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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.00719 |
| Opus 5 | $0.00026 | $0.00360 |
| Sonnet 5 | $0.00010 | $0.00144 |
| Haiku 4.5 | $0.00005 | $0.00072 |
Grade A, and why
anvien-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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Anvien Guide
Quick reference for all Anvien MCP tools, resources, and the knowledge graph schema.
Always Start Here
For any task involving code understanding, debugging, impact analysis, or refactoring:
- Read
anvien://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
anvien analyzein the terminal first.
Skills
| Task | Skill to read |
|---|---|
| Understand architecture / "How does X work?" | anvien-exploring |
| Blast radius / "What breaks if I change X?" | anvien-impact-analysis |
| Trace bugs / "Why is X failing?" | anvien-debugging |
| Rename / extract / split / refactor | anvien-refactoring |

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 |
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 anvien://repo/{name}/schema first) |
list_repos |
Discover indexed repos |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 11d ago First seen · 65 lines · 52 tokens per session scan A 81df8297f702
anvien-guide is a skill published in the GitHub repository tamnguyendinh/Anvien (9 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 719 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
blast-radius-review
Review a change by its blast radius, using Kin's graph to find what downstream code the change can reach. Use when reviewing a diff or pull request, deciding whether an edit is safe, or answering "what else breaks if I change this" in a repository admitted to Kin.
kin-retrieval
Read a codebase through Kin's semantic graph instead of grep and whole-file reads. Use when finding where something lives, what a symbol does, who calls it, or which code implements a described behavior, and when a repo has been admitted to Kin (a .kin/ directory exists).
booboo-deploy
Stand up a Booboo brain end to end — scaffold the project, write booboo.config.yaml against a real Postgres/Supabase or JSON source, build the snapshot, then wire the REST API, the MCP server, the 3D viewer and the panel. Use when someone wants a brain built for the first time, wants to point Booboo at their own…
booboo-troubleshoot
Diagnose a Booboo brain that is not working — an empty or tiny graph, a flat starburst view, missing MCP tools, a client that cannot find the snapshot, climbing orphan counts, or a build that exits clean but produces nothing. Use when a booboo build, serve, mcp, view, panel or vault command misbehaves.
booboo
Build, query, deploy and debug a Booboo brain — one graph fusing structure, knowledge, memory, agents and automations, queryable by REST or MCP and viewable in 3D. Use when the user mentions Booboo, booboo.config.yaml, brain.json, org.booboo.json, an organigram of agents, "boot my agent from the org", a 3D system…
booboo-adapter
Feed data into a Booboo brain that the built-in postgres and json adapters do not cover — write a small config-driven adapter against the spec instead of forking the builder. Use when a source is Neo4j, an API, a CSV export, a proprietary store, or any shape the standard config cannot express.
