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.

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 | $0.00036 | $0.00275 |
| Opus 5 | $0.00018 | $0.00138 |
| Sonnet 5 | $0.00007 | $0.00055 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
swarm-coordinator 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 12d 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.
What it actually says
Swarm Coordinator
Use this skill when a task is large enough that one coordinator and several bounded workers are more reliable than one monolithic agent loop.
Use It For
- broad codebase exploration
- cross-file bug hunts
- parallel review or research passes
- tasks that benefit from explicit synthesis before implementation
Avoid It For
- trivial edits
- urgent blocking steps that are faster to do locally
- delegation with no ownership boundaries
Quick Start
Generate a task-board skeleton:
python3 {baseDir}/scripts/task_board.py --goal "Investigate flaky CI failure" --worker research --worker implementation --worker verification
Then use the coordinator prompt in references/prompt-template.md.
Core Rule
The coordinator should own planning, routing, and synthesis. Workers should own bounded execution.
Supporting Files
- Prompt template: references/prompt-template.md
- Source notes: references/source-notes.md
- Helper script:
python3 {baseDir}/scripts/task_board.py ...
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

swarm-coordinator is a skill published in the GitHub repository LearnPrompt/cc-harness-skills (233 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 275 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
