What it does
Finish Development is an agent skill from herald-email/herald-mail-app. Herald-specific completion workflow for requests such as "finish-development", "nice" as a repo completion command, "wrap this branch", "fast merge", "fastpass", "quick merge", "fast mode", or "commit, merge to main, delete worktree". Use when a completed Herald task should be polished or fast-passed, committed, merged into main, and its feature worktree cleaned up.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Git worktrees. The repository describes itself as: Herald is a terminal email client and inbox cleanup tool with IMAP, AI-assisted triage, MCP tools, and SSH/browser-friendly app modes.
When your agent uses it
- A completed Herald task should be polished
- Merged into main
- Its feature worktree cleaned up
Example prompts
- “finish-development”
- “as a repo completion command,”
- “fast merge”
- “/finish-development”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Preserve unrelated user changes. Do not stage, commit, merge, delete, or overwrite files that are outside the completed task.
- Treat "nice" as the final polish pass: review the diff, run formatting, run appropriate verification, and fix anything small and clearly…
- Treat "fast merge", "fastpass", "quick merge", "quickpass", "fast mode", or similar no-tests merge phrasing as Fast Mode: skip tests only…
- Ask before destructive or externally visible actions not already implied by this skill, especially pushing to a remote, force operations…
- Prefer non-interactive git commands. Avoid interactive rebases, commit editors, and merge editors.
- If a conflict, failing verification, or ambiguous dirty worktree appears, stop with the exact blocker and the safest next option.
What it can do on your machine
Read from SKILL.md and the folder at commit b097c04. 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
Shell commands in SKILL.md call:
gitmakegh
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.
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
Finish Development loads about 2.4k tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 1,221 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,221 words (~2,411 tokens).
“Use this skill as the Herald shorthand for: nice, commit, merge to main, delete the completed worktree. Keep the workflow local unless the user explicitly asks to push.”
