Design constraint + +Every tool visible to a model is an RSS-owned component. + +RSS owns: + +- public tool name and description; +- JSON Schema presented to the provider; +- registry order and enablement; +- argument validation and defaults; +- dispatch by public tool name; +- tool-specific algorithms and result formatting; +- tool-specific error mapping; +- composition of one or more native capabilities. + +Rust owns only generic capabilities and runtime invariants that cannot safely depend on script cooperation. + +Rust must not contain: + +- a built-in list of model-visible tool names; +- model-visible tool descriptions or JSON Schemas; +- an enum with variants such as `ReadFile`, `Patch`, or `Terminal`; +- dispatch branches keyed by public tool names; +- tool-specific argument parsing or response formatting. + +This boundary applies to current tools and future tools. Adding a model-visible tool must normally require an RSS change and tests, with no Rust registry change. + +## 2. Current mismatch + +The current implementation places the six public tools in `src/tools/*`: + +- `registry.rs` owns the built-in ordering, schemas, risk classes and native executor mapping; +- `dispatch.rs` validates public arguments, selects `NativeToolExecutor`, manages execution and shapes `ToolResult`; +- `files.rs`, `terminal.rs` and `process.rs` contain model-visible behavior; +- `rss/agent/main.rss` delegates each call to `agent::tool_dispatch`. + +That structure makes RSS the loop coordinator while Rust remains the actual tool platform.

These names describe native primitives and are never presented to a model. + +Capability APIs are registered under namespaces separate from the agent tools: + +```text +cap::fs_metadata(execution_token, path) +cap::fs_read_range(execution_token, path, offset, limit) +cap::fs_list(execution_token, path, cursor, limit) +cap::fs_write_atomic(execution_token, path, expected_hash, bytes) +cap::process_spawn(execution_token, argv, cwd, env_names, limits) +cap::process_poll(execution_token, process_handle, cursor, limit) +cap::process_write(execution_token, process_handle, bytes) +cap::process_kill(execution_token, process_handle) +cap::artifact_put(execution_token, bytes, metadata) +``` + +The exact host schema uses typed maps/resources supported by pd-vm. Public model tool descriptors never reuse these capability schemas. + +## 4. Execution lifecycle + +### 4.1 Preparation + +RSS receives one provider tool call and validates it against the RSS descriptor. It then calls: + +```text +agent_runtime::tool_prepare(metadata) -> map +``` + +Metadata contains: + +- run ID; +- call ID; +- opaque public tool name; +- canonical argument digest; +- descriptor/registry identity; +- RSS risk classification; +- bounded sanitized summary. + +Rust treats the name as opaque data. `tool_prepare` performs generic checks: + +1. run and parent are active; +2. call ID/name match the durable assistant parent; +3. canonical terminal result is replayed when present; +4. run/tool-call limits permit another call; +5. approval policy permits execution; +6. `tool.started` is committed durably before capability access; +7. a scoped execution token is issued. + +Return shape: + +```json +{ + "kind": "execute", + "execution_token": "opaque", + "deadline_ms": 0 +} +``` + +or: + +```json +{ + "kind": "replay", + "result": {} +} +``` + +### 4.2 Capability use + +Each execution token is bound to: + +- profile/session/run/call identity; +- frozen workspace directory capability; +- absolute deadline and cancellation token; +- approved risk ceiling; +- output/artifact budgets; +- process ownership; +- lifecycle generation. + +A token cannot be reused by another call or after terminal commit. Native capability functions validate the token before every effect. RSS cannot mint or modify one. + +One tool may invoke multiple capabilities. This supports RSS implementations such as `patch`: bounded read, RSS transformation, atomic compare-and-write. + +### 4.3 Completion + +RSS normalizes and bounds the result, then calls: + +```text +agent_runtime::tool_commit(execution_token, result) -> map +``` + +Rust validates token ownership, commits the durable tool result and terminal tool event, closes the execution token, and returns the committed envelope. + +If RSS terminates or panics with an open token, RAII cleanup marks the execution interrupted, cancels owned processes and prevents token reuse. Recovery never repeats an execution that has a canonical durable terminal result. + +## 5. Tool algorithms in RSS + +### 5.1 `read_file` + +RSS validates path, offset and limit; it calls bounded read capability and adds line numbers and pagination metadata. Rust performs path confinement and byte I/O only. + +### 5.2 `search_files` + +RSS owns glob/regex options, pagination, ordering and output formatting. Rust exposes bounded directory iteration and bounded file reads. If performance later requires a native search iterator, it must remain a generic workspace search capability with no model-facing schema or formatting. + +### 5.3 `write_file` + +RSS validates input, reads current metadata/hash when needed and requests atomic replacement. Rust enforces root confinement, expected-hash compare, file mode policy and atomic write mechanics. + +### 5.4 `patch` + +RSS parses replacement/patch input, computes candidate content, checks uniqueness and formats a diff preview/result. Rust only supplies bounded read and atomic compare-and-write. No patch grammar or fuzzy-match strategy remains in Rust. + +### 5.5 `terminal` + +RSS validates command, cwd and user-facing options, then maps them to `cap::process_spawn`. Rust owns process-group creation, environment allowlist, cwd capability, time/output limits and cancellation. + +### 5.6 `process` + +RSS maps public actions to process capability operations and formats logs/status. Rust owns opaque process resources, authorization, bounded buffers, stdin/kill mechanics and cleanup. + +## 6. Registry snapshot and provider contract + +At run admission, Rust invokes the exported RSS registry function using the admitted agent source and non-secret tool policy. The returned descriptor array is: + +1. structurally bounded by Rust; +2. canonicalized deterministically; +3. hashed; +4. stored in the run context as the frozen provider-facing registry snapshot. + +Rust verifies generic limits for count, names, description bytes, schema bytes/depth and duplicate names. It does not supply built-in names, descriptions or schemas. + +The frozen snapshot is sent to every provider request for that run. Resume recompiles/loads the same RSS source and verifies registry identity before continuing. A changed registry requires a new run or an explicit migration contract. + +## 7. Approval boundary + +RSS assigns the requested risk class in each descriptor. Rust policy maps the frozen descriptor identity and risk class to allow/ask/deny. + +Approval records bind: + +- run/call ID; +- registry identity; +- canonical argument digest; +- requested risk class; +- expiry. + +RSS cannot lower risk after approval because `tool_prepare` compares the requested metadata with the frozen descriptor. A capability also checks that its native operation does not exceed the approved ceiling. For example, a read-approved token cannot call a write or process capability. + +## 8. Failure and recovery behavior + +- Invalid RSS arguments fail before `tool_prepare`; no durable started state or native effect occurs. +- A failed durable started commit returns a terminal dispatch error and no execution token. +- A capability error is converted by the RSS tool module into its public error contract, then committed once. +- A failed result commit after a native effect closes the execution token and fails the run; the capability is not repeated in-process. +- Restart inspects durable lifecycle state. Completed/failed/interrupted results replay. An execution left open at process death becomes interrupted through recovery policy and does not automatically repeat mutating effects. +- Process handles are run/call-owned and are cancelled during stop, deadline, source failure or gateway recovery. + +## 9. Security properties + +- Workspace authority originates in Rust admission, never in RSS strings. +- Every path capability resolves beneath the frozen root and resists symlink replacement. +- Every process starts in an authorized cwd with bounded environment, duration and output. +- RSS receives opaque handles/tokens only. +- RSS cannot call capabilities before durable preparation or after completion. +- Capability errors expose bounded neutral messages and no host absolute paths outside the workspace. +- Tool output/artifacts pass through existing secret redaction and byte caps before persistence/publication. +- Generic pd-vm host APIs that bypass these checks are omitted from the production agent catalog. + +## 10. Migration sequence + +1. Add RSS tool contract tests and generic capability interfaces while retaining old dispatch behind a test-only comparison path. +2. Move registry descriptors, ordering, schema validation and fingerprint source into RSS. +3. Implement lifecycle execution tokens and capability risk classes. +4. Migrate read-only file tools and compare exact fixture envelopes. +5. Migrate write/patch tools with atomic compare-and-write tests. +6. Migrate terminal/process tools with process ownership and restart tests. +7. Switch `rss/agent/main.rss` from `agent::tool_dispatch` to `tools::dispatch`. +8. Remove `NativeToolExecutor`, built-in registry entries and public tool-name branches from Rust. +9. Rename surviving generic modules from `tools` to `capabilities`. +10. Run full agent, gateway, Telegram, debug and release gates. + +No compatibility shim remains in production after migration. Durable data compatibility is preserved because public tool names, call IDs, result roles and event contracts remain unchanged. + +## 11. Test contract + +### RSS tests + +- descriptors and schemas for all six tools; +- deterministic registry identity; +- validation defaults and failures; +- dispatch routing; +- exact result envelopes; +- patch/search algorithms; +- terminal/process action mapping; +- provider tool-call to tool-result loop. + +### Rust capability tests + +- token ownership and single-close behavior; +- workspace confinement and symlink races; +- atomic compare-and-write; +- process group cancellation and output caps; +- approval ceiling enforcement; +- durable-before-effect preparation; +- replay and interrupted recovery; +- panic/unwind cleanup. + +### Architecture tests + +- Rust production source contains no built-in public tool registry. +- `src/capabilities` contains no public tool description/schema fixtures. +- `rss/tools` contains all model-visible descriptors. +- adding a fixture-only RSS tool requires no Rust enum/dispatch edit. +- production host catalog excludes unrestricted pd-vm file/process APIs. + +### End-to-end tests + +- real RSS agent loop executes every tool through generic capabilities; +- gateway restart replays canonical tool results without duplicate effects; +- stop/deadline cancels open process capabilities; +- approval blocks capabilities before effect; +- toolset snapshot remains identical across reopen; +- Telegram/API output remains compatible. + +## 12. Acceptance criteria + +1. Every model-visible tool is defined and implemented in `rss/tools`. +2. `rss/agent/main.rss` contains no call to `agent::tool_dispatch`. +3. Rust has no `NativeToolExecutor` or built-in public tool order. +4. Rust exposes generic capabilities and durable lifecycle functions only. +5. Workspace, process, approval, output and cancellation safeguards remain native and mandatory. +6. Existing public tool names and durable message/event contracts remain compatible. +7.

Rust treats the public tool name as opaque metadata. Production Rust code must contain no built-in public tool order, public descriptor/schema fixtures, `NativeToolExecutor`, or dispatch branches keyed by `read_file`, `search_files`, `write_file`, `patch`, `terminal` or `process`. + +The generic lifecycle contract is: + +```text +agent_runtime::tool_prepare(metadata) -> execute token | durable replay +cap::* (execution_token, ...) -> bounded native capability result +agent_runtime::tool_commit(execution_token, result) -> committed envelope +``` + +`tool_prepare` commits durable started state before issuing a capability token. Every capability validates run/call ownership, risk ceiling, workspace, deadline and cancellation. RSS cannot mint, modify or reuse execution tokens. `tool_commit` durably closes the call.

Device code, user code, authorization code, PKCE verifier, PKCE state, request bodies and transient errors never enter this file. +- `id_token` is omitted unless a provider requires it for future runtime behavior. The initial Codex path does not persist it. +- `account_id` is derived from the validated access-token JWT claim `https://api.openai.com/auth.chatgpt_account_id`; it is metadata, never trusted as authorization by itself. +- Refresh-token rotation increments `generation`. Writers must compare the generation observed before the network call and re-read under the auth lock before commit. +- Terminal refresh errors set `status: reauth_required` without deleting the last token pair. Transient network/5xx/429 errors leave credential state active and return a retryable typed error. + +### 2.4 File security and concurrency + +- Create home directory with Unix mode `0700`; create `auth.yaml`, lock and replacement files with `0600`. +- Reject symlink auth files and unsafe parent traversal; use no-follow/openat-style checks where supported. +- Read file through a bounded byte cap before parsing YAML. +- Save using same-directory exclusive temporary file, flush, fsync, atomic rename and parent-directory fsync. +- Protect read-modify-write using an in-process mutex plus cross-process lock. +- Never serialize auth structs through `Debug`; implement redacted summaries. +- Windows tests verify atomic replacement and best available ACL/file handling without claiming POSIX mode guarantees. +- Corrupt YAML is moved or copied to a timestamped `.corrupt` artifact only after a bounded read; startup/login returns a typed error and never silently starts from an empty credential set. + +## 3. Rust OAuth boundary + +All new OAuth code lives in this repository. No OAuth type, host function or provider special case is added to `pd-vm` or any other RustScript core crate. + +### 3.1 Library modules + +Create: + +```text +src/auth/mod.rs +src/auth/config.rs +src/auth/store.rs +src/auth/oauth.rs +src/auth/host.rs +src/auth/pkce.rs +src/auth/token.rs +``` + +Core public types: + +```rust +pub struct AuthStore; +pub struct CredentialId(String); +pub struct OAuthProviderConfig; +pub struct OAuthTokenSet; +pub struct OAuthClient; +pub struct OAuthSession; +pub enum OAuthFlowKind { AuthorizationCodePkce, DeviceCode } +pub enum AuthStatus { Active, ReauthRequired, Disabled } +pub enum OAuthErrorCode; +``` + +`OAuthClient` receives an injected clock, HTTP transport, browser opener and loopback listener factory so tests never contact live providers. + +### 3.2 Generic native operations + +Expose library functions and matching RSS host functions under an `oauth::` namespace: + +```text +oauth::request(auth_id, operation, payload) -> typed response +oauth::save_tokens(auth_id, token_response) -> credential metadata +oauth::access_token(auth_id) -> short-lived access envelope +oauth::status(auth_id) -> redacted metadata +oauth::delete(auth_id) -> typed result +``` + +`operation` is a symbolic operation configured by Rust (`device_start`, `device_poll`, `token_exchange`, `refresh`). RSS cannot pass an arbitrary URL, HTTP method or Authorization header. Rust resolves endpoint, method, body encoding, timeout and allowed authority from `config.yaml`. + +`oauth::request` returns bounded provider data: + +```json +{ + "ok": true, + "status": 200, + "body": {}, + "retry_after_ms": null +} +``` + +The host enforces: + +- HTTPS remote endpoint and configured authority. +- bounded response body, JSON depth/key/string limits and deadline. +- cancellation propagated from the owning CLI/run. +- redaction of token-shaped response fields in logs and errors. +- no durable event publication for raw OAuth payloads. + +`oauth::save_tokens` accepts a provider response only from the active in-memory OAuth session. It validates access token, optional refresh rotation, token type and expiry before calling `AuthStore`. + +`oauth::access_token` returns only access token, token type, expiry and derived account ID to the ephemeral provider invocation. It never returns refresh token to RSS. + +### 3.3 Generic authorization-code OAuth flow + +Rust implements a reusable Authorization Code + PKCE S256 flow: + +1. Generate cryptographically random verifier and state. +2. Build authorization URL from the selected provider config. +3. Bind a random loopback port on `127.0.0.1` and accept one bounded callback. +4. Open the browser when available. +5. Validate exact state and single-use callback session. +6. Exchange code using form encoding and the configured token endpoint. +7. Persist validated tokens through `AuthStore`. +8. On SSH/headless systems, print the URL and accept a pasted callback URL/code through the CLI without weakening state/PKCE checks. +9. Cancel and remove all transient state on timeout, Ctrl-C or callback error. + +Generic flow configuration supports provider-specific scopes and additional public authorization parameters through a strict allowlist. Client secrets are outside the initial public-client scope. + +### 3.4 Generic refresh flow + +Rust owns token refresh for every OAuth provider: + +1. Read credential and generation. +2. If access token remains valid beyond `refresh_skew_seconds`, return it. +3. Serialize refresh per credential ID; re-read after acquiring the lock. +4. POST `grant_type=refresh_token` with client ID and current refresh token. +5. Require a new access token. +6. Preserve old refresh token if the response omits one; atomically replace it when rotated. +7. Update absolute expiry from `expires_in`, with bounded clock-skew handling. +8. Classify `invalid_grant`, `invalid_token`, HTTP 401/403 and consumed refresh token as `reauth_required`. +9. Classify 429 using `Retry-After`; keep existing credential active and expose a retryable/quota error. +10. Treat transport timeout and 5xx as retryable; never overwrite a valid credential with a partial response. + +Two gateway processes racing a single-use refresh token converge through the auth file lock and generation check. The later process adopts the newer generation rather than replaying the old refresh token. + +## 4. RSS Codex device login + +Create: + +```text +rss/auth/codex_device.rss +rss/auth/types.rss +``` + +The Codex-specific state machine remains in RSS and uses only the generic Rust host functions. + +### 4.1 State sequence + +1. Call `oauth::request(auth_id, "device_start", {client_id})`. +2. Parse `user_code`, `device_auth_id` and `interval`; reject missing/wrong-type/oversized fields. +3. Emit a sanitized CLI instruction containing `https://auth.openai.com/codex/device` and the user code. The device auth ID remains internal. +4. Poll `device_poll` with `{device_auth_id, user_code}` until authorization, cancellation or a 15-minute absolute deadline. +5. Treat HTTP 403/404 as pending for this provider. +6. Honor configured minimum interval and bounded 429 `Retry-After`; no tight polling. +7. Parse `authorization_code` and `code_verifier` from the successful poll response. +8. Call `token_exchange` using authorization-code grant, configured redirect URI and verifier. +9. Call `oauth::save_tokens`; report only redacted credential metadata. +10. Clear all transient values before return on success, rejection, cancellation or timeout. + +### 4.2 Required RSS tests + +Use a fake native OAuth host and fixture responses to cover: + +- happy path and exact operation order. +- pending 403/404 followed by success. +- 429 backoff and absolute deadline. +- cancellation during wait. +- malformed start, poll and exchange responses. +- exchange with missing access token. +- refresh token present/absent in initial exchange. +- no raw token/device auth ID in events, snapshots or rendered output. +- no direct `http::*` call and no hard-coded credential persistence in the RSS module. + +## 5. CLI auth and config UX + +Refactor the current single-purpose argument parser without breaking legacy invocation. + +Commands: + +```text +rustscript-agent auth login openai-codex +rustscript-agent auth login +rustscript-agent auth status [provider] +rustscript-agent auth logout +rustscript-agent config path +rustscript-agent config check +rustscript-agent run --script ... +``` + +Legacy `rustscript-agent --script ...` remains an alias for `run` during migration. + +Files likely to change: + +```text +src/bin/rustscript-agent.rs +src/bin/rustscript-agent-gateway.rs +src/config.rs +src/lib.rs +``` + +CLI acceptance criteria: + +- Login writes only `auth.yaml`; provider/model selection writes only `config.yaml`. +- Status output never prints token prefixes or lengths. +- Logout removes one named credential atomically and leaves unrelated credentials unchanged. +- `config check` validates config/auth references and reports missing, disabled or reauth-required credentials without printing secrets. +- Device login works over SSH without trying to bind a publicly reachable callback. +- Ctrl-C exits with a typed cancellation and leaves no partial credential entry. + +## 6. Runtime provider integration + +### 6.1 Credential resolution + +At run admission, freeze only the credential ID and provider configuration hash. Immediately before each real provider request: + +1. Resolve the named credential through `AuthManager`. +2. Refresh when required. +3. Construct an ephemeral provider transport profile. +4. Invoke the RSS provider adapter. +5. Drop the token-bearing profile after the call. + +Do not put access/refresh tokens in: + +- `RunContext` or its SQLite JSON. +- provider fingerprint input. +- `model.requested` / `model.completed` event payloads. +- assistant/tool messages. +- metrics labels. +- artifact files. +- panic/error strings. + +The durable provider fingerprint uses model, protocol, sanitized provider options and canonical messages. Credential ID and token generation are excluded so a refresh does not change logical request identity. + +### 6.2 Codex Responses transport + +Implement the Codex inference path required by the new login: + +```text +rss/llm/openai_responses.rss +rss/llm/harness.rss +src/runtime/rss_runner.rs +``` + +Required request behavior: + +- Base URL defaults to `https://chatgpt.com/backend-api/codex` from config. +- Transport uses the Responses protocol expected by the Codex backend. +- Rust derives `ChatGPT-Account-ID` from the access-token JWT claim and exposes it only to the ephemeral adapter profile. +- Set the Codex-compatible `originator` and `User-Agent` headers from trusted native configuration, never from user/RSS payload. +- Authorization header is built at the final transport boundary. +- 401 triggers one refresh-and-retry for the same logical provider step; no duplicate `model.requested` row or turn count. +- 429/quota remains distinct from expired authentication. +- Streaming and cancellation preserve the existing durable provider contract. + +Tests use a local TLS/HTTP fixture or injected transport; no live OpenAI call belongs in CI. + +## 7. Bundled coding agent default + +Change gateway startup so a production binary can run without a source checkout: + +- Embed `rss/agent/main.rss` and its imports at build time or package them as verified resources beside the binary. +- `agent.source: bundled:coding` is the default. +- `agent.source: file:/absolute/path.rss` enables custom source after size/hash/compile validation. +- Keep `RUSTSCRIPT_AGENT_SCRIPT` as a deprecated migration override only. +- Compile the selected source at startup and expose its hash in redacted health metadata. +- Startup fails before binding when the source or provider/auth reference is invalid. + +Tests prove the installed binary can start from a directory containing no repository source files. + +## 8. Explicit workspace selection + +Add config and API fields for workspace selection: + +- `workspaces.allowed_roots` defines canonical permitted roots. +- `workspaces.default` is optional and must lie under an allowed root. +- `POST /api/runs` accepts a workspace path or configured workspace name. +- Telegram session commands can select/status a workspace; the selected canonical path is durably attached to the session. +- Admission resolves the path once, opens the directory capability and freezes it into `RunLimits`. +- Symlink replacement after admission cannot escape the opened root. +- A request cannot select process cwd implicitly when no default is configured. + +Existing file/process confinement tests become parameterized across default, named, denied, symlink and reopen cases. + +## 9. Approval execution chain + +Wire existing approval persistence into the serial tool dispatcher: + +1. `read_file` and `search_files` follow configured read policy. +2. `write_file` and `patch` default to `ask`. +3. `terminal` and `process` default to `ask`. +4. Before `tool.started` or native effect, persist `approval.requested` with canonical call hash and expiry. +5. Expose approve/reject through HTTP and Telegram. +6. Resume the same durable tool call after approval; revalidation must detect changed name/arguments/parent. +7. Rejection, expiry, stop and restart produce one typed terminal tool result with no native effect. +8. Approval records contain sanitized summaries, never complete file contents, command output or credentials. + +The durable replay rule remains: an already completed/failed/interrupted canonical result bypasses both approval and native effect. + +## 10.

Delivery contract + +The finished system must satisfy all of these statements: + +1. Every model-visible tool is defined and implemented in `rss/tools/*`. +2. RSS owns public tool schemas, validation, dispatch, algorithms and result formatting; Rust owns only generic confined capabilities and lifecycle enforcement. +3. Rust production code contains no `NativeToolExecutor`, built-in public tool list/schema or public-name dispatch branches. +4. `rss/agent/main.rss` calls RSS tool dispatch directly; `agent::tool_dispatch` is removed. +5. A new RSS-only tool can be registered and executed without editing Rust dispatch code. +6. A fresh user can create config, run Codex device login, select a workspace and start the bundled coding agent without editing RSS or injecting a test provider. +7. OAuth access tokens refresh automatically and atomically; refresh-token rotation survives concurrent gateway/CLI access. +8. `config.yaml` contains no credentials; `auth.yaml` contains no behavior policy. +9. Codex device-login policy is implemented in RSS; generic OAuth transport, PKCE, storage and refresh are implemented in Rust inside `rustscript-agent`. +10. No OAuth functionality is added to RustScript core. +11. Raw auth material is absent from durable agent state, events, metrics, logs, artifacts and error text. +12. Mutating tool effects respect workspace and approval policy. +13. Long sessions compact durably and reopen without losing tool parent relationships. +14. Full debug and release suites pass from the final integrated commit. + +## 14. Main risks and chosen trade-offs + +- **RSS tool logic still needs native safeguards:** every effect requires a Rust-issued execution token. Production host catalogs exclude unrestricted file/process APIs that could bypass workspace, approval, deadline or durable lifecycle checks. +- **Migration can change output contracts:** each tool migrates against exact old/new fixtures before old native dispatch is removed. Public tool names and durable message/event shapes remain compatible. +- **YAML contains plaintext tokens:** initial scope uses strict local-file protection and atomic writes. OS keychain integration may be added later behind the same `AuthStore` trait without changing RSS or provider contracts. +- **Codex device endpoints are provider-specific:** endpoint paths and response interpretation stay in RSS/config; Rust exports symbolic confined operations and generic token persistence. +- **Refresh tokens may rotate on every use:** per-credential serialization plus generation revalidation is mandatory from the first release. +- **Codex backend needs trusted headers:** account ID is derived natively from JWT; originator/User-Agent are trusted config constants and cannot come from a run request. +- **Multiple auth entries:** named credentials are supported now; automatic pool rotation remains outside this plan. +- **Environment migration:** behavior settings move to `config.yaml`; environment remains only for selecting the agent home during bootstrap and for temporary compatibility reads. diff --git a/rss/agent/main.rss b/rss/agent/main.rss index 2a9644a..88f320b 100644 --- a/rss/agent/main.rss +++ b/rss/agent/main.rss @@ -1,77 +1,15 @@ -// A5 serial loop policy skeleton (pure decision policy; no provider -// transport, no storage, no tool runner). +// Serial provider/tool agent loop. // -// The exported `run(context)` is a state-machine step function: ONE typed -// context map in, ONE discriminated decision map out.
