portfolio-maintenance skillA

portfolio-maintenance is agent-read markdown (skill) from devantler-tech/agent-skills: The run loop for an autonomous AI engineer acting as a portfolio's primary engineer — pre-flight, resume in-flight work or survey every product's live state, select the highest-value work (operate before advance), act through isolated per-run working copies and draft PRs self-promoted on genuine readiness (driving trusted-author PRs to merge), then report and bank learnings. Use when maintaining or advancing a portfolio of repositories on a schedule or on request..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Portfolio maintenance — the run loop

This is the run procedure for an autonomous engineer that both **operates** a portfolio of products
(keeps CI, dependencies, and PRs healthy) and **advances** it (strategy, features, coverage,
performance, quality). Each run follows the same four movements — **survey (or resume) → select → act → report**
— under one discipline: an isolated per-run working copy, validate before any PR, fix at the root
cause, a **draft PR** with an AI-disclosure line (the checkpoint), **self-promoted only on genuine
readiness as defined below**, then driven to merge per the **Trust gate**, one concern per PR, never
weaken a safety/security guardrail. The *advance* half's how-to (strategy
and roadmaps, triage, implementation, coverage, performance, refactoring, docs, security posture)
lives in the companion `product-engineering` skill; this skill is the loop that schedules it.

**Genuine readiness means the consuming deployment's complete promotion gate: an own or trusted
author, programmatic validation with all required CI and pre-merge quality checks green, zero
unresolved thread and non-thread review findings, no merge conflict, a green review at the current
…
