What is drip CLAUDE.md?

A set of instructions for Drip, a Rust command-line tool that reads and processes files. It covers building, testing, formatting, linting, local runs, and performance benchmarks.

Use it to build debug or release versions, run the test suite or individual tests, check code quality, try Drip on a real file, and run benchmarks.

It puts the project's exact development commands and platform-specific considerations in one place, reducing guesswork when changing or checking the code.

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	$0.02300	$0.02300
Opus 5	$0.01150	$0.01150
Sonnet 5	$0.00460	$0.00460
Haiku 4.5	$0.00230	$0.00230

Security

Grade A, and why

drip 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 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Build, test, lint

cargo build                                  # debug
cargo build --release                        # release (use this for benches)
cargo test                                   # full suite (~431 tests)
cargo test diff_accuracy::                   # run a module
cargo test modified_file_returns_unified     # run a single test by name
cargo fmt --all -- --check                   # CI enforces
cargo clippy --all-targets --locked -- -D warnings   # CI enforces

rusqlite uses the bundled feature — no system SQLite needed. CI matrix runs on Ubuntu / macOS / Windows; OS-specific paths exist for FSEvents (macOS), inotify (Linux), and ReadDirectoryChangesW (Windows) in drip watch.

Trying a local build against a real read

cargo test concurrency::                     # 15-process SQLite contention

Numbers from these scripts feed BENCHMARKS.md — re-run when changing the diff path or session storage.

Repository conventions

Branch from develop, not main. PRs target develop. main is release-only (driven by release-please).
Conventional Commits are enforced by CI (commitlint runs on PRs). Subject ≤ 100 chars, imperative, no trailing period. Sloppy subjects break the auto-generated CHANGELOG.
Every behavioural change needs a test. Refactors that don't change behaviour and don't unlock a future change won't be merged.
New dependencies need a clear perf or correctness justification — the binary is intentionally < 5 MB.
CHANGELOG.md is generated by release-please; never edit by hand.

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.
