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 | $0.00388 | $0.00388 |
| Opus 5 | $0.00194 | $0.00194 |
| Sonnet 5 | $0.00078 | $0.00078 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
ai-dev-toolkit CLAUDE.md 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 6d 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.
What it actually says
ai-dev-toolkit (adt)
A CLI package manager for AI skills, agents, rules, and hooks across Cursor, Claude Code, and Codex.
What it does
adt is a zero-dependency Node.js CLI (bin/adt.js) that lets users install skill sources (git repos) and symlink them into harness directories — globally (~/.claude/, ~/.cursor/) or per-project (.claude/, .cursor/).
Key concepts
- Source — a git repo containing skills/agents/rules/hooks (e.g.
obra,karpathy) - Install — clones a source to
~/.adt/sources/; nothing is wired yet - Use — creates symlinks from the source into harness dirs; scope-aware (global vs project)
- Scope — project if inside a
.gitrepo or a dir with.adt; global otherwise
File layout
bin/adt.js — entire CLI (~1400 lines, single file, no deps)
catalog.json — built-in catalog of known sources
Commands
adt init — detect harnesses, write ~/.adt/ structure
adt install <source> — clone source to ~/.adt/sources/
adt use [--global] [src] — symlink source into harness dirs
adt uninstall — remove symlinks and cleanup
adt list — show installed sources
adt search — search the catalog
Conventions
- No external runtime dependencies — stdlib only
- All state in
~/.adt/(manifest, state, remote catalog cache) - Harness paths are defined in
globalHarnessDirs()andprojectHarnessDirs()at the top ofbin/adt.js - Catalog TTL: 24 hours for remote refresh
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.
