At a glance

Hand a spec that is mid-implementation to another machine or another agent.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Handoff Spec is an agent skill from dzhng/skills. Hand a spec that is mid-implementation to another machine or another agent.

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Reusable AI agent skills for software factories: explore ideas, write specs, implement, review, and run autonomous research. Works with Claude Code, Codex, and other… The licence is MIT.

Example prompts

  • “/handoff-spec”

What it can do on your machine

Read from SKILL.md and the folder at commit d513228. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Handoff Spec loads about 349 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 222 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~349

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Handoff Spec

I'm moving this spec's work to another machine or another agent. The next session starts cold: it has the repository and nothing else. It has none of this conversation, none of this machine's files and none of your memory. Leave the spec so that session can carry on as if it had been here.

Collect what this session knows and the spec doesn't yet say, from the discussion and from the work itself, and put it in the spec:

  • what is done, what is half-done and exactly where it stopped, and what is next;
  • what I decided or corrected along the way, and how I want the work done;
  • calls you made where I was silent, and anything still waiting on me;
  • what is known to be broken or unverified, with what you already found out about it;
  • anything that lives only on this machine and the next session needs: unpushed branches, uncommitted work, scratch results worth keeping.

Write it into the spec's own handoff, in place: the spec stays one current account, not a transcript with a new note on top. Then push, so everything the spec points at exists on the remote.

Done when a fresh agent, given only the repository, would pick the same next step you would, and would not repeat a question I've already answered.
