RossoCortex validates the identity of the + caller. It confirms that a user with the correct role sent the request. +2. **Outbound request.** Traffic that the agent starts. RossoCortex confirms that the agent can reach + the target for this user. It also examines the content for sensitive data. +3. **Outbound response.** The reply to a request from the agent. RossoCortex examines the reply for an + attempt to control the agent. +4. **Inbound response.** The reply from the agent to its caller. RossoCortex examines the reply for + data that the user must not receive. + +Most platforms control point 1 only. Points 2 and 3 are necessary for agents. An agent that reads a +document with a hidden instruction can send a correctly authenticated request that no user asked for. + +### The plugin chain + +Each control point runs an ordered chain of plugins. A plugin can read the traffic, add data to a +shared record, change the content, or stop the request. + +The default chain controls identity and delegation. + +| Plugin | Control point | Function | +| --- | --- | --- | +| `jwt-validation` | Inbound request | Validates the signature, the issuer and the audience of the token. Returns 401 if the token is not valid. | +| `token-exchange` | Outbound request | Exchanges the token, so the agent presents a token that is valid only for the target. | + +Every other plugin is optional. Parser plugins read the traffic and record its structure, so that a +later plugin can examine it. The parsers are `a2a-parser`, `mcp-parser` and `inference-parser`. + +The optional control plugins use those records. See the +[Experiments](../index.md#experimental-features) group for each one, and the +[plugin catalogue](https://github.com/rossoctl/cortex/blob/main/authbridge/docs/plugin-catalog.md) +for the configuration of each one. + +### Authentication and authorization are separate decisions + +The chain treats the two decisions differently. + +**Authentication answers one question: is this identity real?** A token that is absent or invalid is +rejected at once. There is nothing to evaluate, and an early rejection protects the platform. + +**Authorization answers a second question: can this identity do this action?** Here a plugin +records its result. One decision point then evaluates each record together. + +The reason is operational. One request from a user can produce many requests inside a group of agents. +Each plugin at each control point can stop traffic. A cluster then has thousands of independent +decisions, and no single place to examine after a task fails. One record and one decision point keep +both the decision and the audit data in one place. + +RossoCortex is moving to [CPEX](https://github.com/contextforge-org/cpex) for that decision layer. +CPEX combines the results of policy engines such as Cedar and OPA.

Cortex prices the tokens in four categories, because each category +has a different rate. + +| Category | What it is | Why it is separate | +| --- | --- | --- | +| **Input** | The prompt tokens that the model read for the first time | You pay the full rate for these. | +| **Cache write** | The prompt tokens that the model wrote to its cache | More than the input rate. This is the one-time cost to store the prompt. | +| **Cache read** | The prompt tokens that the model read from its cache | Much less than the input rate. This is caching that operates. | +| **Output** | The tokens that the model generated | | + +Cortex also captures a **reasoning** count. These are the output tokens that the model used to reason, +on a model that reports them. They are a part of the output count, not a fifth priced category. + +### Why cache read and cache write are two numbers + +A model can cache a part of your prompt. The next call that sends the same part reads it from the +cache. This is useful for a coding agent, because the agent sends the same system prompt and the same +files on each turn. + +The two cache numbers have different prices, so Cortex keeps them apart: + +- **A cache write costs more than an input token.** You pay a premium once, to store the prompt. +- **A cache read costs a fraction of an input token.** You save on each later turn that reuses the + prompt. + +The split tells you whether caching earns its cost: + +- A large **cache-read** count means the cache operates. You pay the low rate for most of the prompt. +- A **cache-write** count that repeats, with little cache-read, means the cache does not hold. You pay + the premium again and again and get no saving. This happens when the prompt changes on each turn. + +## Read the cost + +Cortex applies a price to each token category and adds the results. The figure is the cost of the +session. + +- **The cost is an estimate, unless the provider returns an exact figure.** Cortex computes the cost + from published rates for each model. When the provider returns an exact cost (for example, the + `x-litellm-response-cost` header from LiteLLM), Cortex uses that figure instead. +- **The rates come from a table for each model.** A model that Cortex does not recognize has no rate. + Cortex then shows no cost for that call, rather than a misleading zero, even though the token counts + are still correct. A blank cost with correct tokens means the model is unpriced, not free. + + + +## Read the sessions table + + + +The Sessions view is the table that you land on.

It is empty for a session that nothing named. | +| `UPDATED` | The time since the last event. | +| `EVENTS` | The count of the calls in the session. | +| `TOKENS` | The token total for the session. | +| `COST` | The cost of the session. | +| `SAVED~` | The cost that a reduction plugin avoided. | +| `CONTEXT(1M)` | How full the context of the conversation was on its last turn. | + +An em dash (`—`) means that Cortex has no figure. It does not mean zero. A session with tokens and no +cost holds a model that the rate table does not name. + +The two money columns need a terminal of 97 columns or more. On a narrower terminal Cortex removes +both columns. It does not show a rounded figure in their place. + +### Read the context gauge + +`CONTEXT(1M)` is a gauge, not a figure. It shows how full the context of your conversation was on its +last turn, against a window of one million tokens. The brackets are the scale, and Cortex draws them +on each row. An almost empty session therefore reads as empty, and not as a blank cell. + +Claude Code sends three kinds of traffic under one session identifier: your conversation, the +subagents that it starts, and its own short internal calls. The gauge follows your conversation only. +It reads the last turn of that conversation, and it does not average a set of recent turns. + +## Read the spend band + +The four figures above the table are the spend band. Each cell covers one period, and the label names +the period. + +| Cell | Period | +| --- | --- | +| `LAST 1H` | A rolling hour. | +| `TODAY` | From local midnight to now. | +| `7 DAYS` | A rolling seven days. | +| `MONTH` | From the first day of the local month to now. | + +`TODAY` and `MONTH` are boundaries, and not lengths. Each one is narrow at the start of its period, +and it widens through the period. `7 DAYS` is a rolling window, so it is the one cell that no calendar +edge aligns to. Compare `7 DAYS` against `MONTH` with that difference in mind. + +A cell that shows `—` is a period that your deployment cannot answer. Three of the four cells read +from a cost ledger. A local install holds that ledger, and Kubernetes does not hold it by default. +Cortex shows `—` in place of a figure that covers a shorter period than the label states. + +A cell also carries its own age when its data stops arriving. `TODAY 7m` is a figure from seven +minutes ago. Each cell polls on its own schedule, so the age belongs to the cell and not to the band. + +:::note The band and the table cover different periods +The `COST` column of the sessions table can add up to less than `TODAY`. The session store is in +memory, so the table reaches back only to the start of the current proxy process. `TODAY` reads from +the cost ledger on disk, and it survives a restart of the service. A table that adds up to less than +the band is therefore correct after a restart. +::: + +### Read the spend breakdown + +Press `$` to expand the band. The breakdown holds two columns: + +```text + WHERE IT WENT BY MODEL +output ██████ $2.70 claude-opus-5 $4.55 35 req 5.6M tokens +cache-read ███▌ $1.62 +input ▍ $0.22 +cache-write — + [a] [model] · endpoint · agent [w] 1h esc closes +``` + +The left column is the four rate tiers. They are the same four token categories that +[Read the tokens](#read-the-tokens) describes, priced. The right column is who spent the money. Press +`a` to change it between the model, the endpoint and the agent. Press `w` to change the period. + +Cortex models the tier figures from the rate table. It does not measure them. A gateway reports one +figure for a call, and it never divides that figure by tier. Cortex apportions the tiers, so the column +adds up to the total of the period. A tier that the rate table does not name reads `—`, and not +`$0.00`, because `$0.00` claims that the tier is free. + +## What a marker on a figure means + +A figure carries a marker when Cortex cannot state it exactly. A figure with no marker is exact. + +| Marker | Meaning | +| --- | --- | +| `~` | The figure is an estimate, so it is a lower bound and not an exact total. | +| `+` | The figure is a floor. Cortex could not price some traffic, or the period reaches past what the ledger holds. | +| `!` | The figure is short by an amount that Cortex cannot state. | + +The `~` on `SAVED~` sits in the heading, and not on each value. Cortex estimates each saving, so a +marker on each row distinguishes nothing. + +## How precise a money figure is + +Cortex shows money in one of two forms, and which form depends on the surface. + +- **Cents.** The four cells of the spend band, the `COST` and `SAVED~` columns of the sessions table, + the `COST` of the usage charts, and both columns of the spend breakdown. You read these figures down + a column, and you compare them against each other. Two more digits add noise. +- **Four decimals.** The `COST` column of the events table. One request costs $0.000038, so cents + render a whole column as the same value. + +Cortex never prints a figure above zero as `$0.00`. A cents figure below one cent reads `<$0.01`, and a +four-decimal figure reads `<$0.0001`. A figure of zero is a claim about the traffic, and never the +result of rounding. + +## Read the cost of a longer period + +`abctl cost` prints the spend for one period, without the terminal interface. + +```bash +abctl cost # today, from local midnight +abctl cost --window month # this month, from the first day +abctl cost --window 7d # the last seven days +abctl cost --window 1h # a rolling hour +abctl cost --json # the totals as JSON, for a script +``` + +The command prints the period that the proxy answered, and not the period that you asked for. A +deployment with no cost ledger answers with the longest period that it holds. A figure of six hours +under the label of a month understates the month, so Cortex names the period it served. + +## Read the usage charts + +Press `u` to open the usage charts. The charts show one metric over one time window. Four keys change +what you see. + +| Key | Action | +| --- | --- | +| `m` | Change the metric: tokens, requests, errors, latency or cost. | +| `w` | Change the window: 10 minutes, 1 hour or 6 hours. | +| `b` | Change the breakdown: none, status, method or plugin. | +| `s` | Change between this session and all of the sessions. | + +The latency metric has no breakdown. Cortex records latency for a call, and not for a label. + +`abctl` writes your choice of metric, window and breakdown to `~/.cortex/abctl-config.yaml`. The charts +open with the same choice the next time. `abctl` also writes the column selection and the filter of the +events table to that file. + +## Read the latency + +Cortex records two times for each model call. + +- **Time to first token.** The time from the request to the first part of the reply. For a reply that + streams, this is the time until you see the first word. It is the number that decides how fast the + agent feels. +- **Total response time.** The time from the request to the last part of the reply. It depends on the + length of the reply. + +For a set of calls, Cortex reports percentiles. + +- **p50** is the middle value. Half of the calls are faster. It is the typical experience. +- **p95** and **p99** are the slow calls. Ninety-five or ninety-nine percent of the calls are faster. + These are the calls that a user notices. A p50 that is good with a p99 that is bad means that most + calls are fast, but the slow calls are very slow. + +## Read the pruning savings + +If you enable tool pruning, Cortex removes the tool definitions that the agent does not use, before +the request goes to the model. The savings figure is the tokens and the cost that the pruning +removed. See [Cost control](../concepts/experiments/cost-control.md). + +- **A figure above zero** is the saving for that session. You paid less because Cortex sent a smaller + request. +- **A figure of zero** means that Cortex removed nothing. The usual cause is an agent with no tools. + An agent that sends no tool definitions has nothing to prune, so zero is the correct figure and not + a failure. + +This figure is the answer to one question: what does pruning do for me? You enable pruning, you read +the figure, and you decide if the saving is worth the feature. + +## A worked example + +:::note +These are representative figures for the data that Cortex captures. They show the shape of a real +session. Replace them with a session that you capture before you rely on the exact values. +::: + + + +One session of a coding agent, with tool pruning enabled: + +| Field | Value | +| --- | --- | +| Model | `claude-sonnet-4` | +| Events | 34 | +| Input tokens | 12,400 | +| Cache read | 486,000 | +| Cache write | 61,200 | +| Output tokens | 8,900 | +| Reasoning tokens | 3,100 | +| Cost | 2.14 USD | +| Time to first token (p50) | 0.7 s | +| Time to first token (p95) | 2.9 s | +| Total response time (p95) | 24 s | +| Tokens pruned | 41,000 | +| Cost saved by pruning | 0.12 USD | + +How to read it: + +- **Caching operates.** The cache-read count (486,000) is much larger than the input count (12,400). + The agent sends the same context on each turn, and the model reads almost all of it from the cache. + Without the cache, the input cost is many times higher. +- **The cache-write count is a one-time cost.** The 61,200 cache-write tokens are the first turn that + stored the context. Later turns read it, and do not write it again. +- **The slow tail is visible.** The typical first token arrives in 0.7 s, but the slowest calls take + 2.9 s. If the agent felt slow, the p95 is the reason, not the p50. +- **Pruning earns a small amount here.** It saved 0.12 USD, because it removed 41,000 tokens of unused + tool definitions across the session. On an agent with many tools, this figure is larger. + +## Why leave Cortex running + +One session is useful. A week of sessions is more useful. The value is in the change over time: + +- A prompt that grows more expensive each day. +- A cache-read count that falls, because a change to the agent broke the cache. +- A session that costs ten times the others. + +You see these only if Cortex runs while you work. It runs as a background service and adds no step to +your day. See [Manage the service](laptop.md#manage-the-service). + +## Give feedback + +Did the numbers tell you what you needed, or not?

The agent calls the MCP server. It does not know a broker exists. +2. The sidecar matches the target host against a `broker` route and asks the token broker for a + token. +3. No token is cached, so the broker discovers the resource server's OAuth provider from + `GET /.well-known/oauth-protected-resource` ([RFC 9728][rfc9728]). +4. The broker publishes an `oauth_url_ready` event. The UI opens the provider's consent page. +5. The user consents. The provider redirects to the broker's callback, which exchanges the code + for an access token and caches it per `(session, resource)`. +6. The sidecar attaches the token and completes the original call. The agent gets its response. + +The agent is involved only at steps 1 and 6. Repeat calls are served from the cache with no +further consent. + +[rfc9728]: https://datatracker.ietf.org/doc/html/rfc9728 + +## Prerequisites + +### 1. A platform install + +```bash +scripts/kind/setup-rossoctl.sh --with-ui --with-spire --with-agent-sandbox --with-builds --preload-images +``` + +Budget about 12–16 GB of memory and 4 vCPUs. `--with-all` is not needed for this demo. + +### 2. A GitHub OAuth app + +Create one at [github.com/settings/developers](https://github.com/settings/developers) → +**OAuth Apps** → **New OAuth App**: + +| Field | Value for a Kind cluster | +| --- | --- | +| Application name | anything, for example `rossoctl-hitl-dev` | +| Homepage URL | `http://rossoctl-ui.localtest.me:8080` | +| Authorization callback URL | `http://token-broker.localtest.me:8080/oauth/callback` | + +The callback URL must equal `tokenBroker.oauth.callbackUrl` in the operator chart exactly, or +GitHub rejects the redirect. Generate a client secret — GitHub shows it once. + +Store it in the release namespace. The chart never templates credentials, so they stay out of +values and Helm release state: + +```bash +kubectl create secret generic github-oauth-credentials -n rossoctl-system \ + --from-literal=client-id= \ + --from-literal=client-secret= +``` + +### 3. The token broker + +It ships inside the operator image and is off by default: + +```bash +helm upgrade rossoctl charts/rossoctl -n rossoctl-system --reuse-values \ + --set operator-chart.tokenBroker.enabled=true +``` + +Expect `token-broker` to reach `1/1 Running` in `rossoctl-system`. A pod stuck in +`CreateContainerConfigError` means the secret above is missing. + +### 4. An OAuth-protected resource server + +This is the step most easily missed. The broker cannot mint a token without a resource server +to run discovery against, and the demo server is not part of this repository — it is a fork of +GitHub's MCP server that adds the OAuth endpoints and Kubernetes manifests. + +```bash +# In your checkout of the MCP server fork +docker build -f k8s/kind-demo/Dockerfile.mcp-server -t localhost/kagenti/mcp-server:demo . +kind load docker-image localhost/kagenti/mcp-server:demo --name rossoctl + +kubectl create namespace rossoctl-demo +kubectl create secret generic github-oauth-credentials -n rossoctl-demo \ + --from-literal=client-id= --from-literal=client-secret= + +# The manifest predates the rename and still says namespace: kagenti-demo. +sed 's/namespace: kagenti-demo/namespace: rossoctl-demo/' k8s/kind-demo/02-mcp-server.yaml \ + | kubectl apply -f - +``` + +Do **not** run that repository's `k8s/kind-demo/build-and-deploy.sh`. It also deploys its own +token broker and backend into pre-rename namespaces, which collides with the broker the +operator chart installs. + +Check discovery works: + +```bash +kubectl exec -n rossoctl-system deploy/app-demo-backend -- python3 -c " +import urllib.request +print(urllib.request.urlopen( + 'http://mcp-server-service.rossoctl-demo.svc.cluster.local:8184/.well-known/oauth-protected-resource', + timeout=8).status)" +``` + +## Switch the outbound chain to the token broker + +`token-exchange` and `token-broker` both claim the `Authorization` header, so they are mutually +exclusive on the outbound chain. Swapping them means editing `authBridge.pipeline`, upgrading +the release without letting Helm undo the change, and restarting every injected workload. Use +the script rather than doing it by hand: + +```bash +scripts/migrate-to-token-broker.sh # switch to token-broker +scripts/migrate-to-token-broker.sh --revert # switch back +``` + +It checks the prerequisites, reads the pipeline the release is actually running, and exits +without changes if the target plugin is already active. It never writes to the chart. + +Confirm the result: + +```bash +kubectl get cm authbridge-runtime-config -n team1 -o yaml | grep -A6 'name: token-broker' +``` + +### Why the chart value, and not `pluginPreset` + +`AgentRuntime.spec.pluginPreset` with `plugins: ["token-exchange:off", "token-broker:enforce"]` +looks like the natural way to do this, and admission accepts it — but the sidecar then +crash-loops: + +``` +initial pipeline build: outbound: configure "token-broker": token-broker config: broker_url is required +``` + +The operator seeds each plugin's config from a base pipeline that only covers `jwt-validation` +and `token-exchange`, so `token-broker` renders with no config at all. Editing the per-agent +`authbridge-config-` ConfigMap does not help either: the admission webhook regenerates it +on every pod creation. + +So `authBridge.pipeline` is the durable path today. + +### Route rules + +The plugin brokers only for hosts matching a `broker` route; everything else passes through +untouched. The script writes an inline rule for the MCP server. You can also mount rules from a +ConfigMap named `authproxy-routes` (key `routes.yaml`, mounted at `/etc/authproxy/routes.yaml`): + +```yaml +- host: "mcp-server-service.rossoctl-demo.svc.cluster.local" + action: "broker" +``` + +File routes are evaluated before inline rules, the first match wins, and the port is stripped +before matching. + +### Point an agent at the resource server + +The agent's `MCP_URL` lives on the Sandbox, not the AgentRuntime: + +```bash +kubectl get sandbox -n team1 -o json \ + | jq '.spec.podTemplate.spec.containers[0].env[] | select(.name=="MCP_URL")' +``` + +Set it to the in-cluster address: + +``` +http://mcp-server-service.rossoctl-demo.svc.cluster.local:8184/mcp +``` + +Use `http`, not `https`. Cortex passes TLS through untouched, so the plugin cannot insert a +token into an encrypted stream — pointing an agent at a hosted HTTPS MCP endpoint skips the +broker entirely. + +## Run the demo + +Deploy the example app and grant a user access: + +```bash +cd rossoctl/examples/app-demo +DOCKER_BUILD_FLAGS=--load make all # --load is required with podman +make grant-agent-access +``` + +Give a user the operator role. Note the flag is `--uusername`; current Keycloak rejects the +`--uname` shown in some older instructions: + +```bash +KC_ADMIN_USER=$(kubectl get secret keycloak-initial-admin -n keycloak -o jsonpath='{.data.username}' | base64 -d) +KC_ADMIN_PASS=$(kubectl get secret keycloak-initial-admin -n keycloak -o jsonpath='{.data.password}' | base64 -d) +kubectl exec -n keycloak keycloak-0 -- /opt/keycloak/bin/kcadm.sh add-roles \ + -r rossoctl --uusername alice --rolename rossoctl-operator \ + --no-config --server http://localhost:8080 --realm master \ + --user "$KC_ADMIN_USER" --password "$KC_ADMIN_PASS" +``` + +Log out and back in so the role lands in a fresh token, then open +`http://app-demo.localtest.me:8080` in a private window, sign in, pick a namespace, and send a +task to an agent. + +### Exercising the broker without the UI + +Useful for isolating the broker.

Without `--host`, MLflow listens on the loopback address, which a container +cannot reach.

Kubernetes does not hold it by default, so those three periods have +no figure. `LAST 1H` reads from memory, and it always has one. + +**A spend cell carries a time, such as `TODAY 7m`.** The figure is seven minutes old, because the +data for that cell stopped arriving. Each cell polls on its own schedule, so the age belongs to the +cell. + +**A figure carries `~`, `+` or `!`.** Each marker states what Cortex cannot state exactly: `~` is an +estimate, `+` is a floor, and `!` is short by an amount that Cortex cannot measure. See +[What a marker on a figure means](../get-started/reading-the-numbers.md#what-a-marker-on-a-figure-means). + +**One request costs `$0.000038`, and the session shows `<$0.01`.** The two surfaces use two +precisions.

See +[How precise a money figure is](../get-started/reading-the-numbers.md#how-precise-a-money-figure-is). + +**The context gauge is almost empty, and the agent is busy.** The gauge follows your conversation +only.

It exits with the code 4 when the first identity document expires in less than +`CERT_WARN_SECONDS`, which is 6 hours by default. The script needs `kubectl` access and `jq`. On Kind you +can also enable the `meshSelfHeal` feature flag, which adds a CronJob that does the restart. + +**Expect this condition on a development cluster.** After a long suspension, you must restart the +data plane or create a new cluster.

A number alone means `http:::TCP`: + +```bash +rossoctl tools import from-image --name weather-mcp --containerImage ghcr.io/x/y:latest \ + --ports grpc:9000:9001:TCP,8080 +``` + +A tool that Rossoctl builds from source reports `Building` until the build ends. A build often needs more +time than the default limit of 60 seconds. Give a longer limit. If the build fails, the command reports +`Build Failed` and exits at once. + +:::note +Against the local `cortex` context, the `tools wait` command reaches its time limit. That server does not +have the endpoint that the command reads, and the `tools get` command fails for the same reason. Use +`tools list` for a local tool.

For an +address, the command writes the content to a temporary file and deletes that file when it exits. + +The command gives each argument after `--` to your program without a change. It exits with the exit status +of your program. + +The command sets `HTTP_PROXY` for the proxy. It sets `HTTPS_PROXY` and the certificate variables also when +the TLS bridge runs. The certificate variables are `NODE_EXTRA_CA_CERTS`, `REQUESTS_CA_BUNDLE` and +`SSL_CERT_FILE`. The command does not change a variable that you already set. It stops each part when your +program exits, and also on a `SIGINT` signal or a `SIGTERM` signal. + +| Option | Function | +| --- | --- | +| `--config FILE\|URL` | Necessary.

It then starts the +OpenTelemetry collector with that file. The collector receives OTLP on port 4317 for gRPC and on port 4318 +for HTTP. The command needs `docker` or `podman` on your path. The container runs in the background. To +stop it, use `podman stop` or `docker stop` with the name that the command printed. + +The default `--traces_endpoint` value reaches your computer from inside the container. Inside the +container, the name `localhost` means the collector. + +The command records two values in `~/.config/rossoctl/otel-config.yaml`. The first value is the path of +the configuration file. The second value is the address that a client uses to reach the collector, which +is `127.0.0.1:4318`. That address is the address to send to, and not the `0.0.0.0` address that the +collector listens on inside the container. + +The `send-mock-trace` command sends one span. Use it to test the path from your computer to your trace +store, without an agent. The `--serviceName` option sets the `service.name` attribute.

It is not the +context window of a model. Context Service provides it. See +[Agent context](../concepts/experiments/agent-context.md). + +## AgentRuntime + +The Kubernetes resource that adds a workload to the platform.

You can evaluate the feature. The behaviour and the interface will change. Do not depend +on it. See [Concepts](../concepts/index.md#maturity-levels). + +## Ambient mesh + +The mode of Istio that gives mTLS between workloads without a sidecar. The `ztunnel` DaemonSet provides +it. The `--with-istio` option installs it. It is different from the Istio gateway controller, which +Rossoctl always installs. + +## AuthBridge + +The identity and access control part of RossoCortex. It validates each token that arrives, and exchanges +each token that leaves. See [AuthBridge](../security/authbridge.md). + +## Beta + +A maturity level. The feature operates and this site documents it. The configuration can change in a later +release. See [Concepts](../concepts/index.md#maturity-levels). + +## Context compaction + +A method that makes tool output smaller before a model reads it. A task with more output than the context +window then completes. The plugin is `context-guru`.

RossoCortex uses it to add its Go logic to the Envoy proxy. + +## Feature gate + +A setting in the `rossoctl-feature-gates` ConfigMap. It applies to the whole cluster. A namespace cannot +replace it, and a workload cannot replace it. See +[Custom resources](custom-resources.md#configuration-layers). + +## IBAC + +See [Intent-based access](#intent-based-access). + +## Identity binding + +A check that the SPIFFE identity that signed an agent card is the identity of the workload that the card +describes. The default mode writes the result to the status. The strict mode starts a network isolation +after a failure. See +[Control plane](../concepts/core/control-plane.md#identity-binding). + +## Intent + +The request of a user. The `a2a-parser` plugin reads it from a message and records it. The intent-based +access plugin compares each action with it. + +## Intent-based access + +A method that denies an outbound action that does not match the most recent request of the user. A model +makes the comparison. The plugin is `ibac`. See +[Intent-based access](../concepts/experiments/intent-based-access.md). + +## JWKS + +A JSON Web Key Set. It contains the public keys that RossoCortex uses to validate the signature of a +token. Keycloak provides it. + +## Keycloak + +The identity provider. It authenticates users, holds the roles, issues access tokens and exchanges tokens. +Each agent and each tool is also a Keycloak client, and the operator registers each one automatically. + +## MCP + +The [Model Context Protocol](https://modelcontextprotocol.io). An agent uses MCP to call a tool. A +Rossoctl tool uses MCP on the `/mcp` endpoint. + +## MCP Gateway + +A proxy that gives each agent one address for all tools. It adds a prefix to each tool name, to prevent a +conflict. Most authentication in the gateway is not implemented. See +[MCP Gateway](../concepts/experiments/mcp-gateway.md). + +## MCPServerRegistration + +The resource that registers a tool with the MCP Gateway.

It is a proxy between an agent and each external service, which are models, +tools, users and other agents. It runs as a sidecar, as a local proxy or as a gateway. See +[RossoCortex](../concepts/core/cortex.md). + +## Sandbox + +A Kubernetes resource that gives an agent stronger isolation than a pod gives. Rossoctl uses the upstream +agent-sandbox project. See [Sandboxes](../concepts/experiments/sandboxes.md). + +## Shipwright + +The system that Rossoctl uses to make a container image from source code. It needs the `--with-builds` +option. + +## Skill + +A reusable capability that contains instructions, scripts and configuration. The cluster holds it as a +ConfigMap with the label `rossoctl.io/type=skill`. You give a skill to an agent instead of a copy of the +instructions in a prompt. See [Skills](../concepts/experiments/skills.md). + +## Skillberry store + +A registry in the cluster that manages a set of skills. It has plugins that evaluate, improve, remove +duplicates from and examine each skill. The `--with-skills` option installs it. + +## SPARC + +See [Tool call validation](#tool-call-validation). + +## SPIFFE + +[Secure Production Identity Framework For Everyone](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/). +The standard that Rossoctl uses for the identity of a workload. An identity has this form: +`spiffe://{trust-domain}/ns/{namespace}/sa/{service-account}`. + +## SPIRE + +The program that implements SPIFFE. It issues and renews the identity of each workload. The `--with-spire` +option installs it. See [Workload identity](../security/workload-identity.md). + +## SVID + +A SPIFFE Verifiable Identity Document. SPIRE issues one. An X.509 document is for mTLS. A JWT document is +for an HTTP interface. Both are short-lived and SPIRE renews both automatically. + +## Token exchange + +The method that [RFC 8693](https://tools.ietf.org/html/rfc8693) describes. It replaces the token of a user +with a token that is valid only for one target. An agent can therefore act for a user without a credential +of the target, and without more permissions than the user has. See +[Identity and trust](../concepts/core/identity.md). + +## Tool + +A container that uses the MCP protocol. It makes functions, files and prompt templates available to an +agent. See [Deploy a tool](../workloads/deploy-a-tool.md). + +## Tool call validation + +A method that denies a tool call with an invented argument, or with an incorrect choice of tool. The plugin +is `sparc`. See [Tool call validation](../concepts/experiments/tool-validation.md). + +## Tool prune + +A plugin that removes the definition of each tool that an agent does not call. Those definitions are 4 +percent to 20 percent of the prompt on each turn. See +[Cost control](../concepts/experiments/cost-control.md). + +## Tornjak + +A browser interface for SPIRE. It shows the registered workloads and the identity of each one. + +## Trust domain + +The first part of a SPIFFE identity. On a default Kind installation it is `localtest.me`. The `--domain` +option sets it. + +## ztunnel + +The node-level proxy of the Istio ambient mesh. It gives mTLS between workloads. You must restart it after +you suspend a computer for a long period.

A signature lets the platform confirm that the card comes from the workload that +the card describes. A signature is necessary for the strict +[identity binding](../concepts/core/control-plane.md#identity-binding) mode. For the format, see the +section on signatures in the [A2A specification](https://a2a-protocol.org/latest/). + +## The variables that your agent must read + +Rossoctl gives the configuration to your agent in environment variables. Read these variables. Do not +put a fixed value in your code. + +| Variable | Use it for | +| --- | --- | +| `LLM_API_BASE`, `LLM_API_KEY`, `LLM_MODEL` | The address, the key and the name of the model. | +| `MCP_URL` | One MCP address. It is one tool, or the gateway. | +| `MCP_URLS` | More than one MCP address. Separate them with commas. | + +If your agent reads these variables, you can change the model between Ollama, OpenAI and any compatible +endpoint with no change to the code. You can also change between direct tools and the gateway in the +same way. See [Configure a model](../get-started/configure-a-model.md). + +## What you must not do + +**Do not add authentication code.** The RossoCortex sidecar validates each token before the request +reaches your program. When your code runs, the caller is authenticated. + +**Do not hold a credential for a tool.** The sidecar exchanges the token for you. Your agent calls +`http://weather-tool:8080/mcp`, and the sidecar adds a token that is valid only for that tool. Never put +a key that belongs to a tool in your agent. + +**Do not add code to send traces.** The operator configures the trace destination. You can add your own +spans for detail, but the transport is present. + +**Do not open a connection that avoids the proxy.** Traffic that does not pass through RossoCortex is +outside the security model. Read the `HTTP_PROXY` and `HTTPS_PROXY` variables. Most HTTP libraries read +them automatically. + +## How to package the agent + +- Write a `Dockerfile` that produces a container. The container must listen on one HTTP port. +- For a build from source, put the code on GitHub, in a **subdirectory** that contains the `Dockerfile`. + The code must not be in the root directory. The repository must be reachable with the token that you + gave to the installer. +- Do not put a secret in the image. Use an environment variable and a Kubernetes Secret. + +## Frameworks with an example + +| Framework | Notes | +| --- | --- | +| [LangGraph](https://github.com/langchain-ai/langgraph) | Most of the samples use this framework. | +| [CrewAI](https://www.crewai.com/) | For a group of agents with roles. | +| [AG2, formerly AutoGen](https://microsoft.github.io/autogen/) | For agents that hold a conversation. | +| [Llama Stack](https://github.com/meta-llama/llama-stack) | For the ReAct pattern. | +| [BeeAI](https://github.com/i-am-bee/bee-agent-framework) | — | +| Agent programs such as Claude Code | These run behind RossoCortex directly.
