The plugin's SessionStart hook injected using-agent-skills/SKILL.md as
additionalContext on every session. Claude Code already discovers and
routes skills from their descriptions, so the hook stacks a second
router on the native one — the pattern docs/getting-started.md warns
against ("That creates two routers for the same task"), measured at
~3.5k wasted cache-creation tokens per session in #569.
Delete hooks/hooks.json (the registration; the plugin now ships no
hooks) and keep hooks/session-start.sh as a standalone script for hosts
without native skill routing, matching the fix shape suggested in the
issue. Update the hook header, CONTRIBUTING.md, codex-setup.md, and
gemini-cli-setup.md to match.
Introduces .gemini/commands/ with TOML definitions for 7 slash commands
(build, spec, planning, review, test, ship, code-simplify), enabling
Gemini CLI to auto-discover them from the project root.
The planning command is named /planning rather than /plan to avoid
conflicting with a Gemini CLI internal command name.
Updates README.md project structure tree and adds a Slash Commands
section with a reference table to docs/gemini-cli-setup.md.
