What it does
Herald Autopilot is an agent skill from herald-email/herald-mail-app. Use when you want one repo-local Herald workflow to take a single bug, feature, or workflow improvement from intake through planning, isolated worktree setup, implementation, impact-based verification, branch handoff, and GEPA-style run logging.
Its SKILL.md is about 4.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 48 other files, including scripts and reference files (for example `references/gepa-improvement.md`, `references/product-truth.md` and `references/remediation-templates.json`).
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
- You want one repo-local Herald workflow to take a single bug
- Workflow improvement from intake through planning
- Isolated worktree setup
- Impact-based verification
Example prompts
- “/herald-autopilot”
Requirements
- Python 3
Workflow steps
12 steps, taken from the first numbered list in SKILL.md.
- Treat one invocation as one task.
- Ask only critical questions that change implementation or safety.
- Show a concise plan summary, then proceed unless a risky or non-obvious tradeoff needs the user's decision.
- Before tracked-file edits, explicitly ask whether the plan intentionally degrades, removes, or weakens existing behavior. No degradation…
- Record the degradation review gate with preserved behaviors and regression checks. If degradation is approved, record the approved…
- Select and record a verification budget before implementation: focused, package, visual/TUI, surface smoke, or release/hardening. Use the…
- Prefer deterministic internal/testmail virtual lab scenarios for realistic mail shapes before using private live mailboxes. Report whether…
- Run preflight for docs, SSH, and media prerequisites before baseline or implementation work begins.
- Verify baseline, then create and switch into a dedicated worktree under .worktrees/ before any tracked-file edits. Creating only a branch…
- Keep all raw machine-readable artifacts under .superpowers/autopilot/runs//.
- Stop at local branch + worktree + report. Do not push, create a PR, or merge unless the user asks.
- If the user asks to commit, merge, push, or open a PR, do that requested publish step and then surface a visible self-reflection report…
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
Ships 11 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, 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
Herald Autopilot loads about 4.9k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 1,935 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); the scripts in this folder 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 1,935 words (~4,946 tokens).
“Use this skill when the user wants to hand off one Herald task and come back later to a branch, verification evidence, and a readable report. This skill is intentionally single-task and single-worktree in v1 so it stays predictable while…”
