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 | $0.00005 | $0.00374 |
| Opus 5.5 | $0.00002 | $0.00150 |
| Sonnet 5.5 | $0.00001 | $0.00075 |
| Haiku 4.5 | $0.00001 | $0.00037 |
Grade A, and why
update-skill 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.
What it actually says
Activate the skill-writer skill before taking any other action.
Update request: $ARGUMENTS
Expected arguments:
- Skill name (or explicit path)
- Requested change(s)
- Optional scope hint:
globalorlocal
If the target skill is not clearly identifiable from the arguments, ask for the exact skill name and whether it is global or local, then stop.
Current working tree:
!git status --short
Available global skills (if present):
!ls skills 2>/dev/null || ls ~/.config/opencode/skills 2>/dev/null || true
Available local skills (if present):
!test -d .opencode/skills && ls .opencode/skills || true
Locate the target skill directory and apply the requested changes.
- Global skills live in
skills/<skill-name>/SKILL.mdwhen the workspace has a top-levelskills/directory (the Swarmforge checkout), otherwise~/.config/opencode/skills/<skill-name>/SKILL.md. - Local skills live in
.opencode/skills/<skill-name>/SKILL.md.
Constraints:
- Keep
SKILL.mdYAML frontmatter tonameanddescriptiononly. - Make minimal, focused edits consistent with the repo style.
If the change implies a new or updated slash command, locate and update the corresponding command prompt:
- Global:
commands/<command-name>.mdwhen the workspace has that top-level directory (the Swarmforge checkout), otherwise~/.config/opencode/command/<command-name>.md - Local:
.opencode/command/<command-name>.md
If no command exists but one is warranted, ask before creating it (confirm command name + expected $ARGUMENTS).
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.

update-skill is a command published in the GitHub repository CrypticSwarm/Swarmforge (3 stars, last pushed 14d ago), licensed MIT. It adds 5 tokens to every session and 374 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-08-31.
