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

obsidian-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 12d 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 — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Format, validate, and fix wiki links according to vault conventions.

When to Use This Skill

Activate when you need to:

  • Create wiki links to other vault files
  • Add section links to specific headers
  • Format links in YAML frontmatter properties
  • Verify links point to existing files/sections
  • Find and fix broken links
  • Validate link integrity in documents

1. Complete Filename Format

Always use full filename with date prefix:

✅ CORRECT: [[2025-10-31 Project Notes]]
❌ INCORRECT: [[Project Notes]] (missing date)
❌ INCORRECT: [[2025-10-31]] (missing title)

2. Folder Path Conventions

Include folder prefix for clarity:

✅ CORRECT: [[Journal/2025-10-31]]
✅ CORRECT: [[Articles/2025-10-31 Perennial Seller]]
✅ CORRECT: [[Roundup/2025-10-31]]

Rule: Use consistent folder prefixes for clarity and navigation.

3. Section Links

Use exact header text, character-for-character:

Source file header:
## PKM System Maintenance

✅ CORRECT:
[[Journal/2025-10-31#PKM System Maintenance]]

❌ INCORRECT:
[[Journal/2025-10-31#PKM System]] (truncated)
[[Journal/2025-10-31#pkm-system-maintenance]] (slug format)

Critical: Match characters, punctuation, spacing exactly as written.

4. Link to Sources, Not Indices

Always link to original content, not topic aggregations:

✅ CORRECT: [[Articles/2025-08-15 Skill Development]]
❌ INCORRECT: [[Topics/Career#Skill Development]]

Reason: Maintains source attribution and traceability

5. Properties Link Format

Wrap links in quotes when used in YAML lists:

sources:
  - "[[Journal/2025-10-31]]"
  - "[[Articles/2025-10-31 Title]]"

links:
  - "[[Roundup/2025-10-31]]"

attendees:
  - "[[People/John]]"

1. Search Before Link

ALWAYS verify target exists before creating link:

Process:
1. Search for target file using Glob or Grep
2. Verify file exists
3. If section link, read file and verify header exists
4. Create link with exact filename and header text

❌ NEVER:
- Guess at filenames
- Assume files exist
- Fabricate section headers

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.
