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 | $0.01363 | $0.01363 |
| Opus 5 | $0.00681 | $0.00681 |
| Sonnet 5 | $0.00273 | $0.00273 |
| Haiku 4.5 | $0.00136 | $0.00136 |
Grade B, and why
akidevrule CLAUDE.md scanned grade B with 1 finding 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 2d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- `skills/` contains the shared Agent Skills corpus (the `SKILL.md` open standard) deployed unmodified to `~/.claude/skills/`, `~/.gemini/config/skills/`, `~/.agents/skills/` (Codex CLI), `~/.kiro/skills/` (Kiro CLI), an How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
akidevrule
This repository is the source of truth for Aki's reusable Claude Code rule and skill baseline.
Project role
akidevrule packages Markdown rules, Claude Code skills, global Claude guidance, and installer fragments so the same baseline can be installed into another user's local Claude environment.
Treat this repository as a standards distribution project, not as an application repository.
Source of truth
- Edit canonical rule and skill content in this Git repository first.

Read it when you need to understand the full layout or how the smart router works. It is not an agent instruction file — it does not override this CLAUDE.md.
File naming conventions
Files in payload/ follow this convention:
RULE-*.md— constraint rules: behavior, coding, content, stack requirements.METHOD-*.md— analytical frameworks loaded on demand for auditing or optimization tasks.
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.

akidevrule CLAUDE.md is an instructions file published in the GitHub repository lacvietanh/akidevrule (9 stars, last pushed 2d ago), licensed MIT. It adds 1,363 tokens to every session, about $0.0068 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
