OpenCode determines model context windows by reading limit.context from
opencode.json model entries. The provider was not emitting this field,
so all OmniRoute models appeared with an unknown (0) context window
in OpenCode, preventing proper compaction and overflow detection.
- Add limit.context to OpenCodeModelEntry interface
- Add OMNIROUTE_DEFAULT_MODEL_CONTEXT_LENGTHS map (200K Claude / 1M Gemini)
- Include limit.context when generating model entries
- Extend fetchLiveModels to capture context_length from /v1/models
- 5 new tests covering context length coverage, JSON serialisation,
unknown model fallback, and live model fetch
Closes#2481
Error message sanitization (Hard Rule #12):
- claude-auth/export, codex-auth/export, gemini-cli-auth/export routes: replace
raw err.message with sanitizeErrorMessage() from open-sse/utils/error.ts
- imageGeneration, musicGeneration, videoGeneration handlers: import
sanitizeErrorMessage and replace all err.message in return values
- veoaifree-web executor: replace raw upstream response data in errResp() calls
with static strings
OAuth callback page (callback/page.tsx):
- Remove useSearchParams/Suspense dependency that caused hydration failures in
popup windows navigating back from Google OAuth (COOP header severs opener)
- Use window.location.search directly in useEffect with three send methods:
postMessage, BroadcastChannel, localStorage
- Fix postMessage target from "*" to window.location.origin (semgrep finding)
- Move setCurrentUrl call to manual-only branch to avoid unnecessary renders
copilot-web executor:
- Move accessToken from WebSocket URL query string to Authorization header
(avoids credential exposure in server logs)
- Add MAX_POOL_SIZE=100 cap to sessionPool with LRU eviction of oldest entry
CodeQL ReDoS fixes (js/polynomial-redos #233-240):
- Replace while(s.endsWith("/")) s=s.slice(0,-1) pattern (O(n²) allocations)
with index-based loop (O(n) time, single final slice) in:
bin/cli/api.mjs, all 6 cli-helper config generators, opencode-provider
Gemini OAuth:
- mapTokens: add idToken field to fix "missing id_token" export error
- Replace replace(/\/+$/, "") with explicit while-endsWith loop to avoid
polynomial backtracking on inputs with repeated trailing slashes
(CodeQL js/polynomial-redos #233-240, 8 alerts):
- @omniroute/opencode-provider/src/index.ts (normalizeBaseURL)
- bin/cli/api.mjs (stripTrailingSlash)
- src/lib/cli-helper/config-generator/{claude,cline,codex,continue,
kilocode,opencode}.ts (6 generators with identical pattern)
- tests/live/deepseek-web-live.test.ts: assert hostname via URL parsing
instead of String.includes() so the check is exact-match rather than
substring (CodeQL js/incomplete-url-substring-sanitization #241).
Alert #242 (Array.prototype.includes against fixed needle constant
OPENWEBUI_PARAGRAPH_ANCHORS) dismissed as CodeQL false-positive — not a
URL sanitization callsite.
The 1.0.0 release of the package was broken end-to-end:
1. index.js re-exported from "./index.ts" — Node can't import .ts at runtime,
so any consumer who `npm install`ed the package got ERR_UNKNOWN_FILE_EXTENSION.
2. The emitted provider shape did not match the OpenCode schema
(https://opencode.ai/config.json). It used a custom `{id, name, npm, options, auth}`
instead of the schema's `{npm: "@ai-sdk/openai-compatible", name, options, models}`.
3. README told users to pass `baseURL: "http://localhost:20128/v1"` but the code
appended `/v1` again — every request would 404 at `/v1/v1/...`.
4. No build step, no LICENSE file, no repository/author/engines fields, no tests.
This rewrite:
- Moves source under `src/`, adds a tsup build emitting CJS + ESM + .d.ts.
- `createOmniRouteProvider` now returns a schema-valid entry with
`npm: "@ai-sdk/openai-compatible"` + `models: Record<string, { name }>`.
- Adds `buildOmniRouteOpenCodeConfig` for full-document scaffolding.
- `normalizeBaseURL` deduplicates trailing `/` and `/v1`, accepts both forms,
and rejects malformed URLs and empty inputs.
- 13 unit tests covering URL normalisation, input validation, default model
catalog, custom models + labels, dedup/trim behaviour, and JSON round-trip.
- Adds LICENSE, full package.json (repository, engines, scripts, exports),
.gitignore, .npmignore, tsconfig.json, and a comprehensive README.
- Resets version to 0.1.0 to signal the pre-1.0 reset (1.0.0 was never on npm).
Documentation:
- New `docs/frameworks/OPENCODE.md` covering both integration paths (CLI vs npm),
URL normalisation, auth modes, troubleshooting, and runtime flow.
- README.md links the package and points to the new doc.
- CHANGELOG entry under Unreleased > Changed.
