FrontAgent: Skill for Claude Code

.agents/skills/gitnexus/gitnexus-cli/SKILL.md

gitnexus-cli is a skill for Claude Code from ceilf6/FrontAgent. It costs 59 tokens per session (842 once invoked), scanned A, a copy of gitnexus-cli, MIT.

A command-line tool for indexing a software repository and mapping its files, symbols, and relationships. A repository is the project folder containing the code and its version history.

In plain words
What is it for?
Use it to analyze or re-index a repository, check index status, clean the index, generate a project wiki, or list indexed repositories.
Why use it?
It gives a coding agent an up-to-date map of an unfamiliar codebase instead of making it inspect every file from scratch. It also shows whether the index is current.

Skill for Claude Code

Written for Claude Code: PostToolUse hook event. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md; mentions Codex.

This is ceilf6/FrontAgent's own configuration. It tells Claude Code how to work on FrontAgent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything FrontAgent configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gitnexus-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GitNexus CLI Commands

All commands work via npx — no global install required.

Commands

analyze — Build or refresh the index

npx gitnexus analyze

Run from the project root. This parses all source files, builds the knowledge graph, writes it to .gitnexus/, and generates AGENTS.md / AGENTS.md context files.

Flag Effect
--force Force full re-index even if up to date
--embeddings Enable embedding generation for semantic search (off by default)
--drop-embeddings Drop existing embeddings on rebuild. By default, an analyze without --embeddings preserves them.

When to run: First time in a project, after major code changes, or when gitnexus://repo/{name}/context reports the index is stale. In Codex, a PostToolUse hook detects staleness after git commit and git merge and notifies the agent to run analyze — the hook does not run analyze itself, to avoid blocking the agent for up to 120s and risking KuzuDB corruption on timeout.

status — Check index freshness

npx gitnexus status

Shows whether the current repo has a GitNexus index, when it was last updated, and symbol/relationship counts. Use this to check if re-indexing is needed.

clean — Delete the index

npx gitnexus clean

Deletes the .gitnexus/ directory and unregisters the repo from the global registry. Use before re-indexing if the index is corrupt or after removing GitNexus from a project.

Flag Effect
--force Skip confirmation prompt
--all Clean all indexed repos, not just the current one

wiki — Generate documentation from the graph

npx gitnexus wiki

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
