# src/hooks/ — 46 Lifecycle Hooks
|
||
|
||
**Generated:** 2026-02-24
|
||
|
||
## OVERVIEW
|
||
|
||
46 hooks across 39 directories + 6 standalone files. Three-tier composition: Core(37) + Continuation(7) + Skill(2). All hooks follow `createXXXHook(deps) → HookFunction` factory pattern.
|
||
|
||
## HOOK TIERS
|
||
|
||
### Tier 1: Session Hooks (23) — `create-session-hooks.ts`

## KEY HOOKS (COMPLEX)
|
||
|
||
### anthropic-context-window-limit-recovery (31 files, ~2232 LOC)
|
||
Multi-strategy recovery when hitting context limits. Strategies: truncation, compaction, summarization.
|
||
|
||
### atlas (17 files, ~1976 LOC)
|
||
Master orchestrator for boulder sessions. Decision gates: session type → abort check → failure count → background tasks → agent match → plan completeness → cooldown (5s). Injects continuation prompts on session.idle.
|
||
|
||
### ralph-loop (14 files, ~1687 LOC)
|
||
Self-referential dev loop via `/ralph-loop` command. State persisted in `.sisyphus/ralph-loop.local.md`. Detects `<promise>DONE</promise>` in AI output. Max 100 iterations default.
|
||
|
||
### todo-continuation-enforcer (13 files, ~2061 LOC)
|
||
"Boulder" mechanism. Forces agent to continue when todos remain incomplete. 2s countdown toast → continuation injection. Exponential backoff: 30s base, ×2 per failure, max 5 consecutive failures then 5min pause.
|
||
|
||
### keyword-detector (~1665 LOC)
|
||
Detects modes from user input: ultrawork, search, analyze, prove-yourself. Injects mode-specific system prompts.
|
||
|
||
### rules-injector (19 files, ~1604 LOC)
|
||
Conditional rules injection from AGENTS.md, config, skill rules. Evaluates conditions to determine which rules apply.
|
||
|
||
## STANDALONE HOOKS (in src/hooks/ root)
|
||
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| context-window-monitor.ts | Track context window percentage |
|
||
| preemptive-compaction.ts | Trigger compaction before hard limit |
|
||
| tool-output-truncator.ts | Truncate tool output by token count |
|
||
| session-notification.ts + 4 helpers | OS notification on session completion |
|
||
| empty-task-response-detector.ts | Detect empty/failed task responses |
|
||
| session-todo-status.ts | Todo completion status tracking |
|
||
|
||
## HOW TO ADD A HOOK
|
||
|
||
1. Create `src/hooks/{name}/index.ts` with `createXXXHook(deps)` factory
|
||
2. Register in appropriate tier file (`src/plugin/hooks/create-{tier}-hooks.ts`)
|
||
3. Add hook name to `src/config/schema/hooks.ts` HookNameSchema
|
||
4. Hook receives `(event, ctx)` — return value depends on event type
