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 | $0.00514 | $0.00514 |
| Opus 5.5 | $0.00206 | $0.00206 |
| Sonnet 5.5 | $0.00103 | $0.00103 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
prism 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.
How it starts
The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Claude / Agent Notes for Prism
Companion to
AGENTS.md. Follow both.
Project
Prism — local context and change checks for coding agents, exposed via Core, MCP, CLI, and IDE extensions.
Before writing code
- Confirm Master Plan status is APPROVED (
plans/00_MASTER_DEVELOPMENT_PLAN.md). - Confirm M-000 Architecture Documentation is Verified (HLD/LLD/tech docs under
plans/architecture/). - Confirm exactly one milestone is
In Progressinplans/PROGRESS.md. - Work only on
milestone/M-XXX-…branch created from latestmain. - Implement only that milestone’s In Scope items.
First code milestone is M-001 (after M-000).
Do not
- Develop on
main - Stack milestone branches
- Create git commits before the owner explicitly approves (keep work in the working tree until then)
- Push remotes unless the human owner explicitly requests it
- Bypass
@repo-prism/corefrom MCP/CLI/extensions - Add cloud/network dependencies to Core analysis paths
- Expand milestone scope silently
Preferred workflow
Read milestone doc → implement (no commits) → bun run verify:milestone → fix → request owner review → owner approves → commit on milestone branch → owner approves merge → merge locally to main → mark Verified → share short “what changed” snippet with owner → next branch from main
Packages (mental model)
| Package | Role |
|---|---|
| shared | contracts |
| analyzer / indexer / graph-engine | engine internals |
| intelligence / impact / navigation | domain engines |
| checks | receipt checks |
| plugin | Claude Code plugin pack, skills and hooks |
| daemon | one local process that keeps each repo's index fresh and answers over loopback (ADR-0063) |
| core | public SDK (analysis) |
| mcp-server / cli | surfaces |
| ui | components for the docs website |
MCP
Tools call Core and return JSON-serializable DTOs from @repo-prism/shared.
Nine tools are registered by default; opt-in tools come from ~/.prism/config.json extraTools[].
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.

prism CLAUDE.md is an instructions file published in the GitHub repository Shailesh200/prism (10 stars, last pushed 6d ago), licensed MIT. It adds 514 tokens to every session, about $0.0021 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 2026-08-31.
