throws +const result = performProcess(param) +validateResult(result) +``` + +Similarly, hiding a feature-flag policy inside the mechanism couples the feature decision to the transformation: + +```typescript +function applyNewFeature(data: Data): Data { + if (!featureFlags.isEnabled("new-feature")) + return data // policy hidden inside mechanism + return transform(data) +} + +// call site — reader cannot tell a feature flag is being checked +const output = applyNewFeature(baseData) +``` + +#### Correct + +The mechanism (`isValid`) is a pure function that returns a value. The policy (what to do when invalid) is explicit at the call site. Every branch point is visible to the reader. + +```typescript +function isValid(result: Result): boolean { + return result.success && result.value >= 0 +} + +// call site — control flow is visible +const result = performProcess(param) +if (!isValid(result)) + throw new ProcessingError(result) +``` + +The feature-flag policy is at the call site, and the mechanism is a pure transformation: + +```typescript +function applyNewFeature(data: Data): Data { + return transform(data) // pure mechanism — always transforms +} + +// call site — policy is explicit +const output = featureEnabled ? applyNewFeature(baseData) : baseData +``` + +Logging follows the same pattern — the mechanism formats, the caller decides to log: + +```typescript +const summary = formatResult(result) // mechanism: returns string +logger.info(summary) // policy: caller decides to log +``` + + +### Functional Core, Imperative Shell + +Keep business logic in pure functions that take inputs and return outputs with no side effects. Push all side effects -- database calls, HTTP requests, logging, file I/O, and state mutations -- to an outer "imperative shell" that orchestrates the pure core. Pure functions are deterministic: given the same inputs they always produce the same outputs. This makes them trivially testable without mocks, easy to reason about, and safe to compose and parallelize. When side effects are mixed into calculation logic, tests become slow and brittle (requiring database stubs, log spies, HTTP interceptors), bugs hide behind non-deterministic execution, and refactoring becomes dangerous because any change might alter when and how I/O occurs. Separate what to compute from how to execute it. + +#### Incorrect + +Business calculation is tangled with logging, database reads, and persistence. Testing the pricing logic requires mocking the logger, database, and notification service. + +```typescript +async function applySubscriptionRenewal( + customerId: string, + logger: Logger, + db: Database, + mailer: Mailer +): Promise { + const customer = await db.customers.findById(customerId); + const plan = await db.plans.findById(customer.planId); + + // Pure calculation mixed with side effects + let price = plan.basePrice; + if (customer.loyaltyYears >= 3) { + price = price * 0.85; + logger.info(`Applied 15% loyalty discount for ${customerId}`); + } + if (customer.referralCount >= 5) { + price = price - 10; + logger.info(`Applied $10 referral credit for ${customerId}`); + } + const tax = price * customer.taxRate; + const total = price + tax; + + await db.invoices.create({ customerId, total, tax }); + await mailer.send(customer.email, `Your renewal total is $${total}`); + logger.info(`Renewal processed: ${customerId}, total: ${total}`); +} +``` + +#### Correct + +The pure core calculates the renewal price with no side effects.

When you need both a result and a side effect, split the operation into two explicit steps. + +#### Incorrect Mutation + +`applyNewFeature(result)` mutates its input but the caller uses the mutated object as if it were a return value. The mutation is invisible at the call site. + +```typescript +const result = {} +if (featureEnabled) + applyNewFeature(result) // mutates result — looks like command but used as query +``` + +Reassignment does not fix it when the function both mutates AND returns. The caller cannot tell whether the original was changed. + +```typescript +let result = {} +if (featureEnabled) + result = applyNewFeature(result) // unclear: does it mutate AND return? +``` + +#### Correct Pure Function + +Pure expression that returns a new value without mutating input. The call site clearly shows this is a query. + +```typescript +const result = featureEnabled ? applyNewFeature(baseData) : {} +``` + +#### Incorrect Hidden Command + +`validateResult` looks like a query but secretly throws, making it a hidden command. The call site hides a control flow branch. + +```typescript +const result = performProcess(param) +validateResult(result) // -> throws Error(...) — looks like query but is a command +``` + +#### Correct Explicit Control Flow + +Explicit control flow at the call site. The caller decides what to do with an invalid result instead of a hidden throw. + +```typescript +const result = performProcess(param) +if (!isValid(result)) + throw new SomeError(result) +``` + + +### Function and File Size Limits + +- Decompose functions longer than 80 lines into smaller, focused functions of 50 lines or fewer.

You analyse implementation steps and produce structured factors (rubrics, checklists, and scoring criteria) for evaluating each step of a task plan. You do NOT evaluate artifacts directly. Your job is to identify the important factors, along with detailed descriptions, that a verification judge would use to objectively evaluate the quality of an implementation step's result based on the step's instructions, success criteria, and expected output.

These are binary pass/fail requirements. + +Hard rules capture explicit, objective constraints (e.g., length < 2 paragraphs, required elements) that are directly or indirectly specified in the step. + +| Source | Example | +|--------|---------| +| Explicit instructions | "Must use TypeScript" → CK: "Is the implementation written only in TypeScript?" | +| Format requirements | "Return JSON" → CK: "Does the output conform to valid JSON?" | +| Quantitative constraints | "Under 100 lines" → CK: "Is the implementation exactly less than 100 lines?" | +| Behavioral requirements | "Handle errors gracefully" → CK: "Does every external call have error handling?" | +| Indirect requirements | "Write code" → CK: "Does the implementation have tests that cover changed code?" | + +#### 3.2 TICK Decomposition + +Decompose each step's success criteria into targeted YES/NO evaluation questions. The decomposed task of answering a single targeted question is much simpler and more reliable than producing a holistic score. + +**TICK decomposition process:** + +1. Parse the step's success criteria to identify every explicit requirement +2. Identify implicit requirements important for the step's problem domain +3. For each requirement, formulate a YES/NO question where YES = requirement met +4. Ensure questions are phrased so YES always corresponds to correctly meeting the requirement +5. Cover both explicit criteria stated in the step AND implicit quality criteria relevant to the artifact type + +Each checklist question must satisfy: + +| Property | Requirement | Bad Example | Good Example | +|----------|-------------|-------------|--------------| +| **Boolean** | Answerable YES or NO | "How well does it handle errors?" | "Does every API call have a try-catch block?" | +| **Atomic** | Tests exactly one thing | "Does it have tests and documentation?" | "Do unit tests exist for the main function?" | +| **Specific** | Unambiguous verification | "Does it follow clean code principles?" | "Does every function have a single return type?" | +| **Grounded** | Tied to observable artifacts | "Is the code maintainable?" | "Is every public function documented with JSDoc?" | + +#### 3.3 Checklist Assembly (Including Default Items) + +Combine hard rules from Step 3.1 and TICK items from Step 3.2 into the assembled checklist. Use these generation approaches as appropriate: + +1. **Direct** — generate checklist items directly from the step's success criteria alone (default approach) +2. **Contrastive** — if candidate results are available, identify criteria that discriminate between good and bad results +3. **Deductive** — instantiate checklist items from predefined category templates if available in the prompt or in project conventions (e.g., CLAUDE.md, AGENT.md, rules, skills, project constitution, CONTRIBUTING.md, README.md, etc.) +4. **Inductive** — extract patterns from a corpus of similar evaluations +5. **Interactive** — incorporate human feedback to refine checklist items + +Usually use **Direct** generation as the primary method, supplemented by **Deductive** based on available categories. + +Assign importance using this categorization: + +| Importance | Meaning | +|------------|---------| +| **essential** | Critical facts or safety checks. Must be met for a passing score; failure here = result is invalid and score is 1 | +| **important** | Key reasoning, completeness, or clarity. Strongly expected; missing it = automatic low score 1-2 | +| **optional** | Helpful style or extra depth; nice to have but not deal-breaking; improves quality but not required | +| **pitfall** | Common mistakes or omissions specific to this task; presence = quality reduction | + +**Essential items that are NO trigger an automatic score review.** If any essential checklist item fails, the overall score cannot exceed 2.0 regardless of rubric scores. + +**Pitfall items that are YES indicate a quality problem.** Pitfall items are anti-patterns; a YES answer means the artifact exhibits the anti-pattern and should reduce the score. + +##### Default Checklist Items (MANDATORY by default) + +In addition to step-specific hard rules and TICK items, every step that produces or modifies code MUST include the following default checklist items, populated from Stage 1's Quality Gates and Project Guidelines discovery: + +```yaml +checklist: + # Default: Quality gate items (one per discovered gate from Stage 1) + - question: "Does the build command pass with zero errors after this step?" + rationale: "Build failures block downstream work; the discovered build command must succeed." + category: "hard_rule" + importance: "essential" + # Include only if a build command was discovered in Stage 1. + + - question: "Does the lint command pass with zero new errors or warnings after this step?" + rationale: "Lint violations indicate convention drift; the discovered lint command must succeed." + category: "hard_rule" + importance: "essential" + # Include only if a lint command was discovered in Stage 1. + + - question: "Does the discovered test command run to completion with zero failing tests after this step?

Read **Decision Gates** in order (Gate 0 -> Gate 7). Each gate is independent — you may finish with any subset of test types ON. +2.

Equivalence Partitioning (EP) + +Divide input domain into partitions where the system is expected to behave the same way; ONE test per partition is sufficient. + +**Worked example** — `discount(orderTotal: number) -> number`: + +| Partition | Range | Representative test input | Expected | +|-----------|-------|---------------------------|----------| +| Below threshold | `0 <= total < 100` | `50` | `0% discount` | +| Mid tier | `100 <= total < 500` | `250` | `5% discount` | +| Top tier | `total >= 500` | `1000` | `10% discount` | +| Invalid (negative) | `total < 0` | `-1` | `throw / error` | + +Four tests cover all partitions. EP alone misses boundaries — combine with BVA. + +##### 2. Boundary Value Analysis (BVA) + +Bugs cluster at boundaries. For every boundary value `B`, test **`B-1`, `B`, `B+1`** (or for floats, the smallest representable step). + +**Worked example** — same `discount` function, boundary at `100`: + +| Test input | Why | Expected | +|------------|-----|----------| +| `99` (= B-1) | Last value of "below threshold" partition | `0% discount` | +| `100` (= B) | First value of "mid tier" partition | `5% discount` | +| `101` (= B+1) | Confirms not off-by-two | `5% discount` | + +Repeat for boundary at `500`: test `499`, `500`, `501`. Total: 6 boundary tests + 4 EP tests = 10 cases. + +The `B-1 / B / B+1` triplet has the same shape across boundaries (vary input, vary expected output, identical assertion); this is a natural fit for a **table-driven test** (see sub-section 5 below). + +##### 3. Decision Tables + +When output depends on combinations of conditions. Each column is a rule. + +**Worked example** — `canCheckout(cartHasItems, paymentValid, addressOnFile)`: + +| Condition / Rule | R1 | R2 | R3 | R4 | +|------------------|----|----|----|----| +| cartHasItems | T | T | T | F | +| paymentValid | T | T | F | * | +| addressOnFile | T | F | * | * | +| **Result** | allow | block:address | block:payment | block:cart | + +Four tests, one per rule (`*` = don't care, dropped via merging). + +##### 4. State Transition + +When behavior depends on history. Identify states, events, and forbidden transitions. + +**Worked example** — Order state machine with states `{draft, submitted, paid, shipped, cancelled}`: + +| From | Event | To | Test | +|------|-------|----|----| +| draft | submit | submitted | happy path | +| submitted | pay | paid | happy path | +| paid | ship | shipped | happy path | +| draft | cancel | cancelled | early cancel | +| paid | cancel | reject | forbidden — refund flow required, NOT direct cancel | +| shipped | submit | reject | forbidden | + +Cover one test per legal transition + one per forbidden transition (negative path). + +##### 5. Table-Driven Tests + +When EP, BVA, or decision-table analysis yields **3+ cases with the same shape** (same setup, same assertion, only inputs and expected outputs differ — e.g., parsing valid/invalid date formats; computing tax across brackets; routing rules) collapse them into a single **table-driven test**. The cases become rows in a data table; the test body iterates the rows and runs one assertion per row. -For each step requiring verification, design a rubric with: +Do **NOT** force a table when setup, framework calls, or the assertion shape varies substantially across cases. Forced uniformity hides real differences behind a single name and produces obscure failure messages — keep those as separate, individually named tests. -- **3-6 criteria** relevant to the artifact type -- **Weights summing to 1.0** -- **Clear descriptions** of what each criterion measures +**Worked example** — six EP+BVA cases for `discount(orderTotal)` (boundary at `100`) collapsed into one table-driven unit test (TS / vitest syntax; the same pattern applies to Go `t.Run`, JUnit `@ParameterizedTest`, pytest `parametrize`): + +```ts +describe("discount", () => { + const cases: Array<{ name: string; input: number; expected: number }> = [ + { name: "EP: below threshold (typical)", input: 50, expected: 0 }, + { name: "BVA: B-1 at boundary 100", input: 99, expected: 0 }, + { name: "BVA: B at boundary 100", input: 100, expected: 0.05 }, + { name: "BVA: B+1 at boundary 100", input: 101, expected: 0.05 }, + { name: "EP: mid tier (typical)", input: 250, expected: 0.05 }, + { name: "EP: top tier (typical)", input: 1000, expected: 0.10 }, + ]; + + for (const c of cases) { + it(c.name, () => { + expect(discount(c.input)).toBe(c.expected); + }); + } +}); +``` + +The `name` column is mandatory: each row must produce an individually addressable test so failures point to the specific case, not "row 3 of 6". Rows that need a different assertion (e.g., the negative-input case throws) stay as separate tests outside the table. + +--- + +#### Dependency Decision + +For Gate 2 (Integration) and Gate 3 (Component/E2E), choose dependencies deliberately. The goal is **maximum realism that still runs deterministically in CI**. + +| Dependency style | Use when | Avoid when | Notes | +|------------------|----------|------------|-------| +| **Real infra via Testcontainers** | DB/Redis/Kafka/Browser, dev needs real driver behavior, hermetic CI required | Cold-start budget < 1s, no Docker available | Default for integration tests on Postgres / Redis / Kafka / Localstack | +| **In-memory fake** | Owned interface, semantics are simple (key-value, list), test speed critical | Fake diverges from real — silent bugs at integration boundary | Acceptable for repository ports in hexagonal architectures, IF the port has its own contract test against real infra | +| **Mock (test double)** | Single collaborator with pure interface; test focuses on protocol (was X called with Y) | You're mocking >2 collaborators or mocking data structures (anti-pattern: incomplete mocks) | Mocks are tools to isolate, not things to test | +| **Stubbed HTTP** | Calling external SaaS where Testcontainers / Localstack option doesn't exist | When Pact / CDC is needed (use contract tests instead) | nock (Node), responses (Python), WireMock (JVM) | +| **Real external service** | Smoke test in staging only | Unit / integration / CI — always non-deterministic | Reserve for smoke tests against staging | + +**Tradeoff summary**: Testcontainers > in-memory fake > mock, but cost goes the same direction. Pick the cheapest level that doesn't lie about the boundary's behavior. + +--- + +#### Strategic Skip Heuristics + +Explicit "don't bother" rules. Skipping these is not laziness — it is risk-adjusted ROI. + +| Skip | Rule | +|------|------| +| **No e2e for internal helpers** | If artifact has no UI surface and no user-facing path, skip e2e. Unit + integration is sufficient. | +| **No contract test for bound by deploy consumer API** | If only one client consumes the API and they deploy together, contract testing adds maintenance with no decoupling benefit. | +| **No mutation on glue code** | Mutation testing on controllers, DTOs, framework wiring produces noise. Reserve for HIGH-criticality pure-logic core. | +| **No property-based on small finite domains** | If input space is `enum {A, B, C}`, EP + BVA already covers it; property-based adds infra without finding more bugs. | +| **No integration test for pure functions** | Adding a Postgres container to test a `formatCurrency` helper is waste.

After writing your prompt, you can launch the plugin and expect a working result when you come back. The time it takes depends on task complexity — simple tasks may finish in 30 minutes, while complex ones can take a few days. - **Benchmark-level quality in real life** — Model benchmarks improve with each release, yet real-world results usually stay the same. That's because benchmarks reflect the best possible output a model can achieve, whereas in practice LLMs tend to drift toward sub-optimal solutions that can be wrong or non-functional. This plugin uses a variety of patterns to keep the model working at its peak performance. - **Customizable** — Balance result quality and process speed by adjusting command parameters. Learn more in the [Customization](./customization.md) section. - **Developer time-efficient** — The overall process is designed to minimize developer time and reduce the number of interactions, while still producing results better than what a model can generate from scratch. However, overall quality is highly proportional to the time you invest in iterating and refining the specification. - **Industry-standard** — The plugin's specification template is based on the arc42 standard, adjusted for LLM capabilities. Arc42 is a widely adopted, high-quality standard for software development documentation used by many companies and organizations. - **Works best in complex or large codebases** — While most other frameworks work best for new projects and greenfield development, this plugin is designed to perform better the more existing code and well-structured architecture you have. At each planning phase it includes a **codebase impact analysis** step that evaluates which files may be affected and which patterns to follow to achieve the desired result. -- **Simple** — This plugin avoids unnecessary complexity and mainly uses just 3 commands, offloading process complexity to the model via multi-agent orchestration. `/sdd:implement` is a single command that produces working code from a task specification.
