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.

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 | $0.00056 | $0.00418 |
| Opus 5 | $0.00028 | $0.00209 |
| Sonnet 5 | $0.00011 | $0.00084 |
| Haiku 4.5 | $0.00006 | $0.00042 |
Grade A, and why
swarm 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 7d 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
Read .opencode/skills/swarm/SKILL.md for the source behavior model, then adapt it to Codex.
Codex-specific execution notes:
- Treat this as a workflow posture, not an instruction to call OpenCode
/swarmcommands. - Use parallel local reads/searches where safe.
- Use
update_planfor visible task tracking on substantial work. - Add independent review pressure through
$qa-sweep,$swarm-pr-review, or self-critic checks when subagents are unavailable. - Keep the user looped in with short progress updates during longer work.
- For any task that edits code, tests, docs, package metadata, release notes, or skill files, final completion requires:
- objective validation evidence,
- independent implementation reviewer approval on the actual latest diff,
- separate critic approval after reviewer approval,
- no unresolved
NEEDS_REVISION/BLOCKEDitems, and - no edits after those approvals.
- Record reviewer and critic verdicts in durable task artifacts. For issue-tracer
work, use
08b-implementation-review.mdand09-final-critic.md; otherwise use task-local review artifacts unless the repo forbids artifacts. - Explorer subagents, a plan critic, passing tests, or self-review do not satisfy the final implementation-review gate when subagent delegation is available and swarm work is authorized.
For implementation tasks, prefer $swarm-implement; for fresh PR review, prefer
$swarm-pr-review; for known PR feedback closure, prefer
$swarm-pr-feedback; for bug tracing, prefer $issue-tracer.
What ships with it
1 file 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 is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (463 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 418 once invoked, about $0.0003 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.
