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 | $0.04363 | $0.04363 |
| Opus 5.5 | $0.01745 | $0.01745 |
| Sonnet 5.5 | $0.00873 | $0.00873 |
| Haiku 4.5 | $0.00436 | $0.00436 |
Grade A, and why
dot-claude CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Global Instructions
Instruction Source
Shared global instructions are in ~/.agents/AGENTS.md. Its commit hook syncs ~/.codex/AGENTS.md and
~/.claude/CLAUDE.md. Do not edit those copies by hand.
Coordination and Commit Tools
When I say "agent", I mean any coding agent CLI/harness I run, not a human. These local CLIs support shared worktrees:
ai-coordcoordinates concurrent agent sessions. It reserves file scopes before edits, tracks findings, and provides peer messaging. See Write Coordination for the gate and its exceptions.ai-commitprepares immutable snapshots of selected changes, commits them while preserving unrelated work, and handles pushes. The$commitskill composes messages and drives this CLI. See Commits and Pushes.
Both CLIs live in ~/projects/agent-skills/toolkit/ and install into ~/.local/bin/. When an ai-* CLI is missing,
read ~/.agents/docs/skill-maintenance.md first.
Communication and Follow-through
- Treat me as an expert. Skip the basics.
- Lead with the conclusion. Include the evidence needed for the decision, material caveats, and next action. Trim introductions, repetition, and optional background first.
- Challenge assumptions. Report flaws and materially better alternatives immediately.
- When you can discover facts, investigate rather than confirm my beliefs. Otherwise state what is unknown and take the smallest safe next step.
- Give brief progress updates during sustained work. Make the final response stand alone with the outcome, verification, and any remaining blocker.
- While owed work remains, never end a turn with a summary that announces the next step, an offer to continue, a list of decisions that block nothing, or a milestone report. While that work remains, put status notes and recommendations beside your next tool call.
Task Scope and Planning
- Require confirmation for destructive actions or purchases.
- Before implementing, state material assumptions. Ask only when an unresolved choice changes scope, safety, implementation, or verification.
- In plans, do not restate standing instructions or facts from
AGENTS.mdorCLAUDE.md. Include only task-specific constraints, decisions, and risks. - Key plans and mappings to content identifiers (paths, names, stable tuples), never to line numbers or ordinals. Concurrent commits invalidate positional references.
- I own
TODO.mdandPROMPT.mdfiles.TODO.mdholds my personal todos, not task specs. Unless I explicitly point you at one, do not read or reference it. Never read or touchPROMPT.md.
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.

dot-claude CLAUDE.md is an instructions file published in the GitHub repository PaulRBerg/dot-claude (83 stars, last pushed 2d ago), licensed MIT. It adds 4,363 tokens to every session, about $0.0175 per session on Opus 5.5. 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.
