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 | $0.00152 | $0.01753 |
| Opus 5 | $0.00076 | $0.00877 |
| Sonnet 5 | $0.00030 | $0.00351 |
| Haiku 4.5 | $0.00015 | $0.00175 |
Grade A, and why
codebase-wiki 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.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Wiki pack — how to work here
This project holds an agent-authored wiki of a codebase — DeepWiki, but living in the repo. A coding agent reads the source and writes a navigable, diagram-rich, source-grounded wiki as markdown under wiki/. It is version-controlled and diffable, private by default, human+agent co-editable, renders in OK's live preview, and doubles as durable grounding context for future agent sessions. There is no separate Q&A surface — Q&A is "the OK-grounded agent + search".
This skill is pack guidance. The platform
/open-knowledgeskill (read/write/preview/linking/grounding rules) still governs every markdown operation — this layers the wiki workflow on top.
The shape
wiki/
OVERVIEW.md hub: what it is, a big-picture architecture diagram, a nav map to every section.
Frontmatter carries `profile` (audience/depth) + `source_commit` (freshness anchor).
log.md append-only generation / refresh audit trail
architecture/ system boundaries, layers, subsystems, cross-cutting concerns + diagrams
modules/ one page per package / module: purpose, entry points, key files, deps
flows/ key end-to-end flows as sequence / flow diagrams + narrative
concepts/ glossary: atomic pages for domain terms / core abstractions
guides/ task-oriented "how / where do I change X" (filled at depth >= standard)
Generating + refreshing
Don't free-hand it — read references/generate-and-refresh.md and follow the phased, STOP-gated procedure. It auto-detects mode: a stubbed OVERVIEW.md (empty source_commit) → generate (survey → overview → architecture → modules → flows → concepts → link-graph audit); a stamped source_commit → refresh (diff source_commit..HEAD, update only affected pages, re-stamp).
Two toolsets. Read source code with NATIVE tools (Read/Grep/Glob/Bash) — OK MCP does not index non-markdown source. Author and audit the wiki with OK MCP verbs (write/edit for pages, links/search for the graph). Never hand-write wiki markdown with native Write/Edit.
What ships with it
2 files 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.

codebase-wiki is a skill published in the GitHub repository inkeep/open-knowledge-skills (6 stars, last pushed 4d ago), licensed MIT. It adds 152 tokens to every session and 1,753 once invoked, about $0.0008 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.
