The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). +## [1.2.0] - 2026-11-06 + +This release is about small models doing agentic work. The question going in was whether +better memory and a better translator would get a 1B model there. They help, and both got +work in this release, but the two biggest problems turned out to be somewhere else: + +1. **Ollama was throwing away the start of long prompts.** Nothing set the context window, + so every request got the server's default, which is 4,096 tokens on most laptops. + Anything longer lost its beginning, which is where the instructions and the task sit. +2. **Below about 3B, the action format is the bottleneck, not the coding.** Asked to change + one line in a 164-line file, `llama3.2:1b` could write the new line perfectly well. What + it could not do was copy the old line exactly into a JSON field so the extension could + find it. + +Both are fixed. On the new edit benchmark, `llama3.2:1b` went from 0 of 12 to 12 of 12 on +the suite used during development, and from 0 of 12 to 9 of 12 on a second suite written +afterwards in a different language, with no damaged file in any run. That second suite's +first run did find four failures, which were fixed, so it is not fully unseen either; the +details are in [benchmarks/README.md](benchmarks/README.md). + +**If you run a 3B model, try forcing the constrained tier for editing.** `llama3.2:latest` +(3.2B) is just over the line, so by default it runs the full tool loop, which does not use +dictated edits. There it passed 0 of 8 and 2 of 8. Forced onto the constrained tier with +`hirayacoder.model.tierOverrides` (`{"llama3.2:latest": "B"}`) it passed 16 of 16. The +default line has not moved, because the tier decides more than editing and the other +benchmarks have not been re-run with it moved. + +### Fixed: Ollama was silently cutting the start of long prompts + +Until now no request set `num_ctx`. Measured on machine B (Ollama 0.40, GTX 1650 Super): + +| Request | Prompt sent | Prompt Ollama kept | What was lost | +|---|---|---|---| +| `llama3.2:1b`, no `num_ctx` | 12,648 tokens | 2,050 | the instructions at the top | +| `qwen3.5:0.8b`, no `num_ctx` | 3,959 tokens | 2,050 | the first 31 of 60 requirements | + +The reply shares the same window, so the second request also stopped at 2,046 tokens of +output with `done_reason: "length"`. That is the "cut off before the code block ended" that +0.9.0 put down to `num_predict`. + +`core/contextWindow` now picks one window per model and the client sends it on every +request for that model: the agent loop, the translator, the planner and inline completion. +One number per model matters because Ollama reloads the model whenever `num_ctx` changes, +and a reload costs 7 to 10 seconds even for a 1B model. The window is sized for the largest +prompt the model's tier can send plus a full file of output (8k for the constrained tier, +16k for the full one), and capped at 16k by default because the machines this is built for +have 4 GB of VRAM or none. If the window is smaller than the tier would like, the prompt +budget shrinks to fit, so the extension trims by priority instead of Ollama trimming from +the top. + +New setting: `hirayacoder.ollama.contextLength`. `0` (the default) picks automatically. Set +a number to go higher if you have memory to spare, or lower to save it. + +The full-tool loop (Tier A) keeps the whole conversation, which is fine until it no longer +fits. It now makes room itself before Ollama does: old tool results are cut to their first +line and old `write_file` calls lose the file body they carried (it is on disk, one +`read_file` away). The system prompt, the task, and the last few messages are never touched. + +### Added: `edit_file`, for changing part of a file + +Until now, changing one line meant sending the whole file back. `edit_file` takes the exact +lines to replace (`find`) and what goes in their place (`replace`). It has no route of its +own to the disk: it works out the new content and hands it to `writeFile`, so the +permission gate, the diff, the content guards and the audit log all apply exactly as before. +It is listed before `write_file` on purpose, because small models lean towards the first +tool that fits. + +When `find` does not match, the refusal shows the closest lines in the file so the next try +can copy them. If it matches more than once, it asks for more context. If only the +indentation differs, it matches anyway, re-indents the replacement to fit, and says so in +the result. It is never fuzzier than that. + +### Added: dictated edits for small models + +`edit_file` alone was not enough for a 1B model. Measured on `llama3.2:1b`: it passed 0 of +12 with whole-file writes, and still 0 of 12 with `edit_file`, because it filled `find` with +words from the request (`"8%"`) instead of text from the file (`const TAX_RATE = 0.08;`). +Once told the text was not there, it lost the JSON format altogether. + +So on the constrained tier, when a request names exactly one existing file, the extension +does the finding itself. `core/editRegion` picks the lines the request is about by matching +its words against the file's identifiers (`TAX_RATE` is "tax rate" once split). The model +gets those lines and the request in plain words, and writes the new lines in a code block. +The answer goes in as an ordinary `edit_file`, through the same gate, diff and audit. This +is the 0.9.0 dictation finding (plain words beat JSON for small models) applied to edits. + +The answer is checked before anything is written: + +- **Nothing dropped.** Asked to make `applyDiscount` also reject percents over 50, the 1B + model replaced `percent < 0` with `percent > 50` three times out of three. A rewrite that + loses an existing check is refused with the check named. If it happens again, the model is + only asked for the new lines to put at the top of the function, next to a check it never + sees and so cannot lose. +- **Nothing out of scope.** New lines at the top of a function can only use what exists + there. Asked to stop overselling, the model wrote `if quantity > self.stock:` in a class + that has no `stock`. That is refused, not written. +- **No placeholders, no action objects, no whole-file rewrites.** `# ... rest unchanged` + and a JSON action pasted as code are both refused. +- **Indentation kept.** A rewritten method is placed at the depth it replaces. Before this, a + method written at column 0 closed its class early. +- **Additions go where additions go.** A new function goes above the export list and its + name is added to the list in one edit. A new method goes inside the class the request + names. + +If the region finder is not confident, or the file holds something the secrets scanner +would redact, nothing is dictated and the request goes to the normal loop, as before. After +a dictated edit the loop still runs if the request asked for more than one thing, and starts +out knowing what was already done. A single-part request that the edit finished simply +ends: measured, the 1B model did not recognise finished work and spent eight turns trying to +make the same change again. + +### Changed: the translator, in both directions + +From the model's work to memory: for a file change, the memory note is now read off the +change itself (`TAX_RATE = 0.08` became `0.1`, added `itemCount(cart)`) with no model call. +That is cheaper (one less inference per write) and it cannot be wrong about what changed. + +From the request to the model: the goal reminder used to repeat the first 240 characters of +the request. On a long brief those were the preamble ("You are an autonomous coding agent...") +and the work was further down. `distillTask` now keeps the sentences that ask for work, in +the user's own words and original order. `asksForMore` tells a one-part request from one +with a second part, which is what lets a finished dictated edit end the turn. + +### Changed: memory says what each changed file provides + +The "files you changed this session" block used to say `edited src/cart.js (+3 / -1)`. That +says the file was touched but not what to call. It now also lists what each file offers, +with arguments (`addItem(cart, product, quantity = 1)`), read from disk when the prompt is +built so it is never stale. `core/codeShape` reads this for CommonJS, ES modules, Python and +Java. The read is confined to the workspace, size-capped, redacted and neutralised, the same +as a tool read. + +### Changed: the panel + +- The header is two rows. The first says who and what (panel, session, model and tier). The + second has the run settings, with the mode first and the rarely changed toggles (Steps, + permissions, Guide) last and quieter. +- The Thinking control is labelled. Low, Med and High meant nothing on their own. +- Each reply's footer shows how much of the model's window the turn used + (`1.7k of 8k context`), from Ollama's own count, with a warning if the window filled. +- Each reply has a closed **What it remembered** panel showing the exact memory the model + was given. When an answer is wrong, this tells you whether the model had the wrong picture + or reasoned badly from the right one. +- The tier badge's tooltip now explains the window size too. +- The image button is a drawn icon. The emoji showed as a box in some editor fonts. +- In a narrow sidebar the key hint and the run status no longer fight for one line, and the + Steps panel no longer draws a stray rule when nothing is above it. + +### Fixed + +- **The generic error paragraph was being copied into files.** Refusals that already say + exactly what to send instead (a truncated file, removed exports, a missed edit, and + others) no longer get the generic "this failure does not match anything known" paragraph + appended. The 1B model was answering a missed edit with that paragraph as its `replace` + text. Repeats still escalate as before. +- **A new export with no definition.** Asked to add `itemCount(cart)` and export it, the 1B + model added `itemCount,` to `module.exports` and wrote no function, three runs out of three. + In CommonJS that breaks every file that imports the module. `writeFile` now refuses a + change that exports a name defined nowhere. +- **Three content guards contradicted their own message.** A write that removes exports, + exports a name it never defines, or drops an implementation is refused with a message + asking for the file again with the code intact. The loop then added "do not try that + again", which told the model the opposite. The hint now agrees with the refusal, as it + already did for the four older content guards. + +### Security + +Reviewed in [security/sast-report-2026-10-09-1.2.0.md](security/sast-report-2026-10-09-1.2.0.md). +Three fixes came out of it: a dictated edit no longer sends a file holding a secret to the +model unredacted, and two patterns that grew with the square of their input (one of them +took 44 seconds on a 200,000-character line) are now linear. The production dependency tree +is still empty. + +The development tree is back to zero advisories in `npm audit`, from 13 at the last check. +Nothing here ships, because the packaged extension contains no `node_modules`. Most came +out with `npm audit fix`. The rest needed `glob` 14 and `minimatch` 11 pinned under Mocha +and `vsce` with `overrides`, because no released version of either tool asks for them yet. + +### Developer tooling + +`tools/bench-edit.js` is a new benchmark: can a model change part of an existing file +without breaking the rest? Each task starts from a fresh fixture, runs through the real +`AgentSession`, and is graded by loading the file and running checks against it, never by +what the model said. Two suites: `cart` (CommonJS, used during development) and `inventory` +(Python with a class, held out). Results and method are in +[benchmarks/README.md](benchmarks/README.md). + ## [1.1.0] — 2026-08-21 HirayaCoder can look at pictures.

Findings Detail + +| ID | Tool | File:Line | Description | Severity | Status | Resolution / Justification | +|---|---|---|---|---|---|---| +| SAST-021 | Manual review, this pass | `app/agent/agentSession.js` (`_dictateEdit`), `app/agent/tools/editFile.js` (`EDIT_NOT_FOUND`) | **File contents reached the model unredacted on two new paths.** `read_file` passes everything through `redact` before the model sees it. The dictated edit reads the named file itself and sends the region, a related function and the file's signatures. And a missed `edit_file` answers with the closest lines of the file. Neither redacted. A key on or near the lines being edited went to the model as-is. | Low | **Resolved** | The two paths need different fixes. **`edit_file`'s refusal** is now redacted, the same as a `read_file` result: the model sees `[REDACTED:…]` and cannot copy that into `find`, which is correct. **The dictated edit** cannot simply redact, because the model's answer is written back over the lines it was shown, so a redacted region would put the marker in the file in place of the real key. So a file that holds anything the scanner redacts is not dictated at all: it goes to the ordinary loop, which reads it through `read_file`. Checked that neither benchmark fixture trips the scanner, so this does not quietly disable dictated edits. Both covered by tests that fail with the fix removed. Same class as SAST-020, and found the same way: by asking of each new path from a file to a prompt whether it goes through `redact`. The model is local, so nothing left the machine either way. | +| SAST-022 | ReDoS harness, this pass | `app/agent/dictation.js` (`outOfScope`, the declared-name pattern) | **Quadratic on one line of a workspace file.** `^(?:export[ \t]+)?(?:keyword)?[ \t]*(name)` gives two ways to spend one run of spaces after `export`. It runs on every line of a file up to 256 KB. Measured: `export` and 16,000 tabs, 284 ms; 64,000, 4.4 s; **200,000, 44 s**, blocking the extension host. Reachable from any file in the workspace that a request names, including one from a cloned repository. | Low | **Resolved** | The keyword now requires a space after it, so each run of spaces has one owner: 0.48 ms at 200,000. The same pattern was **also wrong on ordinary code**: with no space required, `constant = 1` read as the keyword `const` declaring `ant`, `letter` as `ter`, `classes` as `es`. A new line that used `constant` was then refused as out of scope. Both behaviours covered by tests. | +| SAST-023 | ReDoS harness, this pass | `app/core/editRegion.js` (`withExports`), `app/agent/dictation.js` (`extractEdit`, two sites; `extractCode`, one site) | **`/\s+$/` trims.** V8 retries the pattern from every position in a run of whitespace that something else follows, so it grows with the square of the run. On a 200,000-character line, **33.7 s**. `withExports` runs it on a line of the user's file. The `dictation` sites run on model replies, which `num_predict` bounds (about 24,000 characters at worst, roughly half a second). | Low | **Resolved** | Replaced with `trimEnd()`, which strips exactly the characters `\s` matches (checked on every Unicode space and line terminator) and is linear: under 0.01 ms at 200,000. The `extractCode` site predates 1.2.0 and is bounded by `MAX_CODE_CHARS`; it was changed anyway because the fix is one word and identical in effect. | +| SAST-024 | ReDoS harness, this pass | `app/core/contextTranslator.js` (`asksForMore`) | Splitting a request on joining words with `\s+(?:and\|then\|…)\s+`. Every position in a long run of spaces scanned to its end. Input is the user's own request, sliced to 20,000 characters, so the worst case was **0.34 s per turn**. | Info | **Resolved (hardening)** | The spaces are bounded to `\s{1,40}`: 5.7 ms at 20,000. Splits identically on ordinary requests (checked on a multi-clause sample). Covered by a timing test. | +| SAST-025 | ESLint `security/detect-unsafe-regex` | 24 new sites: `codeShape.js` (15), `dictation.js` (5), `editRegion.js` (2), `contextTranslator.js` (1), `agentSession.js` (1) | Patterns with adjacent optional groups, in the new parsing code. | Info | **Accepted, measured** | **Measured, not argued**, per the standing rule from 0.7.0. A harness parsed every regex literal in the 22 new or changed files (240 in all) and ran each against pumped input: 60 pump strings, every word in the pattern as a prefix, four suffixes, at 4,000 and 16,000 characters. Every pattern ESLint flagged in the new modules stayed under 2 ms at 4,000 characters, i.e. linear. Most had been fixed during development (the comments in `codeShape.js` and `dictation.js` record the measurements: one took 17 s on 80,000 blank lines before `^\s*` became `^[ \t]*`). The super-linear patterns the harness did find were mostly **not** flagged by ESLint; the reachable ones are SAST-022 to SAST-024, and the rest run on input capped well below where they matter (a 160-character filename candidate, a 180-character phrase, a 2,000-character export list, a 4,000-character related file, a path under `MAX_PATH_LENGTH` with no newlines). | +| SAST-026 | ESLint `security/detect-object-injection` | 18 new sites: `editRegion.js` (14), `editFile.js` (3), `agentSession.js` (1) | Bracket access with a computed key. | Info | **Accepted, reviewed** | Every one is a numeric index into a local array of lines (`lines[index]`, `lines[best]`, `lineWords[best]`), counted by a loop or returned by `findIndex`. No string key from a file, the model or the settings reaches any of them. | +| SAST-027 | `npm audit` | `package-lock.json` (dev tree) | **New advisories since 1.1.0, dev dependencies only.** `brace-expansion` (GHSA-q2hr-2g5m-vwhr, GHSA-qhr7-859c-m2p7, GHSA-6j4f-fj2g-mc7p: quadratic expansion and unbounded recursion), pulled in by ESLint and Mocha. `braces` (GHSA-vfj7-8cjw-p6xm, stack exhaustion), pulled in by `@vscode/vsce` through `secretlint`, `globby`, `fast-glob` and `micromatch`. | Low | **Resolved** | Not shipped: production dependencies are empty and `vsce ls` lists nothing from `node_modules/`. By 2026-11-06 the count had grown to 13 (7 high, 5 moderate, 1 low), all in the dev tree. `braces` was no longer among them. `npm audit fix` cleared 9, including `brace-expansion`, `undici` and `markdown-it`, with no breaking change. The last 4 were `glob` and `minimatch` under Mocha and `@vscode/vsce`. Current Mocha 12 still asks for a vulnerable `glob`, so upgrading would not have fixed it. They are pinned with `overrides` scoped to those two tools (`glob` ^14.0.3, `minimatch` ^11.0.5), the approach 0.7.0 used for Mocha, and ESLint keeps its own `minimatch` 3. `npm audit` reports zero, and lint, the unit suite and `npm run package` pass with the pins. Remove the pins once both tools depend on fixed versions themselves. | +| SAST-017 | Semgrep `javascript.lang.security.detect-child-process` | `tools/bench-build.js:290`, `tools/bench-realworld.js:99`, `tools/lib/javaProbe.js:44`, `tools/lib/pythonProbe.js:351`, and new: **`tools/bench-edit.js:103`** | `spawnSync` in the benchmark harnesses. | Low (rule) | **Accepted** | Developer tooling, not shipped. The new site runs `node -e` or `python -c` with a check from the fixture against the file the model edited, so it **executes model-written code on the developer's machine**. That is what grading by running means, and it is the same as `bench-build`. The bounds are a fresh temporary directory per task, a 10-second timeout, an argument array with no `shell`, and a file whose only author is a local model working on a 164-line fixture. Run it on a machine where that is acceptable. | +| SAST-004 | Semgrep `javascript.lang.security.detect-child-process` | `app/security/scriptRunner.js:451` | Carried forward. `spawn()` reached from the `command` and `options` arguments. Impact HIGH, **confidence LOW**. | High (rule) | **Accepted, unchanged** | The only `child_process` call in shipped code, in the module that exists to make it safe: argument array with `shell: false`, `argv[0]` checked against the allow-list, shell metacharacters rejected, Windows `.cmd` shims pre-screened, and a `permissionGate` approval required.

(`core/missingDeps.js` contains the string only as a + Node builtin name in a list.) No 1.2.0 module opens a process. +- [x] **Path traversal: the new file reads.** Two new reads put workspace content in a prompt. + `agentSession._singleNamedFile` reads a file the user's request names; `fileHistory._shapeOf` + reads a file the session changed. Both go through `pathGuard.resolvePath` and then + `assertRealPath`, so a symlink cannot reach outside the workspace, then `stat` with a + 256 KB cap **before** the read, and a NUL-byte check after. A name that fails any of + these is skipped, not reported, because plenty of words in a request look like filenames. +- [x] **The new write route.** None. `edit_file` reads through `gate.requestRead` and writes by + calling `writeFile` with the full new content, so the gate, the diff the user approves, + every content guard and the audit entry are the same as for `write_file`. Verified by a + test in which the user declines and the file stays unchanged. The dictated edit applies + its result through `_execute` as an ordinary `edit_file` action. +- [x] **Secrets on the new paths.** SAST-021. Also checked: the signature lines `fileHistory` + adds to memory are redacted before `codeShape` reads them and neutralised before they + are stored, and the memory note the panel shows is the same text the prompt got. +- [x] **Model output crossing into the file.** The dictated edit's answer is checked before it + is written: no dropped comparison, no name that does not exist at the insertion point, + no placeholder comment, no JSON action object, no reply far longer than its region. Then + `writeFile`'s guards run as for any write. These are correctness guards, but they are + also what stops a confused reply from being written over working code. +- [x] **The webview.** `messageBubble.appendMemoryNote` and the new context reading build with + `createElement` and `textContent`; there is no `innerHTML` in the file. Memory lines are + neutralised before they are stored and stay text here. +- [x] **The new setting.** `hirayacoder.ollama.contextLength` is a number the user sets for + their own machine. It is floored at 2,048 and capped at the model's own trained maximum. + A very large value costs the user memory on their own GPU; it opens nothing. +- [x] **The network path** *(unchanged)*. `num_ctx` is a field in the body of a request the + loopback-only client already sends. No new endpoint, host or protocol. +- [x] **Denial of service.** SAST-022 to SAST-024, measured. The new reads are size-capped + before reading. The dictated edit is at most three model calls with `num_predict` 1,500 + and a three-minute timeout each. +- [x] **Permissions and path confinement** *(unchanged)*. No change under `app/security/`. +- [x] **Shipped artefact contents.** `npx vsce ls` reviewed in full: 101 files, the 4 new being + the 4 new modules. `tools/lib/cartFixture.js`, `tools/lib/inventoryFixture.js` and the new + benchmark results are not packaged. + +## 5.
