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 | $0.00807 | $0.00807 |
| Opus 5 | $0.00404 | $0.00404 |
| Sonnet 5 | $0.00161 | $0.00161 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
rpg-encoder 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 2d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
rpg-encoder
Rust workspace for building Repository Planning Graphs (RPGs) — semantic code understanding via MCP.
Build & Verify
cargo fmt --all # format
cargo clippy --workspace --all-targets -- -D warnings # lint
cargo test --workspace # test (640+ tests)
cargo build --release -p rpg-mcp # release binary
Before every commit: run fmt, clippy, and test. All three must pass. Do not skip or suppress warnings.
Git Workflow
Branch naming
fix/*— bug fixesfeat/*— new featuresdocs/*— documentation onlychore/*— tooling, deps, version bumps
Commits
Use conventional commits:
fix:bug fixfeat:new featurechore:tooling, version bump, depsdocs:documentationrefactor:code restructure (no behavior change)test:adding or fixing tests
Issue-first workflow
- Open a GitHub issue describing the problem or feature
- Create a branch from
main(fix/issue-descriptionorfeat/issue-description) - Make commits on the branch
- Open a PR referencing the issue (
Closes #NorRef #N) - Merge via squash merge (
gh pr merge --squash --delete-branch) - Pull main locally after merge
Release process
- Bump version in root
Cargo.toml([workspace.package] version) ANDnpm/package.json - Run
cargo fmt && cargo clippy --workspace --all-targets -- -D warnings && cargo test --workspace - Commit:
chore: bump version to X.Y.Z - Tag:
git tag vX.Y.Z - Push:
git push origin main && git push origin vX.Y.Z - The release workflow auto-builds binaries, creates a GitHub release, and publishes to npm

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.

rpg-encoder CLAUDE.md is an instructions file published in the GitHub repository userFRM/rpg-encoder (33 stars, last pushed 3mo ago), licensed MIT. It adds 807 tokens to every session, about $0.0040 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 2026-08-30.
