What is rpg-encoder CLAUDE.md?

Project instructions for a Rust workspace that builds Repository Planning Graphs, which represent relationships in source code to support code understanding through MCP. They define build, test, branch, and commit practices.

Formatting and checking Rust code, running the workspace tests, building the release MCP binary, naming branches, and preparing linked pull requests.

They set the checks and issue-based workflow required before changes are merged, helping catch formatting, warning, and test failures.

Token cost

What it costs to keep this loaded

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	$0.00807	$0.00807
Opus 5.5	$0.00323	$0.00323
Sonnet 5.5	$0.00161	$0.00161
Haiku 4.5	$0.00081	$0.00081

Security

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 2mo 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 fixes
feat/* — new features
docs/* — documentation only
chore/* — tooling, deps, version bumps

Commits

Use conventional commits:

fix: bug fix
feat: new feature
chore: tooling, version bump, deps
docs: documentation
refactor: 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-description or feat/issue-description)
Make commits on the branch
Open a PR referencing the issue (Closes #N or Ref #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) AND npm/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.
