Fourth Phase 2 implementation D-day. Closes ADR 0007 § 10 acceptance criterion #9 (bootstrap workflow must be reproducible without manual file editing) by shipping a minimal keygen CLI per § 9.1. Phase 2 functional scope is complete with this D-day — remaining work is Phase 2 close → v0.2.0 (maintainer-triggered, explicit per CLAUDE.md release_kit.phase_close_trigger). NEW bin/olp-keys.mjs (~250 lines): subcommand CLI keygen [--owner|--name=X|--tier=guest|owner|--providers=csv|--force] Creates a key + prints plaintext token to stdout ONCE; manifest stores only SHA-256 hash. --force revokes existing owner keys before creating the new owner (ADR § 9.3 recovery flow). list [--owner-only|--include-revoked] Lists keys with token_hash redacted. revoke --id=<key-id> Marks the key's revoked_at; idempotent (already-revoked → no-op + status message); missing id → exit 2. Common flag: --olp-home=<path> overrides ~/.olp/ (defaults to OLP_HOME env then ~/.olp/). package.json bin field "bin": { "olp-keys": "./bin/olp-keys.mjs" } so npx olp-keys ... resolves. Also "scripts": { "olp-keys": "node bin/olp-keys.mjs" } for npm run. Module shape (testability) Exports runCli(argv, { out, err }) so tests invoke with synthetic argv + IO writers (no process spawn). Main guard auto-runs when invoked as entrypoint. Plaintext token discipline (ADR § 5 + § 9.1) Plaintext printed exactly once on stdout. Never logged, never written to manifest, never written to audit. Operators capture immediately; lost → --force revoke + regenerate. --force async correctness cmdKeygen is async and awaits each revokeKey (which is async — acquires per-key write lock per § 6.4). Sequence: revoke each existing owner manifest atomically → then createKey for new owner. Avoids race where create-new runs before revoke-old completes. TESTS — Suite 22, +20 (524 → 544): 22a-1..5: parseArgv unit (--flag=value, --flag value, boolean, mixed positional) 22b-1..5: keygen (owner default, name+providers, missing-name error, invalid-tier error, --force revoke-then-create with isolation tmpdir) 22c-1..3: list (empty, populated with token_hash-redaction check, --owner-only filter) 22d-1..4: revoke (valid id, idempotent re-revoke, missing-id error, nonexistent-id error) 22e-1..3: top-level CLI (--help / no args / unknown subcommand exit codes) DOCUMENTATION: - AGENTS.md: lib/keys.mjs marker promoted to ✅; new bin/olp-keys.mjs entry. Implementation-status-note + shipped-set updated. - README.md: Implementation Status row added for bin/olp-keys.mjs; Known limitations note rewritten to "Phase 2 functional scope complete; close pending"; new Bootstrap workflow section with copy-pasteable npx commands + recovery flow. - CHANGELOG.md: D47 entry under Unreleased per release_kit overlay. AUTHORITY: - ADR 0007 — § 5 token format, § 9.1 minimal keygen command surface, § 9.3 recovery, § 10 acceptance criterion #9 covered. - CLAUDE.md release_kit overlay phase_rolling_mode — under Unreleased. - Standing autopilot grant. Verified: 544/544 pass via npm test (no regression in 524 pre-D47 tests; 20 new Suite 22 tests all green).

# OLP — Open LLM Proxy — Agent Guidelines
|
||
|
||
**Scope**: the `dtzp555-max/olp` repository.
|
||
**Audience**: any AI coding agent (Claude Code / Cursor / OpenCode / Copilot / Codex / Gemini) touching OLP source.
|
||
|
||
---
|
||
|
||
## What this project is
|
||
|
||
OLP (Open LLM Proxy) is a personal- and family-scale multi-provider LLM proxy. It exposes a single OpenAI-compatible HTTP endpoint (`/v1/chat/completions`) and routes each request to one of N provider plugins, each of which spawns the corresponding provider CLI (e.g. `claude -p`, `codex exec --json`, `vibe --prompt`). An IR (Intermediate Representation) normalizes between the entry surface and each provider's native shape. Intelligent fallback chains advance one provider at a time on configured triggers; content-addressed caching minimizes quota consumption.
|
||
|
||
OLP supersedes OCP (Open Claude Proxy) as of v1.0. The trigger was the 2026-05-14 Anthropic announcement (effective 2026-06-15) splitting CLI/Agent SDK traffic out of the Pro/Max subscription pool — OCP's foundational assumption ("subscription = unlimited within rate limits") broke for Anthropic on that date. Spreading risk across multiple providers is the structural response.
|
||
|
||
OLP is **not** a commercial multi-tenant SaaS, **not** an enterprise gateway competing with LiteLLM/OpenCode/CLIProxyAPI on breadth, **not** a model-capability router ("route to the smartest model"), and **not** a conversation-state store (clients manage their own state). See `ALIGNMENT.md` Core Principle and `docs/adr/0001-project-founding.md`.
|
||
|
||
Runtime: Node.js (ESM, `.mjs` throughout). No build step. No bundler. `server.mjs` is the single executable entrypoint. The architecture is spawn-binary: OLP spawns the real provider CLI for every uncached request.
|
||
|
||
---
|
||
|
||
## Stack
|
||
|
||
- Node.js >=18, native ESM modules
|
||
- `http`/`https` built-ins for the proxy core (no Express, no Fastify)
|
||
- `models-registry.json` as the single source of truth for `(provider, model) → metadata` mappings (analogous to OCP's `models.json`; SPOT discipline will be codified in a Phase 1 ADR — OLP ADR 0003 is currently the IR design, not the SPOT codification)
|
||
- GitHub Actions for CI (`alignment.yml`, `release.yml`, `test.yml`)
|
||
- `gh` CLI assumed for PR creation and release automation
|
||
- No TypeScript. No test framework beyond `test-features.mjs` (run via `npm test`; CI workflow `.github/workflows/test.yml`). Keep dependencies minimal.
|
||

|
||
|
||
## Key files to know
|
||
|
||
- `server.mjs` — HTTP listener, entry surface (`/v1/chat/completions`, `/health`, `/v1/models`, etc.), plugin loader, request dispatch. Governed by `ALIGNMENT.md`.
|
||
- `lib/providers/` — per-provider plugins. Each file (`anthropic.mjs`, `openai.mjs`, `mistral.mjs`, …) implements the Provider contract documented in ADR 0002.
|
||
- `lib/ir/` — Intermediate Representation definition + serializers. Governed by ADR 0003.
|
||
- `lib/cache/` — content-addressed cache layer (per-key isolation, `cache_control` bypass, chunked stream replay, singleflight). Governed by ADR 0005.
|
||
- `lib/fallback/` — fallback engine (trigger detection, chain advancement, idempotent-failure safety, header annotation). Governed by ADR 0004.
|
||
- `lib/keys.mjs` — multi-key auth, per-key namespacing, identity layer. Carries OCP's per-key isolation model into OLP. **✅ Phase 2 — D44 core + D45 server integration + D46 owner gating shipped (validateKey on every /v1/* + /health; chain filtered by providers_enabled; touchLastUsed fires post-response; /health payload trimmed for non-owner; X-OLP-Fallback-Detail gated by fallback_detail_header_policy).**
|
||
- `bin/olp-keys.mjs` — keygen CLI bootstrap surface per ADR 0007 § 9.1. **✅ Shipped at D47.** Subcommands: `keygen [--owner|--name=X|--providers=csv|--force]`, `list [--owner-only|--include-revoked]`, `revoke --id=X`. Plaintext token printed once on keygen. Installed via `package.json bin` so `npx olp-keys ...` works (also `npm run olp-keys ...`).
|
||
- `lib/audit.mjs` — append-only ndjson audit per ADR 0007 § 6.2 + § 8. **🟡 D45 — appendAuditEvent + getAuditDropCount shipped. Fires per /v1/chat/completions + /v1/models request including 401/403/5xx paths. Warn+1-retry on append failure; no memory buffer at Phase 2 (forward path).**
|
||
- `dashboard.html` — owner-only multi-provider dashboard (quota panels, fallback rate, cache hit rate). **📋 Planned (Phase 6) — not yet authored.**
|
||
- `models-registry.json` — single source of truth for `(provider, model) → metadata`. SPOT.
|
||
- `ALIGNMENT.md` — the constitution. Binding for any plugin / entry-surface / IR change.
|
||
- `docs/adr/` — Architecture Decision Records. Read the index in `docs/adr/README.md` before proposing governance, SPOT, or contract changes.
|
||
- `.github/workflows/alignment.yml` — CI blacklist grep + per-provider citation soft check; fails the build on known-hallucinated tokens.
|
||
- `CLAUDE.md` — Claude-Code-specific session instructions + `release_kit` overlay (Iron Rule 5.5).
|
||
|
||
**Implementation status note (as of 2026-05-25):** Files marked 📋 above are designed and documented but not yet on disk; files marked 🟡 are partially shipped; files marked ✅ are Phase 2 deliverables. The shipped set as of D47 is: `server.mjs` (with Phase 2 auth middleware + audit wire + owner-vs-non-owner gating), `lib/ir/`, `lib/providers/{anthropic,codex,mistral}.mjs`, `lib/cache/{keys,store}.mjs`, `lib/fallback/engine.mjs`, `lib/keys.mjs` (core + loadAuthConfigSync — D44 + D45), `lib/audit.mjs` (D45), `bin/olp-keys.mjs` (D47), `models-registry.json`, `test-features.mjs` (Suites 19–22). Phase 2 functional scope is complete; remaining is Phase 2 close → v0.2.0 (maintainer-triggered, explicit per CLAUDE.md `release_kit.phase_close_trigger`).

|
||
|
||
## Project-specific constraints
|
||
|
||
- **`ALIGNMENT.md` is binding.** Any PR touching a provider plugin, the entry surface, or the IR must cite the relevant authority (provider CLI documentation / OpenAI spec URL / ADR number) in the commit body and PR description. See `CLAUDE.md` § "Hard requirements for plugin / server.mjs changes" and `ALIGNMENT.md` Rules 1, 2, 5.
|
||
- **Alignment CI is not suppressible.** The `alignment.yml` workflow greps for known-hallucinated tokens (currently carrying OCP's `api.anthropic.com/api/oauth/usage` as a transitive guardrail) and runs per-provider sanity checks. Adding new blacklist tokens is done via PR amendment to `alignment.yml`; removing entries requires an `ALIGNMENT.md` amendment PR.
|
||
- **No self-approval.** Implementation author cannot merge their own PR (Iron Rule 10). A fresh-context reviewer must open the cited authority and confirm in the review comment.
|
||
- **`models-registry.json` is the only place to add/edit `(provider, model)` metadata.** Do not touch hardcoded model maps in `server.mjs`, `lib/providers/*.mjs`, or `setup.mjs` (📋 `setup.mjs` is planned, not yet authored). The OLP ADR that codifies this SPOT discipline lands in Phase 1 (OCP's ADR 0003 — `models.json` SPOT — is the precedent; OLP needs its own SPOT ADR because the registry shape differs).
|
||
- **Provider plugins follow the contract in ADR 0002.** A new provider plugin must implement every method on the Provider contract (`name`, `displayName`, `models`, `auth`, `spawn`, `estimateCost`, `quotaStatus`, `healthCheck`, `hints`). Partial implementations are unalignable per `ALIGNMENT.md` Rule 4.
|
||
- **No anti-fingerprinting.** OLP is honest about spawning the real CLI. If a provider detects subscription-spawn proxying and bans it, the response is to drop the provider per ADR 0006, not to mask the spawn.
|
||
- **No conversation state.** OLP is a stateless proxy. Memory / continuity is the client's responsibility (see ADR 0001 § Non-mission).
|
||

|
||
|
||
## Release protocol
|
||
|
||
OLP follows the machine-readable `release_kit:` overlay in `CLAUDE.md` (Iron Rule 5.5). Before any version bump or tag push, re-read that YAML block and walk every item in `new_feature_doc_expectations` and `bootstrap_quirk_policy`. Tag push triggers `.github/workflows/release.yml`, which creates the GitHub Release automatically — do not create the release manually.
|
||
|
||
Version is sourced from `package.json`; changelog from `CHANGELOG.md`; user-facing docs from `README.md`. The Supported Providers table in `README.md` is sourced from `models-registry.json` per the overlay; do not hand-edit it out of sync.
|
||
|
||
---
|
||
|
||
## Handoff expectations
|
||
|
||
A fresh session picking up OLP work should read, in order:
|
||
|
||
1. This file (`AGENTS.md`).
|
||
2. `ALIGNMENT.md` — constitution; non-optional.
|
||
3. `CLAUDE.md` — tool-specific instructions and `release_kit` overlay.
|
||
4. `docs/adr/` — most recent ADRs first; they explain why the current structure exists. Founding ADRs 0001–0006 are the OLP-bootstrap set.
|
||
5. `~/.cc-rules/memory/projects/olp_v0_1_spec.md` — the v0.1 spec (authoritative for OLP scope until v1.0 ships).
|
||
6. `~/.cc-rules/memory/auto/MEMORY.md` — cross-machine memory index.
|
||
|
||
Only after these should the session touch code.
