symphony CLAUDE.md

symphony CLAUDE.md is an instructions file for coding agents from broomva/symphony. It costs 2,865 tokens per session, scanned A, original, Apache-2.0.

A project guide for Symphony, a Rust service that coordinates coding agents and their work on tracked issues. It tells an agent which project documents to read and which commands to run.

In plain words
What is it for?
Use it to orient an agent, find the right documentation, understand Symphony’s crates, and run its smoke tests and command-line checks.
Why use it?
It reduces guesswork about the repository’s architecture, current plans, rules, and quality checks before making changes.

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.

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.

Security

Grade A, and why

symphony 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 3d 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.

CLAUDE.md - Symphony

Project

Symphony is a Rust-based orchestration service for coding agents. See AGENTS.md for architecture, PLANS.md for roadmap, CONTROL.md for quality gates.

Gathering Context

Before starting work, orient yourself using the knowledge graph:

  1. Read this file and AGENTS.md — conventions, architecture, obligations
  2. Check project statedocs/roadmap/Project Status.md and .planning/STATE.md
  3. Explore relevant docs — traverse [[wikilinks]] from the entry points:
    • docs/Symphony Index.md — vault navigation hub
    • docs/architecture/Crate Map.md — which crate owns what
    • docs/crates/<crate-name>.md — per-crate API, tests, spec coverage
    • docs/operations/Configuration Reference.md — WORKFLOW.md format
    • docs/operations/Control Harness.md — build gates, test counts
  4. Check CONTROL.md — setpoints your changes must satisfy
  5. Check PLANS.md — current phase and remaining tasks
  6. Check .planning/REQUIREMENTS.md — spec conformance checklist

When in doubt about behavior, consult the canonical spec: /Users/broomva/Downloads/Symphony SPEC.md.

Commands

  • make smoke — compile + clippy + test (the gate, runs pre-commit)
  • make check — cargo check + clippy
  • make test — cargo test --workspace (includes CLI integration tests)
  • make build — cargo build --release
  • make control-audit — smoke + format check (before PR)
  • make fmt — auto-format code
  • make install — install binary locally

CLI Testing

Integration tests in tests/cli_integration.rs verify the binary end-to-end:

  • symphony init scaffolds WORKFLOW.md correctly for both tracker types
  • symphony validate catches missing keys, invalid config
  • symphony config displays resolved settings (including pr_feedback, done_state)
  • Init → Validate round-trip: generated workflows pass validation
  • Remote daemon access: auth rejection works properly
  • Error paths: missing files, unsupported trackers, overwrite protection

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.
