Dynamo PR Description

What it does

When your agent uses it

• Writing a pull request description
• Cleaning up a PR body
• Generating a review-ready summary from a diff in the Dynamo repo
• The user says write a PR

Example prompts

• “write a PR”
• “PR description”
• “prep this for review.”
• “/dynamo-pr-description”

Workflow steps

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

1. 1Read the diff (staged changes, commit history, or user-provided summary).
2. 2Identify the why -- what problem does this solve?
3. 3Fill .github/PULL_REQUEST_TEMPLATE.md from the diff and context.
4. 4For each declaration checkbox, only check it if you've verified it's true.
5. 5Write the release note from the user's perspective (one sentence, or N/A).
6. 6Leave (FILL ME IN) placeholders for anything you can't determine from the diff.

What it can do on your machine

Read from SKILL.md and the folder at commit 8cadc02. 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 markdown).

  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

Dynamo PR Description loads about 880 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 337 words of instructions outside code blocks.

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

~89

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

~880

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.
