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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.00419 |
| Opus 5 | $0.00017 | $0.00210 |
| Sonnet 5 | $0.00007 | $0.00084 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
repo-architecture 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 10d 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.
This is a copy
100% identical to repo-architecture — 0 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.
What it actually says
Repo Architecture — Filing Rules
Full filing rules: See
skills/_brain-filing-rules.md
Contract
This skill guarantees:
- Every new page is filed by primary subject (not format, not source)
- The decision protocol is followed for ambiguous cases
- Common misfiling patterns are caught
Phases
- Identify the primary subject. What would you search for to find this page?
- Walk the decision tree:
- About a person →
people/{name-slug}.md - About a company →
companies/{name-slug}.md - A reusable concept/framework →
concepts/{slug}.md - An original idea →
originals/{slug}.md - A meeting →
meetings/{slug}.md - Media content →
media/{type}/{slug}.md - Raw data import →
sources/{slug}.md
- About a person →
- Cross-link. Link from related directories.
- Check notability. See
skills/conventions/quality.mdnotability gate.
Output Format
Advisory: "File this at {type}/{slug}.md because the primary subject is {reason}."
Anti-Patterns
- Filing by format ("it's a PDF so it goes in sources/")
- Filing by source ("it came from email so it goes in sources/")
- Creating pages without checking if one already exists
- Using
sources/for anything except raw data dumps
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.

repo-architecture is a skill published in the GitHub repository cynthiajones34/GBrain (0 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 419 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to repo-architecture, differing in 0 lines, and is treated as a copy.
