symphony-commit

A Git commit assistant that turns intended current changes into a reviewable commit with a repository-appropriate message.

In plain words
What is it for?
It helps inspect the working tree and staged diff, choose files to stage, follow existing commit-message conventions, handle failed hooks, and split work into separate commits.
Why use it?
It reduces the chance of committing unrelated files, secrets, build output, or a message that does not match the actual changes.

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-commit 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.

Origin

This is a copy

100% identical to symphony-commit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit

Goals

  • Produce a commit whose subject and body match the actual staged diff and the session's intent.
  • Follow the repo's existing convention (run git log --oneline -20 first; conventional-commit prefixes are common but the leading-identifier style — SYM-31: etc. — also appears).
  • Never --no-verify. If a hook fails, fix the underlying problem and create a new commit.

Inputs

  • git status, git diff, git diff --staged for actual changes.
  • Recent commit messages on the branch and in origin/main for style.
  • The Symphony Workpad on the current Linear issue for scope/intent.

Steps

  1. Inspect: git status, git diff, git diff --staged.
  2. Stage intended changes by name (git add <paths>). Avoid git add -A / git add . — they sweep in .env, credentials, large binaries, or artifacts you didn't mean to ship.
  3. Sanity-check newly staged files. Build artifacts, logs, screenshots, .symphony-workspace-ready, and locally injected fallback skills under .agents/skills/symphony-* or .claude/skills must stay unstaged unless the issue explicitly asks to install or change Symphony skills. Exception: .symphony/screenshots/<name>.png is intentionally staged only by the symphony-screenshot skill's temporary evidence commit (which also --no-verifys, the only place that's allowed); that skill then creates a cleanup revert commit so the files do not remain in the latest tree while the evidence commit remains in branch history.
  4. Pick a subject (≤ 72 chars, imperative mood, no trailing period). Match the dominant style on the branch — usually <TYPE>(<scope>): <summary> or <IDENTIFIER>: <summary>.
  5. Write the body via heredoc so newlines are literal:
    • One short paragraph (the why, plus tradeoffs if non-obvious).
    • Optional bullets summarizing what changed across multiple files.
  6. Verify the message describes only what's staged. If the message and the diff disagree, fix the index — not the message.
  7. Run git commit -F <file> (or the heredoc form) so newlines are real, not literal \n.

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.
