What it does
Maintainer Persona is an agent skill from mizchi/skills. Write an issue or PR for a repository you do not own so its maintainers can triage it. Measures the target's own history (reviewers, gates, body length, headings, language, how first-time PRs fare) into an editable persona file, branches by context (OSS first-time / OSS returning / another team inside your org), drafts in Japanese and translates only after approval when the target writes English, checks with a fresh reader and a slop lint baselined on the maintainers' own PRs, and gates the send. Use when filing…
Its SKILL.md is about 6.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts (for example `README.md`, `scripts/check-draft.ts` and `scripts/check-draft_test.ts`).
It sits in Development, covering Failing and flaky tests and Linting and formatting. The repository describes itself as: Agent skills by mizchi, distributed via APM.
When your agent uses it
- Filing upstream issues
- Failing-test PR to another project
- Rewriting a submission that was ignored
Example prompts
- “/maintainer-persona”
Requirements
- Node.js
Workflow steps
9 steps, taken from the step headings in SKILL.md.
- Measure
- Complete the persona by hand
- Branch by context
- Verify the facts before writing
- Draft
- Approval
- Translate (the kind's language is en or mixed)
- A fresh reader
- Gate and send
What it can do on your machine
Read from SKILL.md and the folder at commit 62f5808. 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 7 files in scripts/ (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
ghnodegitpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
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
Maintainer Persona loads about 6.4k tokens when it runs. Until then it costs about 165 tokens; SKILL.md has 3,723 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 3,723 words (~6,407 tokens).
“The shape of a submission is a property of the target repository, not of the finding. Body length, title convention, whether a test is expected, who reviews and how outsiders are treated all differ between repositories, and all of them…”
