Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00513 | $0.00513 |
| Opus 5 | $0.00257 | $0.00257 |
| Sonnet 5 | $0.00103 | $0.00103 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
cursorrules 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.
What it actually says
CLARE Framework Rules
This project uses the CLARE framework. Detailed rules are in .cursor/rules/.
Core Rule
After editing a file, run ./clare/verify-ci.sh before marking work complete. Run it only in a turn where you edited a file — not in plan-mode, research, or read-only turns. See .cursor/rules/clare-workflow.mdc for the full procedure.
Cross-Agent Sync Rule
When CLARE agent configuration changes, update all supported agent environments in the same change:
- Copilot:
.github/copilot-instructions.mdandinstall/.github/copilot-instructions.md - Claude:
CLAUDE.mdandinstall/root/CLAUDE.md - Codex:
AGENTS.mdandinstall/root/AGENTS.md - Cursor:
.cursorrulesandinstall/root/.cursorrules - Roo/Zoo Code:
.roo/rules/clare.mdandinstall/.roo/rules/clare.md
Before Any File Change
Check clare/autonomy.yml for the file path:
full-autonomy→ proceedsupervised→ generate + add "⚠ Human review required"humans-only→ STOP, notify user, do not generate code
Five Principles
- [C] Constrained: rules exist in tests/linters, not comments
- [L] Limited: autonomy.yml defines where AI can work alone
- [A] Assertive: tests enforce invariants, not implementations
- [R] Reality-Aligned: one source of truth per domain concept
- [E] Ephemeral: regenerate generated code, never patch it
CLARE₂ Commands
When the CLARE₂ pipeline container is running:
/project:clare2-capture start— begin session JSONL capture/project:distill— trigger on-demand distillation pass
Full Rules
See .cursor/rules/ for detailed MDC rule files.
See clare/principles.md for the principle reference card.
See CLAUDE.md for the complete workflow specification.
CLARE₂ Temper Routing
Use clare_temper_route(project, task_kind, capabilities) for an opaque route
ID and send X-CLARE-Route-ID to the policy proxy. Never select/load adapters,
provide adapter paths, call raw vLLM management endpoints, or access Docker.
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.

cursorrules is a cursor rule published in the GitHub repository jketreno/clare (5 stars, last pushed 1mo ago), licensed MIT. It adds 513 tokens to every session, about $0.0026 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 2026-08-31.
