/home/byk/Code/opencode-lore-v2/packages/gateway/src/config.ts:1172-1207 defines ProjectPathSource = "header" | "inferred" | "cwd" and ProjectPathResult with required path, source, optional normalized gitRemote, and optional overrodeHeaderPath carrying a rejected stale X-Lore-Project path. UNATTRIBUTED_PREFIX re-exports UNATTRIBUTED_PROJECT_PREFIX; unattributedBucketPath(sessionID) returns ${UNATTRIBUTED_PREFIX}/${sessionID}; isUnattributedPath aliases isUnattributedProjectPath./home/byk/Code/opencode-lore-v2/packages/gateway/src/config.ts:1212-1275 documentation says project resolution checks X-Lore-Project, inferred system-prompt path, then process.cwd(), but implementation gives authoritative inferProjectPathDetailed(systemPrompt) the strongest priority. An authoritative inference overrides a conflicting header and returns overrodeHeaderPath; an agreeing/absent header yields source "inferred"; without authoritative inference, a valid header yields source "header"; otherwise it falls back to discoverWorkspaceRoot(process.cwd()) with source "cwd". Weak generic /home|/Users matches are treated as absent because trusting embedded paths could cause destructive cross-project self-heal merges./home/byk/Code/opencode-lore-v2/packages/gateway/src/config.ts:1281-1335 limits X-Lore-Git-Remote to 512 characters and X-Lore-Project to 1024. Both extractors remove [\x00-\x1f\x7f] control characters and trim whitespace; extractGitRemoteHeader() returns normalizeRemoteUrl(sanitized), while extractProjectHeader() additionally requires an absolute / path and strips trailing slashes./home/byk/Code/opencode-lore-v2/packages/gateway/src/config.ts:1341-1348 implements parsePort(value, fallback) using Number.parseInt(value, 10) and accepts ports from 0 through 65535; missing values use the fallback, while NaN, negative, or above-65535 values log warning: invalid port "${value}", using default ${fallback} and use the fallback./home/byk/Code/opencode-lore-v2/packages/core/test/fetch-interceptor-install.test.ts is a 348-line Vitest end-to-end suite for installFetchInterceptor and interceptUrlForProtocol, using gateway http://127.0.0.1:3207, session sess-123, and project /home/me/proj; its stubbed fetch captures URL/init and returns HTTP 200 with body "ok".installFetchInterceptor — end-to-end routing Path 1 has exactly 6 tests in order: 1. Anthropic https://api.anthropic.com/v1/messages rewrites to gateway /v1/messages with upstream base https://api.anthropic.com; 2. Codex https://chatgpt.com/backend-api/codex/responses rewrites to /v1/codex/responses with upstream base https://chatgpt.com/backend-api; 3. OpenAI chat preserves authorization: Bearer sk-test, injects x-lore-session-id: sess-123 and x-lore-project: /home/me/proj, and exposes auth to onRequestHeaders; 4. a request already targeting gateway /v1/messages exposes Bearer direct without another rewrite; 5. Anthropic requests preserve and observe both authorization: Bearer secondary and x-api-key: primary-key; 6. the original JSON body is forwarded intact.installFetchInterceptor — end-to-end routing Path 1 also verifies OpenRouter https://openrouter.ai/api/v1/chat/completions maps to gateway /v1/chat/completions while setting x-lore-upstream-url: https://openrouter.ai/api./v2/chat/completions plus { model, messages } is detected as OpenAI and maps to /v1/chat/completions with upstream base https://api.example.com/v2; 2. /llm/messages plus Anthropic-shaped { model, system, messages } maps to /v1/messages with base https://proxy.example.com/llm; 3. /custom/responses plus { model, input } maps to /v1/responses with base https://api.example.com/custom; 4. OpenAI shape is detected from a TextEncoder-produced Uint8Array; 5. { model: "gpt-4", prompt: "hi" } is unrecognized and passes through untouched with no x-lore-upstream-url; 6. an unreadable ReadableStream body with duplex: "half" is either passed through untouched or “never rewritten to gateway.”x-lore-upstream-path — original endpoint preservation (#1052) section has exactly 4 tests in order: 1. GitHub Copilot’s bare /chat/completions maps to gateway /v1/chat/completions, uses upstream base https://api.githubcopilot.com, and preserves x-lore-upstream-path: /chat/completions; 2. standard OpenAI preserves /v1/chat/completions; 3. OpenRouter preserves the full prefixed pathname /api/v1/chat/completions to avoid doubling /api; 4. Codex preserves /backend-api/codex/responses.https://registry.npmjs.org/some-package remains untouched, and local LLM URL http://localhost:8000/v1/messages is not intercepted.interceptUrlForProtocol has exactly 6 tests in order: 1. "openai" maps /v2/chat/completions to gateway /v1/chat/completions, base https://api.example.com/v2, and full original path /v2/chat/completions; 2. Copilot’s bare path yields base https://api.githubcopilot.com and path /chat/completions; 3. "anthropic" maps /llm/messages to /v1/messages with base https://proxy.example.com/llm; 4. "openai-responses" maps /custom/responses to /v1/responses with base https://api.example.com/custom; 5. query ?stream=true is preserved; 6. unknown /weird/path falls back to origin https://api.example.com./home/byk/Code/opencode-v2-pilot/packages/core/src/session/generate.ts:17-67 defines SessionGenerate.Error as AgentNotFoundError | Instructions.InitializationBlocked | SessionRunnerModel.Error | AIError and generate({ session, prompt }), which waits for plugin activation, selects session context, resolves the model, previews history using provider provenance or "local", builds a base transcript, appends any history.instructionUpdate as a system message and the prompt as a user message, prepares a "generate" request, logs session/provider/model IDs and usage, calls llm.generate(), returns response.text, and provides the supplied session through Instance.Service./home/byk/Code/opencode-v2-pilot/packages/core/src/session/title.ts uses MAX_LENGTH = 100, MAX_CONTEXT_LENGTH = 8_000, and MAX_FIRST_MESSAGE_LENGTH = 2_000; truncate() shortens overlong titles to 97 characters plus ..., and isUntitled() delegates to isExactRootFallback() using title and creation epoch milliseconds./home/byk/Code/opencode-v2-pilot/packages/core/src/session/title.ts:48-99 prepares title generation with kind "title", the title agent’s optional system prompt, one user message, and contextHooks: false; streams text deltas, marks provider errors or caught AI.Error as failure, accumulates step usage with model cost, publishes SessionEvent.UsageRecorded with source "title" even on interruption, and selects the first non-empty trimmed output line./home/byk/Code/opencode-v2-pilot/packages/core/src/session/title.ts:101-149 generates only when the session and first user message exist. For retitling, input contains Original request:\n plus up to 2_000 characters of the first request and a bounded recent transcript of later user text and assistant text parts, keeping the tail within 8_000 characters; context-read failure falls back to the first user text. It tries the selected title model, then the primary model only when the refs differ; publication uses expected bus sequence latestSequence + 1 and aborts stale/concurrent renames through the titleChanged symbol./home/byk/Code/opencode-v2-pilot/packages/core/src/session/context.ts:95-119 implements selectTitle(session): fetch hidden agent ID "title"; resolve the session’s primary model if possible; use the title agent’s explicit model when configured, otherwise the provider’s small model; choose the explicit variant or the first supported variant from ordered MINIMAL_REASONING_VARIANTS = ["none", "minimal", "low"]; resolve that preferred model and fall back to the primary; return { agent, primary, selected }, or nothing when no selection exists./home/byk/Code/opencode-v2-pilot/packages/core/src/session/context.ts:121-176 select(sessionID) dies on a missing session, interrupts on location directory/workspace mismatch, flushes MCP tools, selects the agent, raises AgentNotFoundError if unavailable, then loads tools, built-ins, discovery, skills, references, MCP instructions, and instruction entries with unbounded concurrency. It combines instructions in that exact order and returns session, agent, instructions, and tools; load() resolves the model and maps runner-history entries to messages./home/byk/Code/opencode-v2-pilot/packages/core/src/plugin/agent.ts:26-69 title-agent output must be one line, at most 50 characters, contain no explanation, use the same language as the user, be grammatical, preserve exact technical terms/numbers/filenames/HTTP codes, omit articles the, this, my, a, and an, avoid assuming the tech stack, and output only a title rather than answering questions or using tools."read tool", "bash tool", "edit tool")."Analyzing"."summarizing" or "generating"."hello", "lol", "what's up", or "hey" should become intent/tone titles such as Greeting, Quick check-in, Light chat, or Intro message, rather than a refusal or complaint./home/byk/Code/opencode-v2-pilot/packages/core/src/plugin/agent.ts:58-68 gives 10 title mappings in order: 1. "debug 500 errors in production" → Debugging production 500 errors; 2. "refactor user service" → Refactoring user service; 3. "why is app.js failing" → app.js failure investigation; 4. "implement rate limiting" → Rate limiting implementation; 5. "how do I connect postgres to my API" → Postgres API connection; 6. "best practices for React hooks" → React hooks best practices; 7. "@src/credential.ts can you add refresh token support" → Credential refresh token support; 8. "@utils/parser.ts this is broken" → Parser bug fix; 9. "look at @config.json" → Config review; 10. "@App.tsx add dark mode toggle" → Dark mode toggle in App./home/byk/Code/opencode-v2-pilot/packages/core/src/plugin/agent.ts:71-81 summary output must read like a pull-request description in first person, be 2-3 sentences maximum, describe changes rather than process, omit tests/builds/validation and explanations of what the user requested, and add no new questions. If the conversation ends with an unanswered question, the summary preserves that exact question./home/byk/Code/opencode-v2-pilot/packages/core/src/plugin/agent.ts:83-153 configures 5 agents: 1. default agent renamed Build, mode "primary", with question permission allowed; 2. general renamed General, mode "subagent", denying question and subagent actions; 3. explore renamed Explore, mode "subagent", uses PROMPT_EXPLORE, supports quick/medium/very-thorough codebase searches, denies all by default but allows grep, glob, webfetch, websearch, and read, asks before .env/.env.* and external-directory reads, allows .env.example, and denies subagents; 4. compaction renamed Compaction, mode "primary", hidden; 5. title and summary are hidden primary agents using PROMPT_TITLE and PROMPT_SUMMARY respectively, with all actions denied.PROMPT_EXPLORE describes a file-search specialist that uses Glob for broad patterns, Grep for regex content search, and Read for known paths; adapts to requested thoroughness, returns absolute paths, avoids emojis, and must not create files or run state-modifying bash commands.
