Adds PostToolUse hook that detects stale GitNexus index after git mutations (commit, merge, rebase, cherry-pick, pull) and notifies the agent to reindex. Uses lightweight staleness check (git rev-parse HEAD vs meta.json) instead of running gitnexus analyze synchronously, avoiding KuzuDB corruption and 120s blocks. Security and cross-platform hardening: remove shell:true from all spawnSync calls, use .cmd extensions on Windows, add path.isAbsolute(cwd) guards, fix setup.ts path escaping with JSON.stringify, use sendHookResponse() consistently. Includes 73 regression tests.
Skill descriptions were too tool-centric ("using knowledge graph", "blast
radius") which prevented Claude Code from matching them to user intent.
Rewritten to user-intent-driven format with "Use when..." phrasing and
example trigger phrases so Claude can semantically match user requests.
Updated across all 3 sources: gitnexus/skills/, gitnexus-claude-plugin/skills/,
.claude/skills/, and the ai-context.ts fallback generator.

Skill folder names determine invocation paths in Claude Code plugins
(e.g. plugin:gitnexus:gitnexus-cli). Generic names like "cli" or
"debugging" could collide with other plugins, so prefix them all with
gitnexus- for clarity.
Updated across plugin dirs, main package source files, ai-context.ts
generator, setup.ts installer, and all CLAUDE.md/AGENTS.md routing tables.
