symphony-skill

symphony-skill is a skill for Claude Code, Codex from cskwork/oh-my-symphony. It costs 55 tokens per session (2,682 once invoked), scanned A, original, Apache-2.0.

A coordinator for coding-agent work that reads Kanban tickets and assigns them to coding tools in separate workspaces. Kanban is a board where work moves through stages such as planned, active, and done.

In plain words
What is it for?
Use it to manage tickets, run the service or terminal interface, customize workflow lanes, delegate large requests, set up repositories, and investigate worker failures.
Why use it?
It gives a repeatable way to run, configure, and monitor agent-led development work across a project.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 146
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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-skill scanned grade A with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (monorepo/scripts/setup-monorepo.sh, oneshot/templates/bootstrap.sh, oneshot/templates/playwright-qa.spec.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Using Symphony

Symphony is a polling orchestrator that reads Kanban tickets and runs a coding-agent CLI (Codex, Claude Code, Gemini, AGY/Antigravity, Kiro, OpenCode, Pi, or Prime Agent) against each ticket in an isolated workspace. This file is the single operator router: classify the request, load only the matching reference, then act.

Start by reading the target WORKFLOW.md and one or two real kanban/*.md files. Symphony behavior is workflow-specific, and forks commonly customize lanes, prompts, hooks, workspace roots, and agent backends.

Route

State the route in one line, then open only the reference that route needs.

Branch-specific subfolders under oneshot/ and monorepo/ intentionally do not have their own SKILL.md. They provide templates, scripts, and deep references for this router.

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.
