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 | $0.06808 | $0.06808 |
| Opus 5.5 | $0.02723 | $0.02723 |
| Sonnet 5.5 | $0.01362 | $0.01362 |
| Haiku 4.5 | $0.00681 | $0.00681 |
Grade A, and why
PhilLit 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 11d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PhilLit is a multi-agent system to (a) author academic literature reviews for philosophy research, and (b) improve these agents. It is packaged as a distributable Claude Code plugin.
This
CLAUDE.mdis for plugin developers working in this repository. It does not load when PhilLit runs as an installed plugin from a user's own directory — runtime guidance lives in the skills (skills/*/SKILL.md) and agents (agents/*.md).
Mode
Production mode (default): When the user asks for a literature review, invoke the /phillit:literature-review skill to begin the 6-phase workflow. Skills and agents register only when the plugin is loaded — a bare dev clone registers none of them. To run a review against your checkout, launch claude --plugin-dir /path/to/PhilLit from a scratch directory (see CONTRIBUTING.md, Getting Started).
Development mode: Only if user explicitly asks to develop, improve, or test agents/skills. Work on definitions in agents/ and skills/.
Objectives
Main objective, above every other concern: build the best tooling to advance the norms in philosophy around using AI, and to show the AI-curious what AI can do for philosophy research. PhilLit and phillit-service are not a public professional product: practically nobody uses the service, and any users will be friends and acquaintances experimenting together.
Priority order for literature reviews (and agent development):
- Accurate — Only cite verified papers; never fabricate references
- Comprehensive — Cover all major positions and key debates
- Rigorous and concise — Analytical depth, tight prose; balanced presentation of positions
- Reproducible — Structured workflow, standard BibTeX output, Chicago author-date citations
NOT priorities:
- ❌ Speed — Quality over fast completion
- ❌ Context efficiency — Use full context as needed; don't optimize for token savings
- ❌ Professional-grade legal caution — exacting legal standards fit a real professional product, not this project (see the main objective). On copyright and licensing be very scrappy: never block, narrow or gate a feature for legal exposure only a public professional product would carry. For example, one user's uploaded PDF serves other users' reviews.
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.
