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

validate-links 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The Iron Law

LINKS MUST BE BIDIRECTIONAL. If A links to B, B must reference A.

When to Use

  • After creating new entity (called by world-bible)
  • After major vault reorganization
  • When checking vault health
  • When user asks about link integrity

The Process

Phase 1: Identify Scope

Determine what to validate:

  • Single file: Check all links in/out of one file
  • Folder: Check all files in a folder
  • Full vault: Check entire 02_World/ structure

Phase 2: Extract Links

For each file in scope:

Outgoing links:

  • All [[wikilinks]] in content
  • All links in frontmatter (related_characters, etc.)

Incoming links:

  • All files that link TO this file
  • Search vault for [[Filename]]

Phase 3: Check Link Resolution

For each outgoing link:

  • Does target file exist?
  • Is filename spelled correctly?
  • Is path correct?

Mark as:

  • ✓ Valid (resolves to file)
  • ✗ Broken (no target file)
  • ⚠ Possible typo (similar file exists)

Phase 4: Check Bidirectionality

For each relationship:

  • If A links to B, does B reference A?
  • Reference can be wikilink OR text mention in appropriate section

Mark as:

  • ✓ Bidirectional
  • ⚠ One-way (needs backlink)

Phase 5: Identify Orphans

Find files with:

  • No incoming links (nothing references them)
  • No outgoing links (reference nothing)

Orphan types:

  • Isolated: No links in either direction
  • Dead-end: Has incoming but no outgoing
  • Unreferenced: Has outgoing but no incoming

Phase 6: Report Findings

## Link Validation: [Scope]

### Broken Links
- [File]: [[Missing Target]] ✗

### Missing Backlinks
- [File A] links to [File B]
  But [File B] doesn't reference [File A]
  → Add to [section] in [File B]

### Orphaned Files
- [File]: No incoming links (unreferenced)

### Summary
- Files checked: X
- Valid links: Y
- Broken links: Z
- Missing backlinks: N
- Orphaned files: M

Phase 7: Fix Issues (with approval)

For each issue, offer:

  • Broken link: Delete link or create target file?
  • Missing backlink: Add backlink to [section]?
  • Orphan: Delete or find appropriate link?

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.
