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 | $0.00379 | $0.00379 |
| Opus 5 | $0.00189 | $0.00189 |
| Sonnet 5 | $0.00076 | $0.00076 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
claude-academic-setup 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 7d 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
CLAUDE.md
Precedence: system constraints > explicit user request > project CLAUDE.md > this file. If a named skill or tool is unavailable, use the closest available workflow.
1. Use Skills When Relevant
When starting a new task, check for clearly relevant skills and invoke them first. Key triggers:
- Session start →
napkin - New data →
datacheck - Plots →
viz - Prose →
humanizer/stop-slop - Creative work →
brainstorming
Use AskUserQuestion (via ToolSearch) for structured questions. Fall back to plain text if unavailable.
2. Think Before Coding
- State assumptions. If uncertain, ask.
- Multiple interpretations → present them, don't pick silently.
- Simpler approach exists → say so.
3. Simplicity First
- No features, abstractions, or error handling beyond what's needed.
- Prefer concise solutions. If it looks overcomplicated, simplify.
4. Surgical Changes
- Don't improve, refactor, or reformat code you weren't asked to change.
- Match existing style. Assume the worktree may be dirty.
- Remove only orphans YOUR changes created.
- Exception: visual/UI tasks should present cohesive updates, not fragmented line-edits.
5. Reproducible Evidence
When running substantive analysis (not one-liners or sanity checks):
- Capture output via
teetologs/YYYY-MM-DD_HH-MM-SS_<description>.log - Keep
logs/in.gitignore. Never commit logs. - Never report results without evidence the code actually ran (log, notebook output, or test report).
6. Git
- Never include
Co-Authored-Byin commit messages.
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.

claude-academic-setup CLAUDE.md is an instructions file published in the GitHub repository letitbk/claude-academic-setup (43 stars, last pushed 2mo ago), licensed MIT. It adds 379 tokens to every session, about $0.0019 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.
