Claude Code internals - hooks, skill frontmatter, headless mode, and extension debugging, current as of June 2026. Triggers: hooks, hook events, hook not firing, PreToolUse/PostToolUse/SessionStart, skill frontmatter, SKILL.md, skill not triggering, headless, claude -p, CI/CD scripting, plugin validate, MCP server not connecting, agent vs skill vs command vs hook.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Code Internals One skill for the machinery of Claude Code itself: the **hook system**, the **skill format**, **headless/programmatic use**, and **debugging your configuration**. Replaces the former claude-code-hooks / claude-code-headless / claude-code-debug skills, refreshed against the June 2026 docs. > Written against Claude Code ~v2.1.17x. These surfaces move fast — when precision matters, confirm against the live docs (links per section). Two contracts from older guides are **dead**: the `$TOOL_INPUT` env-var hook contract (hooks read **stdin JSON** now) and standalone command files as a separate system (commands merged into skills). ## Route to the Right Reference | You're doing | Load | |---|---| | Writing/fixing a hook; event contracts; blocking tools; audit logging | [references/hooks-reference.md](references/hooks-reference.md) | | Authoring a skill; frontmatter fields; `$ARGUMENTS`; `` !`cmd` `` injection; triggering problems | [references/skills-reference.md](references/skills-reference.md) | | `claude -p`; CI scripts; output parsing; stream-json; structured output; background agents | [references/headless-reference.md](references/headless-reference.md) | …

How to install
mdr add 0xdarkmatter/claude-mods/claude-code-ops@sha256:07416af52229d486The line at the top of this page pins the label git:20261005.ccf2db6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
