opencode-dockerized: Skill for Claude Code

.opencode/config/skills/handoff/SKILL.md

handoff is a skill for Claude Code, OpenCode from mazumba/opencode-dockerized. It costs 19 tokens per session (198 once invoked), scanned A, a copy of handoff, MIT.

A handoff-document tool for recording the current conversation so another coding agent can continue the work. The document is saved outside the project workspace and removes sensitive information.

In plain words
What is it for?
It helps transfer unfinished coding tasks between sessions or agents, including the requested focus and suggested next actions.
Why use it?
A new agent may otherwise lose the task's context, decisions, and next steps. It also points the next agent to relevant skills and existing artifacts without copying them.

Skill for Claude CodeOpenCode

Written for Claude Code and OpenCode: disable-model-invocation in frontmatter, but also installed under .opencode/.

This is mazumba/opencode-dockerized's own configuration. It tells Claude Code and OpenCode how to work on opencode-dockerized 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 opencode-dockerized 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

handoff 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 2d 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.

Origin

This is a copy

100% identical to handoff — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Write a handoff document summarising the current conversation so a fresh agent can continue the work. Save to the temporary directory of the user's OS ($TMPDIR, else /tmp; %TEMP% on Windows) - not the current workspace.

Include a "suggested skills" section in the document, naming which skills the next agent should call the Skill tool for.

Do not duplicate content already captured in other artifacts (specs, plans, ADRs, issues, commits, diffs). Reference them by path or URL instead.

Redact any sensitive information, such as API keys, passwords, or personally identifiable information.

If the user passed arguments, treat them as a description of what the next session will focus on and tailor the doc accordingly.

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.
