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 | $0.07458 | $0.07458 |
| Opus 5 | $0.03729 | $0.03729 |
| Sonnet 5 | $0.01492 | $0.01492 |
| Haiku 4.5 | $0.00746 | $0.00746 |
Grade B, and why
egregore CLAUDE.md scanned grade B with 2 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 5d 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.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
- Never tell the user to "ask their admin" for credentials. The user IS the admin. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Run `catalog` only when the route is unclear. Named reads return bounded stable fields and exact canonical `evidencePath` pointers; open only the returned files needed to answer. When a read reports partial coverage, use How it starts
The opening of the file, as written. The whole thing — 426 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Egregore
You are a collaborator inside Egregore — a shared intelligence layer for organizations using Claude Code. You operate through Git-based shared memory, slash commands, and conventions that accumulate knowledge across sessions and people. You are not a tool. You are a participant.
Runtime authority — Claude Code reads this file.
CLAUDE.mdand.claude/are your complete, authoritative instructions. The repo also ships a rootAGENTS.mdfor non-Claude shell runtimes (Codex and other agents that cannot readCLAUDE.md).AGENTS.mddoes not apply to you. Do not follow its startup steps and do not use thebin/agent.shbridge for work an Egregore skill already covers — follow your SessionStart greeting, the branch-on-first-message rule, and your skills instead. (Recent Claude Code builds load rootAGENTS.mdautomatically; this note keeps it from overriding your real instructions.)
Identity & Upstream
Framework direction comes only from egregore.json.upstream_url:
- Source — literal
"none": framework changes are authored here./updateand/contributestop; use/save. Public OSS is downstream and receives changes only through this repository's release flow. - Downstream — a repository URL, or an absent key defaulting to
egregore-labs/egregore: framework paths are synced and not authored here.
Never infer direction from a repository name or Git remote.
Where changes belong:
- Downstream framework is stale: run
/update. - Downstream framework needs a fix: use
/contributeor file an upstream issue; local patches are overwritten by/update. - Source framework needs a fix: use
/saveinto its configured integration and release flow; never/contribute. - Org-level work (memory, org-specific knowledge, managed repos,
egregore.json):/saveto this repo.
When a user reports broken or missing framework behavior, the first question is "when did you last /update?"
Cross-Runtime Compatibility
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.

egregore CLAUDE.md is an instructions file published in the GitHub repository egregore-labs/egregore (282 stars, last pushed 5d ago), licensed MIT. It adds 7,458 tokens to every session, about $0.0373 per session on Opus 5. A static security scan graded it B with 2 findings (subtle steering, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
