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 | $0.01300 | $0.01300 |
| Opus 5 | $0.00650 | $0.00650 |
| Sonnet 5 | $0.00260 | $0.00260 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
domain-experts 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 9d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Domain Experts — session bootstrap
Before doing ANY work in this repo, read these three files in full, in this order:
AGENTS.md— what lives where, the rules, release checklist, known pitfallsCONTRIBUTING.md— especially the "Exact recipe for adding a role (follow verbatim)" sectiondocs/CONTEXT.md— where the last session left off
Non-negotiables when adding or editing roles
- New roles are
spec: 2perAUTHORING.md: SKILL.md +references/trio, worked example with real reconciling numbers, each idea stated exactly once. - Order of operations: write files →
git add roles/<slug>→python3 scripts/lint_roles.py <slug>until 0 errors →python3 scripts/generate_roadmap.py→ commit everything together →git pull --rebase --autostash→ push. - Never hand-edit generated content: README role-count block, ROADMAP checklist,
data/roles.json. - Another session may be pushing to
mainconcurrently — always pull --rebase --autostash before push. - Quality bar: a practitioner should nod, not shrug. If a role would ship generic, skip it and pick another — an empty slot is recoverable, a generic role poisons trust.
Dual-Graph Context Policy
This project uses a local dual-graph MCP server for efficient context retrieval.
MANDATORY: Always follow this order
-
Call
graph_continuefirst — before any file exploration, grep, or code reading. -
If
graph_continuereturnsneeds_project=true: callgraph_scanwith the current project directory (pwd). Do NOT ask the user. -
If
graph_continuereturnsskip=true: project has fewer than 5 files. Do NOT do broad or recursive exploration. Read only specific files if their names are mentioned, or ask the user what to work on. -
Read
recommended_filesusinggraph_read— one call per file.graph_readaccepts a singlefileparameter (string). Call it separately for each recommended file. Do NOT pass an array or batch multiple files into one call.recommended_filesmay containfile::symbolentries (e.g.src/auth.ts::handleLogin). Pass them verbatim tograph_read(file: "src/auth.ts::handleLogin")— it reads only that symbol's lines, not the full file.- Example: if
recommended_filesis["src/auth.ts::handleLogin", "src/db.ts"], callgraph_read(file: "src/auth.ts::handleLogin")andgraph_read(file: "src/db.ts")as two separate calls (they can be parallel).
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.

domain-experts CLAUDE.md is an instructions file published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed yesterday), licensed MIT. It adds 1,300 tokens to every session, about $0.0065 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
