Workflows

What it does

When your agent uses it

• Requests workflow execution
• Multi-agent orchestration

Example prompts

• “/workflows”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Inspect the task and repository before you choose the work list.
2. 2Confirm the provider, model, and reasoning tuple from the live catalog.
3. 3Write the smallest workflow that gives the requested coverage.
4. 4Validate the exact source before execution.
5. 5Start the background run.
6. 6Emit the returned workflow preview directive exactly once.
7. 7Use compact status for progress and paged history for details.

What it can do on your machine

Read from SKILL.md and the folder at commit 68a1e8b. 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 (its code samples are bash and javascript).

  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

Workflows loads about 890 tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 388 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~29

When it runs · the whole SKILL.md, loaded when a task matches

~890

With references · SKILL.md plus every file in references/, read only if the agent opens them

~5.9k

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

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.
