A persistent Markdown knowledge base that stores project and session information across conversations.

It helps ingest, add, search, read, list, delete, and check the health of project documentation pages.

It prevents useful context from being lost and provides tools to find outdated pages, broken links, and other knowledge-base problems.

wiki — Skill for Claude Code by RobinNorberg

Install

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.

Any agent

npx skills add RobinNorberg/oh-my-copilot --skill wiki

Clone the repo

git clone --depth 1 https://github.com/RobinNorberg/oh-my-copilot

Made for: Claude Code.

Or install oh-my-copilot, the plugin that ships this one along with the rest of its 51 skills, 21 commands, 20 agents, 11 hooks, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00019	$0.00684
Opus 5	$0.00010	$0.00342
Sonnet 5	$0.00004	$0.00137
Haiku 4.5	$0.00002	$0.00068

Security

Grade A, and why

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 5d 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.

Origin

This is a copy

92% identical to wiki — 10 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Wiki

Persistent, self-maintained markdown knowledge base for project and session knowledge. Inspired by Karpathy's LLM Wiki concept.

Operations

Ingest

Process knowledge into wiki pages. A single ingest can touch multiple pages.

wiki_ingest({ title: "Auth Architecture", content: "...", tags: ["auth", "architecture"], category: "architecture" })

Query

Search across all wiki pages by keywords and tags. Returns matching pages with snippets — YOU (the LLM) synthesize answers with citations from the results.

wiki_query({ query: "authentication", tags: ["auth"], category: "architecture" })

Lint

Run health checks on the wiki. Detects orphan pages, stale content, broken cross-references, oversized pages, and structural contradictions.

wiki_lint()

Quick Add

Add a single page quickly (simpler than ingest).

wiki_add({ title: "Page Title", content: "...", tags: ["tag1"], category: "decision" })

List / Read / Delete

wiki_list()           # Show all pages (reads index.md)
wiki_read({ page: "auth-architecture" })  # Read specific page
wiki_delete({ page: "outdated-page" })    # Delete a page

Log

View wiki operation history by reading .omg/wiki/log.md.

Storage

Pages: .omg/wiki/*.md (markdown with YAML frontmatter)
Index: .omg/wiki/index.md (auto-maintained catalog)
Log: .omg/wiki/log.md (append-only operation chronicle)

Cross-References

Use [[page-name]] wiki-link syntax to create cross-references between pages.

Auto-Capture

At session end, significant discoveries are automatically captured as session-log pages. Configure via wiki.autoCapture in .omc-config.json (default: enabled).

Hard Constraints

NO vector embeddings — query uses keyword + tag matching only
Wiki pages are git-ignored by default (.omg/wiki/ is project-local)

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.
