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-lint 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 4d 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.

Wiki Lint

Audit the wiki for quality and consistency issues.

Workflow

Step 1: Read the full index

Read memory/wiki/index.md to get the complete page catalog.

Step 2: Check each category

Contradictions

  • Scan pages that reference the same entities or concepts
  • Flag claims that conflict across pages
  • Note which sources support each side
  • Recommend resolution (usually: update the older claim with a note)

Stale claims

  • Check page frontmatter updated dates
  • Flag pages not updated in recent ingests that cover topics where new sources exist
  • Identify claims that newer sources have superseded

Orphan pages

  • Find pages with no inbound [[wikilinks]] from other pages
  • These may be valid standalone pages or may indicate missing cross-references

Missing pages

  • Scan for [[wikilinks]] that point to pages that don't exist yet
  • Identify important concepts mentioned frequently but lacking their own page

Missing cross-references

  • Find pages that discuss the same entities but don't link to each other
  • Suggest wikilinks that should be added

Knowledge gaps

  • Based on the topics covered, suggest:
    • Questions worth investigating
    • Sources worth finding
    • Angles not yet explored

Step 3: Report

Produce a structured report:

# Wiki Health Report — [date]

## Contradictions (X found)
- [page-a] vs [page-b]: [description of conflict]

## Stale Claims (X found)
- [page]: last updated [date], but [newer-source] may supersede

## Orphan Pages (X found)
- [page]: no inbound links

## Missing Pages (X found)
- [[concept-name]]: referenced in [N] pages but has no page

## Missing Cross-References (X found)
- [page-a] and [page-b] both discuss [topic] but don't link

## Suggested Investigations
- [question or source suggestion]

Step 4: Log

Append to memory/log.md:

## [YYYY-MM-DD] lint | Wiki Health Check
- Contradictions: X
- Stale claims: X
- Orphan pages: X
- Missing pages: X
- Missing cross-references: X

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.
