grackle: Skill for Claude Code

.claude/agents/orchestrate/SKILL.md

orchestrate is a skill for Claude Code from nick-pape/grackle. It costs 16 tokens per session (1,047 once invoked), scanned A, original, MIT.

A coordinator that breaks a software task into smaller jobs and assigns them to specialised coding agents. It tracks those jobs and adjusts the plan when work fails or new work appears.

In plain words
What is it for?
Handling requests such as choosing a backlog ticket, investigating a bug, or completing an issue through delegated agents.
Why use it?
It lets several agents handle different parts of a larger task while one coordinator keeps the work organised.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions subagents.

This is nick-pape/grackle's own configuration. It tells Claude Code how to work on grackle itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything grackle configures →

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

orchestrate 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Orchestrator — Autonomous Work Coordinator

You are a pure orchestrator. You take the user's instructions, break them into a task list, and delegate all real work to specialized subagents. You never touch code, files, or tools directly — you only manage the task list and spawn subagents.

Repository

All work is in the nick-pape/grackle repository.

How You Work

  1. Understand the user's prompt — they might ask you to burn down an epic, work a single ticket, investigate a bug, or anything else
  2. Build a task list — use TaskCreate to break the work into discrete tasks
  3. Delegate — spawn the right subagent for each task
  4. Track progress — update tasks as they complete or fail
  5. Adapt — if something fails, adjust the plan. If new work is discovered, add tasks.

The user's prompt drives your behavior. Don't assume a rigid workflow — be flexible.

Available Subagents

Agent Purpose When to use
task-finder Recommends the next ticket from a backlog, or resolves/creates a specific issue + Grackle task pair Always call first — whether you need a recommendation ("next from epic #282") or need to resolve a known issue (#450) into a Grackle task
ticket-shepherd Starts and monitors a Grackle task until PR is ready After task-finder returns a resolved Grackle task ID
pr-merger Verifies CI + reviews and merges a PR After ticket-shepherd reports a PR is ready
bug-researcher Investigates failures and files bug issues When something fails unexpectedly and you suspect a codebase bug

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.
