nx-multi-repo-migrate

Migrate several repos to a target nx version (e.g. 23.0.0-beta.25) in one coordinated pass — delegates `nx migrate` + migrations to a Polygraph child agent per repo, then pushes branches and opens linked draft PRs. Use when asked to upgrade/migrate multiple repos to a specific nx version, or when working a Polygraph session whose goal is an nx version bump across repos.

Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An expert-level, highly actionable migration runbook with strong sequencing and thorough validation for a batch operation. It is dense and long but justified by non-obvious detail; the main opportunity is splitting the largest sections and Gotchas into reference files for better progressive disclosure.

Suggestions

Move the 'Gotchas from real runs' section into a references/GOTCHAS.md file and surface a one-line pointer from the main procedure, reducing upfront token load while keeping the detail one level deep.

Break the very long step 7 (orchestrated loop) and step 8 (classic fallback) into a references/MIGRATION-MODES.md so the core Procedure stays a lean overview.

Trim conversational asides (the pharmacist analogy, '(never mention AI/Claude)') to tighten conciseness without losing operational substance.

Dimension	Reasoning	Score
Conciseness	Dense with genuinely non-obvious operational detail (env-var bypass values, version thresholds, sandbox pitfalls) that assumes Claude's competence and earns its tokens; minor trimmable asides remain (the pharmacist analogy, parentheticals like '(never mention AI/Claude)').	4 / 5
Actionability	Provides copy-paste-ready commands throughout — 'git fetch origin <base> && git checkout -B migrate-nx-<VERSION> origin/<base>', 'NX_MIGRATE_ORCHESTRATOR=true <pm> nx migrate --run-migrations --create-commits --commit-prefix=...', and a per-package-manager cheat sheet — covering the common cases concretely.	5 / 5
Workflow Clarity	An 11-step procedure with explicit validation (step 9 'Verify before declaring done', a per-repo verification checklist) and feedback loops for error recovery (crash/timeout resume, retry-clean/skip step-actions, behind-count base-drift detection) — fully satisfying the batch-operation validation requirement.	5 / 5
Progressive Disclosure	Well-organized into clear sections (Input, Procedure, Verification checklist, Gotchas) with no nested references, but the skill is monolithic — all content is inline in SKILL.md with no bundle files, and very long steps (7, 8) plus the Gotchas block could conceivably be offloaded to references.	4 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A highly specific, well-triggered description that clearly states both capability and invocation conditions for a narrow, well-defined niche. The only minor gap is keyword variation coverage within its specialized domain.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Migrate several repos to a target nx version', 'delegates nx migrate + migrations to a Polygraph child agent per repo', 'pushes branches and opens linked draft PRs' — with comprehensive coverage of the skill's behavior.	5 / 5
Completeness	Explicitly answers both what (migrate repos via per-repo child agents, push branches, open linked draft PRs) and when ('Use when asked to upgrade/migrate multiple repos... or when working a Polygraph session whose goal is an nx version bump'), with concrete trigger phrases.	5 / 5
Trigger Term Quality	Natural trigger phrases are present ('asked to upgrade/migrate multiple repos to a specific nx version', 'nx version bump across repos', 'Polygraph session'), but the narrow domain leaves a few plausible variations (e.g. 'bump nx', 'update nx across repos') uncovered.	4 / 5
Distinctiveness Conflict Risk	The combination of nx version targeting, multi-repo scope, and Polygraph child-agent delegation carves a clear niche with distinct triggers and minimal overlap risk with other skills.	5 / 5
