A tool for turning a conversation, research session, or working document into a structured wiki page. A wiki is an organised collection of reusable pages that preserve knowledge.

In plain words
What is it for?
Use it to record what a discussion established, capture research findings, or update an existing wiki page with the current state of knowledge.
Why use it?
It prevents useful conclusions from being lost in temporary chats or scattered notes.

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

wiki-crystallize 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.

The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Wiki Crystallize

Distils ephemeral conversation into durable, structured wiki knowledge.


Config Discovery

Every invocation starts here. Wiki root is the directory containing wiki-config.md. Skills derive it at runtime. Pages this skill writes follow the structure in wiki-schema.md - both files need to be present.

  1. Identify scope: Determine your filesystem scope root - the top-level directory your filesystem tool can access.

  2. Scope check - MANDATORY STOP: If scope is bare drive root (C:\, D:\, /), OS root, or user home (C:\Users\X, /home/X, /Users/X) → stop immediately. Do not search. Do not attempt to locate wiki-config.md. Go directly to step 6.

  3. Scan <available_skills> for wiki-config. Note whether it's available - this shapes the recommendations below. The bundled references/setup-help.md is also available; read it if the user needs orientation or if you get stuck.

  4. Locate and read wiki-config.md: Search recursively (first-match, max 5 levels). If found, read it (blacklist, index_excludes, ingested_folder, ingested_subdirs, log_format). If not found, skip to step 6.

  5. Locate and read wiki-schema.md - mandatory check: In the same directory as wiki-config.md, verify wiki-schema.md exists and parses as YAML. Do not proceed to the Workflow below until you have a definite verdict (present / missing / malformed). Then:

    • Present and parses cleanly → read the schema (mandatory_fields, conditional_fields, enums) and proceed to the Workflow.

    • Missing → STOP. Do not proceed. Do not deploy. Response depends on whether wiki-config is in <available_skills> (from step 3):

      • wiki-config available: Output exactly this pattern - "Your wiki is missing wiki-schema.md. Run /wiki-config to deploy it and complete setup. I'll wait for that to be done before proceeding." End of turn. Do not offer bundled deployment; do not present alternatives. wiki-config's guided flow is the correct path when wiki-config is available.

What ships with it

3 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.

Changes

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.
