Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00056 | $0.02518 |
| Opus 5 | $0.00028 | $0.01259 |
| Sonnet 5 | $0.00011 | $0.00504 |
| Haiku 4.5 | $0.00006 | $0.00252 |
Grade A, and why
gitnexus-guide 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 2d 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.
This is a copy
100% identical to gitnexus-guide — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitNexus Guide
Quick reference for all GitNexus MCP tools, resources, and the knowledge graph schema.
Always Start Here
For any task involving code understanding, debugging, impact analysis, or refactoring:
- Read
gitnexus://repo/{name}/context— codebase overview + check index freshness - Match your task to a skill below and read that skill file
- Follow the skill's workflow and checklist
If step 1 warns the index is stale, run
node .gitnexus/run.cjs analyzein the terminal first.

Tools Reference
| Tool | What it gives you |
|---|---|
query |
Process-grouped code intelligence — execution flows related to a concept |
context |
360-degree symbol view — categorized refs, processes it participates in |
impact |
Symbol blast radius — what breaks at depth 1/2/3 with confidence |
trace |
Shortest path between two symbols — "how does A reach B?" in one call |
detect_changes |
Git-diff impact — what do your current changes affect |
rename |
Multi-file coordinated rename with confidence-tagged edits |
cypher |
Raw graph queries (read gitnexus://repo/{name}/schema first) |
explain |
Persisted taint findings — source→sink data flows (needs analyze --pdg) |
pdg_query |
Control/data dependence — what gates X (CDG) / where Y flows (REACHING_DEF); needs analyze --pdg |
check |
Check graph invariants such as circular imports |
route_map |
API route map — which components/hooks fetch which endpoints, and the handler files that serve them |
shape_check |
Response-shape drift — keys each route returns vs keys its consumers access (flags MISMATCH) |
api_impact |
Pre-change report for an API route — consumers, middleware, shape mismatches, risk level |
tool_map |
MCP/RPC tool definitions and the files that handle them |
group_list |
List configured multi-repo groups, or one group's config |
group_sync |
Rebuild a group's Contract Registry (cross-repo HTTP contract links); run after group.yaml changes or member re-index |
list_repos |
Discover indexed repos (paginated — limit/offset) |
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.

gitnexus-guide is a skill published in the GitHub repository youssefvdel/docsGround (1 stars, last pushed 15d ago), licensed MIT. It adds 56 tokens to every session and 2,518 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to gitnexus-guide, differing in 0 lines, and is treated as a copy.
