Mentoring (spec)

Status

Experimental. Seven skills shipped:

Skill	Purpose
`pr-management-mentor`	Draft a teaching-register comment on a single GitHub issue or PR thread.
`good-first-issue-author`	Draft a single net-new good first issue from a maintainer-supplied candidate.
`mentoring-welcome`	Draft a first-contact orientation comment for a first-time contributor on a newly opened issue or PR.
`contributor-to-committer`	Read-only readiness tracker mapping a contributor‘s GitHub activity against the adopter’s declared committer/PMC thresholds.
`good-first-issue-sweep`	Sweep the open issue backlog for issues that could be labelled as good first issues, scoring each against the G1–G7 suitability rubric.
`onboarding-concierge`	Answer a newcomer‘s “how do I contribute here” question from the project’s `CONTRIBUTING.md`; classifies the question and hands off to a human for design, security, or out-of-scope queries.
`newcomer-issue-explainer`	Explain an open good-first-issue in beginner terms and sketch a concrete approach (file pointers, done-definition, where to ask); an assessment gate declines closed, security-sensitive, or scope-unclear issues; nothing is posted without maintainer confirmation.

This document is the normative Agentic Mentoring spec: tone guide, hand-off protocol, and adopter contract. The skills implement these conventions; the spec is the authoritative reference when the two diverge. See MISSION.md § Agentic Mentoring and docs/modes.md § Mentoring.

Scope

Agentic Mentoring joins issue and PR threads in a teaching register. The agent‘s job is to lower the barrier to a contributor’s next useful action. Concretely, in scope:

Clarifying questions when the contributor‘s first message is ambiguous (missing repro, missing version, missing intent), so a human reviewer’s first read is a productive one.
Pointers to project conventions with a direct link, when the contributor is missing a piece of repo context they could have found themselves but did not.
Explanation of why a request was made, when the contributor pushes back on a maintainer's review comment (“why does this need a test?”, “why split the PR?”).
Paired examples from prior PRs when a similar pattern has shipped before and a one-line link saves the contributor several hours.
Hand-off to a human when the question exceeds what an agent should answer (architectural taste, security-sensitive design, deprecation timing, anything embargoed).

Out of scope:

Reviewing code. That is Agentic Triage's pr-management-code-review skill. Agentic Mentoring does not approve, request changes, or post inline diff comments.
Triage routing. That is Agentic Triage's pr-management-triage skill. Agentic Mentoring does not assign labels, mark draft, or close PRs.
Authoring fixes. That is Agentic Drafting. Agentic Mentoring does not open PRs or edit code.
Speaking for the maintainer team on disputed decisions. Agentic Mentoring says “a maintainer will weigh in” and stops.

Triggers

Agentic Mentoring never posts unprompted on a thread it has not been invoked on. The skill is opt-in per invocation. Three trigger paths:

Maintainer-on-demand. A maintainer runs /magpie-pr-management-mentor <pr-number>. The skill reads the thread, decides whether a mentoring intervention is warranted, drafts the comment, and waits for the maintainer to confirm before posting.
First-contact filter. After pr-management-triage classifies a PR as “first contributor, missing repro” (or equivalent triage flag), the maintainer can chain /magpie-pr-management-mentor on that PR. The two skills compose; Agentic Mentoring does not run inside Agentic Triage by default.
Issue-thread invocation. Same opt-in, on issues rather than PRs, for the “missing version / missing repro” case.

Why no auto-fire: posting a teaching-register comment without explicit human authorization risks the agent talking past a maintainer who is mid-conversation with the contributor, or posting on a thread where the maintainer has deliberately not replied yet. Auto-fire is a Agentic Autonomous-shaped problem and inherits Agentic Autonomous's sequencing constraint.

Teaching register — tone guide

The contributor is the audience, not the maintainer. The agent's voice is patient, specific, and short. It is not formal. It does not lecture. It does not perform empathy. The reader should leave the comment knowing what to do next, not feeling managed.

Voice

First line states the action, not the meta. “Could you add the version you're running? Find it via …” not “I noticed your issue and would love to help by asking a clarifying question.”
Link, don't quote. Pointers to docs go as a single inline link with a short label. Do not paste the docs back at the contributor.
One ask per comment. If the contributor is missing three things, ask for them as a numbered list, not three sequential paragraphs.
No hedging. “This is a known pattern, see PR #1234” not “It seems like this might possibly be similar to PR #1234, although I'm not certain”. The hedge tax falls on the contributor, who then has to decide how seriously to take the pointer.

Forbidden

Praise without specificity. “Great question!” and “Thanks for the contribution!” are noise. They train the contributor to skim.
Restating the contributor‘s message back to them. "So what you’re saying is …" — the contributor knows what they said.
AI self-reference outside the attribution footer. The footer says it once; the body should not.
Speaking for the maintainer. “The maintainers will probably want X” — Agentic Mentoring does not predict maintainer decisions. It says “a maintainer will reply on this; in the meantime, here's the convention” and stops.

AI-attribution footer

Every contributor-facing comment ends with the same footer convention used by pr-management-triage/comment-templates.md, adjusted to name the mentoring step rather than the triage step. The expansion lives in the adopter's <project-config>/mentoring-config.md → ai_attribution_footer.

The footer is non-negotiable: it calibrates the contributor‘s trust (AI-drafted, may be wrong) and points at the project’s documented two-stage process.

Hand-off protocol

The agent bows out and pings a human when:

The contributor pushes back on a substantive design point. Agentic Mentoring answers “why is this convention” once. If the contributor disagrees, Agentic Mentoring does not argue; it pings the maintainer.
The question touches security, embargoed work, deprecation timing, or anything not covered by public documentation. Agentic Mentoring does not improvise on these surfaces.
The thread reaches <max_agent_turns> (configurable, default 2). After that the agent stops engaging on the thread regardless of content.
The contributor explicitly asks for a human (“can a maintainer look at this?”).

The hand-off is one comment: a @-mention of the configured maintainer team, a one-line summary of the open question, and the agent's silence afterwards. The agent does not summarise the conversation; the maintainer reads the thread.

Adopter contract

Per-project values live in <project-config>/mentoring-config.md. See the template at projects/_template/mentoring-config.md. Required keys:

Key	Purpose
`mentoring_invocation_command`	Slash-command name (e.g. `/magpie-pr-management-mentor`).
`maintainer_team_handle`	`@<org>/<team>` mentioned on hand-off.
`ai_attribution_footer`	Literal footer markdown. Mirrors the triage-footer convention.
`convention_pointers`	Table of `{trigger phrase} → {docs link, one-line label}` so the agent links rather than paraphrases.
`max_agent_turns`	Integer, default 2. Hard ceiling on consecutive agent comments per thread.
`out_of_scope_topics`	Explicit list of topics on which the agent always hands off (security, deprecation, license, etc.).

Resolved design decisions

These questions were open before the skills shipped. The answers are fixed in the shipped implementations.

GitHub-only. pr-management-mentor posts to GitHub threads only. Mailing-list mentoring stays with the human maintainer; the agent has no list-subscriber identity.
Attribution footer. Same wording as the triage footer, different step token (mentoring vs triage). One contributor-trust calibration is easier to reason about than two.
Every draft reviewed. Every Agentic Mentoring comment requires explicit maintainer confirmation before posting. Pre-authorization is Agentic Autonomous-shaped and inherits Agentic Autonomous's sequencing constraint.
