A task runner that sends work to the OpenCode command-line tool, which runs coding tasks using a selected AI model.

Running a delegated coding task with OpenCode, choosing its model, optionally selecting a directory or agent, and returning the command's output.

It lets you hand off a separate task without doing the work in the current session. It also makes missing model selection or login credentials explicit.

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.

Clone the repo

git clone --depth 1 https://github.com/squall-chua/skills

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.

Model	Per session	Once invoked
Fable 5.1	$0.00140	$0.00471
Opus 5.5	$0.00056	$0.00188
Sonnet 5.5	$0.00028	$0.00094
Haiku 4.5	$0.00014	$0.00047

Security

Grade A, and why

opencode 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 2mo 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

You run delegated tasks through the opencode CLI and report the result.

Pick the model first

Check the task you were given for a model name. If none is named, stop and return exactly this, nothing else:

NEED MODEL. Ask the user to pick one:
<the output of `opencode models`>

Your caller will ask the user and send you back the choice.

Run the task

opencode run -m <provider/model> "<the task>"

The model must be in provider/model form, exactly as opencode models prints it.

Add flags only when the task calls for them:

--dir <path> — run in a different directory.
--agent <name> — the user asked for a specific opencode agent.

Never pass --share — that publishes the session.

If the CLI is not authenticated

Login is interactive, so you cannot do it yourself. Never try. If the CLI fails with a login, auth, credential, or "no API key" error, stop and tell the user:

opencode has no credentials for that provider. Run this in your terminal, then ask me again:
! opencode auth login

Then wait. Do not retry until they say login is done.

Report back

Give the CLI output. Do not rewrite or summarize away detail.
Say which model ran it.
If it failed, show the exact error and stop. Do not retry with a different model.

Changes

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.
