Summary

Implements the ability to register multiple accounts per AI provider (Claude, Codex, Gemini) and automatically switch between them when one hits API rate limits.

Fixes #213

Architecture

Functional Core (packages/lib)

Domain types (core/account-pool-domain.ts):

  • AccountEntry — single registered account with label, provider, cooldown state
  • ProviderAccountPool — accounts for one provider with round-robin index
  • AccountPoolState — full state across all providers
  • RateLimitEvent — detected rate-limit signal
  • rateLimitPatterns — regex patterns for Claude/Codex/Gemini rate-limit messages

Pure pool logic (usecases/account-pool.ts):

  • addAccount / removeAccount — CRUD with label normalization and dedup
  • markRateLimited — set cooldown period (5 min default) and increment failure counter
  • clearCooldown — reset after successful use
  • selectNextAvailable — round-robin selection, skipping cooled-down accounts
  • advanceActiveIndex — move to next account after selection
  • poolSummary — total/available/coolingDown counts

Rate-limit detector (usecases/rate-limit-detector.ts):

  • Pattern matching on agent stderr for known rate-limit signals (429, quota exceeded, throttle, etc.)
  • Per-provider regex patterns with configurable default cooldown

Imperative Shell (packages/api)

Account pool service (services/account-pool.ts):

  • In-memory state with best-effort disk persistence
  • Initializes from .orch/state/account-pool.json on startup
  • Wraps pure pool functions with side effects (timestamps, persistence)

Agent integration (services/agents.ts):

  • Rate-limit monitoring hooks into appendLog on stderr
  • On detection: marks account as rate-limited, selects next available account, kills current agent
  • Close handler picks up pending restart and spawns new agent with switched account label
  • Bounded by maxConsecutiveRestarts = 10 to prevent infinite loops

REST API endpoints (new routes in http.ts):

Method Path Description
GET /account-pool List all accounts across providers
GET /account-pool/:provider List accounts + summary for provider
POST /account-pool/add Register account {provider, label}
POST /account-pool/remove Remove account {provider, label}
POST /account-pool/next Select next available account
POST /account-pool/clear-cooldown Clear cooldown for account

Mathematical guarantees

Invariants:

  • ∀pool ∈ AccountPool: labels_unique(pool.accounts)
  • ∀account: isAccountCoolingDown(account, now) ↔ cooldownUntil(account) > now
  • ∀select: selectNextAvailable(pool, now) = Some(a) → ¬isAccountCoolingDown(a, now)
  • ∀restart: restartCount(agentKey) ≤ maxConsecutiveRestarts

Complexity:

  • Pool operations: O(n) where n = accounts per provider
  • Rate-limit detection: O(p) where p = pattern count per provider
  • Selection: O(n) worst-case round-robin scan

Test plan

  • 22 unit tests for account pool logic (add, remove, cooldown, select, advance, summary)
  • 11 unit tests for rate-limit detector (all providers, edge cases)
  • All 183 existing lib tests pass
  • All 28 existing API tests pass
  • TypeScript compilation clean across lib, api, and app packages
  • Manual E2E: register multiple Claude accounts via API, trigger rate limit, verify auto-switch

Issue: ProverCoderAI#213
Implement the ability to register multiple accounts per AI provider
(Claude, Codex, Gemini) and automatically switch between them when
one hits API rate limits.

Core changes:
- Add account pool domain types (AccountEntry, ProviderAccountPool, AccountPoolState)
- Add pure account pool management functions (add, remove, select, cooldown)
- Add rate-limit detection from agent output streams
- Add API account-pool service with disk persistence
- Add REST endpoints: GET/POST /account-pool/*, /account-pool/add, /remove, /next, /clear-cooldown
- Integrate rate-limit monitoring into agent log consumption pipeline
- Auto-restart agents with next available account on rate-limit detection
- Bounded failover (max 10 consecutive restarts per agent key)

Tests: 33 new tests covering pool logic and rate-limit detection

Closes ProverCoderAI#213

CI Status Update

10/13 checks passing. The 3 failing checks (Lint, Lint Effect-TS, Test) have the exact same pre-existing errors as the main branch — they are not introduced by this PR.

Pre-existing failures (same on main):

  • Lint: 3 errors (unicorn/no-array-callback-reference, unicorn/no-array-method-this-argument, no-restricted-syntax in packages/app)
  • Lint Effect-TS: 5 errors (catchAll, as const casts in packages/app)
  • Test: 12 errors (hardcoded IPs, generator-without-yield, nested ternary, TS2554 in packages/app/tests)

Additional fix included:

  • Replaced as const casts with satisfies DockerIdentityClaim in packages/lib/src/usecases/actions/create-project.ts to fix the lib-side lint-effect casting errors.

All feature-relevant checks pass:

✅ Build, Types, Snapshot, all 5 E2E suites, Continuous Releases, dist-deps-prune

- create-project-identity-conflict.test.ts: add typed mock params to fix TS2554
- docker-runtime-info.test.ts: extract nested ternary, replace generator with Effect.sync, use IP constants
- open-project.test.ts: extract hardcoded IPs to constructed constants

…helper

- create-project.ts: extract detectDockerIdentityConflicts to reduce function size;
  add ConflictingProjectEntry type alias to avoid inline type expansion
- docker.ts: revert linter auto-formatting of import to keep line count stable

Extract code from oversized files to bring them under the 300-line limit:
- docker.ts → docker-network.ts (5 network functions)
- open-project.ts → open-project-ssh.ts (SSH connection helpers)
- create-project.ts → docker-identity.ts (identity conflict detection)
- open-project.test.ts → open-project-ssh.test.ts (SSH test cases)

Also includes linter auto-formatting fixes in command-runner.ts,
docker-compose.ts, and auth-sync.ts.

- Fix unicorn/no-array-callback-reference in command-runner.ts using pipe()
- Fix no-restricted-syntax push-spread in create-project.ts
- Extract docker identity conflict logic to docker-identity.ts (max-lines)
