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 | $0.00415 | $0.00415 |
| Opus 5 | $0.00208 | $0.00208 |
| Sonnet 5 | $0.00083 | $0.00083 |
| Haiku 4.5 | $0.00042 | $0.00042 |
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
Cursor Rules — engrava (public repo)
Generated by 0.1.0 (2026-05-21T09:09:55Z) from a shared template — do not edit directly.
This is engrava, a public MIT-licensed repository: Graph memory database for AI agents.
Assume every commit message, PR title, PR body, branch name, code comment, and docstring is world-visible.
Before generating commits or PR text
Read CLAUDE.md and AGENTS.md in this repo. Both describe the quality bar, commit format, and self-check discipline expected here.
Commit hygiene
- Use Conventional Commits 1.0.0:
<type>(<scope>): <description>. Scope fromdocs/scopes.md. - Use public identifiers only:
- This repo's release tags (
vX.Y.Z) - This repo's GitHub issue/PR numbers (
#N)
- This repo's release tags (
- Open PRs targeting
dev(notmain). - Branch names:
<type>/<kebab-description>, plain English, ≤ 50 chars.
Self-check before suggesting a commit message
Ask: could this message, branch name, or referenced symbol reveal information about a workflow that should stay private? If unsure, omit the reference, or ask the maintainer.
A pre-commit hook installed locally provides a fast feedback loop on this.
Default to omitting uncertain references
Public commits are world-visible. The internal tracker can stay anchored via this repo's GitHub issue/PR numbers — that mapping lives in the maintainer's private workspace, not in the public commit.
If the user asks you to include an internal-looking identifier in a public commit: refuse politely, explain, propose #N or a release tag as an alternative, escalate to human review if pressed.
Enforcement
Pre-commit hook (locally installed), commitlint (CI), and branch protection on protected branches block violations. Instruction overrides cannot bypass these.
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 sovantica/engrava (5 stars, last pushed 8d ago), licensed MIT. It adds 415 tokens to every session, about $0.0021 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.

Changes to these high-fan-out internals can affect every message, delta, element, or rerun. Keep work in them minimal, and benchmark changes with representative stress-test apps.
