Backward Compatibility — sandbox.enforce defaults to false +**Risk:** Existing users have `sandbox.enabled: false` and tools run on host. If we default `enforce` to `true`, all high-risk tools break. +**Mitigation:** `enforce` defaults to `false`. Only new installs via the updated wizard get `enforce: true`. Document migration path. + +### 2. Skill permissions are optional +**Risk:** Existing skills have no `permissions` block. If we enforce strictly, they lose all tool access. +**Mitigation:** When `permissions` is `undefined`, the skill context is NOT applied to ToolPolicy (only applies when `skillPermissions` is set on context). Skills without permissions work as before — they just don't get per-skill isolation. + +### 3. Injection guard false positives +**Risk:** Legitimate tool arguments might match injection patterns (e.g., a user asking "ignore previous search results and try again"). +**Mitigation:** The guard forces confirmation (not outright denial). Users can approve the action. Audit log captures the detection for review. + +### 4. ContentProvenance on MessageContentPart is optional +**Risk:** Not all code paths set provenance. Old messages in SQLite history lack provenance. +**Mitigation:** Provenance is `optional` (type-safe). The injection guard checks for untrusted content presence but doesn't require all messages to be tagged. Tagging is additive. + +### 5. SecretStore is additive, not mandatory +**Risk:** Ripping out `process.env` access from all tools is a massive change. +**Mitigation:** SecretStore is opt-in. Tools that already use process.env continue to work. New tools and skill-scoped secrets use SecretStore. Migration happens incrementally. + +### 6. HookEngine.requestConfirmation signature extension +**Risk:** Adding an optional `reason` parameter could break existing callers or implementers. +**Mitigation:** The parameter is optional with a default. Existing code passes 2 args and continues to work. + +### 7. Redaction performance in high-throughput audit logging +**Risk:** Recursive redaction on every audit event could add latency. +**Mitigation:** Redaction only processes strings (fast). Known secrets list is typically small (<50 entries). The audit logger already filters by level, so most events are skipped entirely. + +### 8. Config schema changes require Zod migration +**Risk:** Adding `enforce` and `host_mode_allowed` to sandbox schema could break strict config validation. +**Mitigation:** Both fields have `.default()` values. Existing configs without these fields parse fine. Zod handles missing fields via defaults. diff --git a/docs/plans/2026-02-15-credential-system-v2-api-and-oauth-checklist.md b/docs/plans/2026-02-15-credential-system-v2-api-and-oauth-checklist.md new file mode 100644 index 0000000..ea5c0b2 --- /dev/null +++ b/docs/plans/2026-02-15-credential-system-v2-api-and-oauth-checklist.md @@ -0,0 +1,253 @@ +# Credential System v2 (API + OAuth/token) — Implementation Checklist + +**Date:** 2026-02-15 + +**Parent roadmap:** `docs/plans/2026-02-15-openclaw-gap-roadmap.md` + +**Goal:** Close the gap item "OAuth subscription auth" by supporting **both** API-key credentials and OAuth/token-based credentials (provider-specific) with consistent UX, per-tier control, and deterministic resolution. + +## Scope Summary + +- Add `auth_mode` **per tier** (default/fast/complex/local and any `local_providers` entries). +- Keep backward compatibility with existing `use_oauth` behavior. +- Add stored credential support where it currently doesn't exist: + - OpenAI: stored API key (OAuth already exists) + - Anthropic: stored auth token (API key already exists) +- Improve doctor output to surface which auth sources are present (without revealing secrets). + +Non-goals (explicitly out of scope for this checklist): + +- Inventing an Anthropic OAuth device flow. +- Building new provider integrations (Vercel/MiniMax/etc.). + +## Current Baseline (important constraints) + +- OpenAI OAuth uses the ChatGPT/Codex backend endpoint (SSE) and currently **does not support tools** on that path. + - Source: `src/models/openai.ts` +- Anthropic supports `apiKey` and `authToken` in `AnthropicClientConfig`. + - Source: `src/models/anthropic.ts` +- Stored credentials live at `~/.config/flynn/auth.json`. + - Source: `src/auth/openai.ts`, `src/auth/anthropic.ts` + +## Design Decisions + +### 1) New config field: `auth_mode` + +Add `auth_mode` to the per-tier model config: + +- `auto` (default) +- `api_key` +- `oauth` + +`oauth` is interpreted as "OAuth/token mode" (provider-specific).
