Agent Stack Hooks — Gap Analysis & Specs guide
Claude Code defines 30 hook events. The atlas graph and hooks-adapter canonical contract cover all 30, and adapters now registers native Claude runtime hooks for the concrete events that have a runtime source. This directory documents remaining SDK/platform emission gaps and specs for full parity.

30 Claude Code hook events vs. implementation status across the agent stack.
wiki/docs/agent-stack/hooks/coverage-matrix.md
Beyond the 13 missing events, the agent stack lacks several hook capabilities that Claude Code supports.
wiki/docs/agent-stack/hooks/missing-capabilities.md
These events are defined in the atlas graph and the hooks-adapter canonical contract. As of issue 636, hooks-adapter core, Claude adapter normalization/rendering, CLI invoke coverage, adapters Claude runtime hook registration, and SDK task lifecycle hooks cover the concrete surfaces that exist today.
