What is smart-tree AGENTS.md?

A repository guide for Smart Tree, a Rust project that scans files and provides command-line, web, and other tools.

Use it when exploring the repository, building or testing Rust code, locating modules, checking formatting and linting, or preparing changes for review.

It gives contributors the project layout, build and test commands, coding conventions, and testing expectations in one place. This reduces guesswork when changing the codebase.

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	$0.00783	$0.00783
Opus 5.5	$0.00313	$0.00313
Sonnet 5.5	$0.00157	$0.00157

Security

Grade A, and why

smart-tree AGENTS.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.

Repository Guidelines

This guide gives contributors the essentials for working on Smart Tree in this repository. Keep updates concise and run the pre-commit checks before opening a PR.

Project Structure & Module Organization

src/: Main Rust crate. Key areas: main.rs/cli.rs (entry & clap args), scanner.rs (walks the filesystem), formatters/ (output formats), mcp/ (JSON-RPC tools), mem8/ (persistence), web_dashboard/ (web UI backend), and bin/ targets for st, mq, m8, n8x.
scripts/: Automation (manage.sh, build-and-install.sh) plus helper shell functions.
tests/: Rust integration tests; fixtures live alongside in test, test_files, and test-dirs.
docs/ and examples/: User-facing guides and sample outputs.
marqant/: Compression submodule; expert_prompt_engineer/: secondary workspace crate.

Build, Test, and Development Commands

./scripts/manage.sh test — pre-commit bundle: cargo test + cargo clippy -D warnings + cargo fmt --check.
cargo build --release — optimized binaries with TUI built-in; use --features full for local LLM (candle).
cargo run --bin st -- --help — smoke-test the CLI; add flags like --mode ai --compress as needed.
cargo test or cargo test name -- --exact --nocapture — run all or targeted tests with output.
cargo fmt --all -- --check and cargo clippy -- -D warnings — enforce style/lints when iterating.
./scripts/build-and-install.sh — rebuild and install locally, clearing shell command cache.

Coding Style & Naming Conventions

Rust 2021, 4-space indent. Keep functions small; prefer composition over long match blocks.
Use anyhow::Result with .context(...); avoid panics in library code.
File/module names snake_case; types/enums struct PascalCase; CLI flags stay kebab-case to match cli.rs.
Logging via tracing macros; keep comments brief and in the existing light, direct tone.

Testing Guidelines

Primary suite: cargo test; async tests use #[tokio::test].
Integration coverage in tests/; data fixtures under test/test_files/test-dirs.
CLI/regression scripts (test_spicy.sh, test_feature_flags.sh, etc.) can be run directly with bash.
For verbose diagnostics: RUST_LOG=debug cargo test -- --nocapture.
Aim for zero clippy warnings and add tests for new branches or error paths.

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.
