chore(aim): sync instruction modules to AIM 0.11.0 and vendor agent skills

[tablackburn]

What

Syncs this repository's AIM instruction modules from none to 0.11.0. Copied from instruction-templates/ (the downstream-distributed copy), leaving repository-specific.instructions.md alone per AIM's Content Preservation Rules.

Why now

The whole fleet had drifted 1-3 minor versions behind, which is why none of these repositories had the guidance below.

What it brings in

The headline is a new Pester section in powershell.instructions.md:

Set-ItResult -Skipped (and -Inconclusive) ends the It block immediately [...] a trailing return is unreachable dead code; do not add one. Reviewers, including automated ones, recurrently suggest the redundant return.

That last sentence is not hypothetical -- Copilot's review bot suggested exactly that redundant return on ReScenePS #35, and it was measured wrong under Pester 6.1.0 before this rule was found. The section also says to prefer -Skip:$condition for conditions known at discovery time and reserve Set-ItResult for runtime-only ones.

Also included: a Line Continuation section forbidding backtick continuation, revised Path-vs-Directory naming, and a rewritten update.instructions.md covering skill vendoring.

Verification

Before syncing, every instruction file in this repository was diffed against the AIM release it claimed, to catch local edits a blind overwrite would destroy. This repository had none -- it matched its stamped release exactly, so the sync is purely mechanical.

Documentation only. No code, build, or CI changes.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

📝 Walkthrough

Walkthrough

The pull request expands repository instructions for development, authoring, testing, releases, and synchronization. It adds enabled, pinned psake and PowerShellBuild Agent Skills with attribution, routing documentation, build examples, CI/CD references, and migration guidance.

Changes

Instruction Guidance

Layer / File(s)	Summary
Development workflow guidance instructions/agent-workflow.instructions.md, instructions/contributing.instructions.md, instructions/git-workflow.instructions.md	Adds clarification guidance, changes the instruction template location, and expands branch, commit, pull request, review, and merge procedures.
Authoring and validation rules instructions/markdown.instructions.md, instructions/powershell.instructions.md, instructions/shorthand.instructions.md, instructions/testing.instructions.md	Updates numbering, fenced-code rules, PowerShell conventions, shorthand examples, build-system checks, analysis rules, and critical-path testing guidance.
Release procedures instructions/releases.instructions.md, instructions/github-cli.instructions.md	Requires pull request completion before releases and uses a temporary notes file with --notes-file for release creation.
Agent Skills synchronization instructions/update.instructions.md, AGENTS.md, CLAUDE.md, aim.config.json, .agents/skills/NOTICE.md	Adds skill configuration, pinned vendoring, overwrite handling, attribution, routing through AGENTS.md and CLAUDE.md, and validation steps.
Vendored build skills .agents/skills/psake/*, .agents/skills/powershellbuild/*	Adds psake and PowerShellBuild guidance, build examples, task configuration, CI/CD workflows, troubleshooting, build patterns, and psake v5 migration documentation.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk:🟡 Moderate · up to 621b4

The PR adds vendored skills and instruction updates, but several examples could cause generated builds or deployments to use incompatible dependencies, skip required setup, continue after failed commands, or miss rollback handling. Additional naming, branch, release, and command examples remain inconsistent, so the PR is not merge-ready until these bounded documentation and example issues are fixed.

Pull request overview

This PR mechanically syncs this repository’s AIM instruction modules to AIM 0.11.0, updating the documentation guidance for agents (no runtime/code changes).

Changes:

• Expands update.instructions.md with a new skills configuration schema and a procedure for vendoring Agent Skills into .agents/skills and routing them via AGENTS.md + a CLAUDE.md bridge.
• Significantly extends powershell.instructions.md (common mistakes, Path vs Directory naming, parameter-call guidance, line continuation rules, build-system preference, PSScriptAnalyzer suppression rules, and new Pester skip guidance re: Set-ItResult).
• Cleans up and aligns several other instruction modules (testing/tooling discovery, markdown ordered-list numbering, releases + gh CLI guidance, workflow guidance, shorthand list).

140-145: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Validate the vendored skill before routing it.

Lines 140-145 require locating SKILL.md and copying the folder, but they do not validate the skill format. The checklist at Line 214 also stops at vendoring and routing. A malformed SKILL.md can pass this procedure and remain unusable. Validate the required Agent Skills frontmatter and the complete directory before updating AGENTS.md; record that check in the checklist. The Agent Skills specification requires SKILL.md plus name and description frontmatter. (github.com)

Resolving the open review threads before merge, since branch protection requires conversation resolution. Recording why, rather than closing them silently.

Almost all of them are against content this repository copies in rather than owns:

• Vendored Agent Skills (.agents/skills/psake/**, .agents/skills/powershellbuild/**) are copied verbatim from psake/psake-llm-tools at the tag pinned in aim.config.json. NOTICE.md and step 7.2 of update.instructions.md both say never to edit them in place -- re-sync from upstream instead -- so acting on a finding here would mean doing the one thing that is not allowed.
• Instruction modules (instructions/*.instructions.md, except repository-specific) are synced from tablackburn/ai-agent-instruction-modules. CodeRabbit is installed there and reviews every human PR, so this content is already reviewed where it lives and where a fix can actually land. Fixing it here would fork the repository from the template and be overwritten by the next sync.

The .coderabbit.yaml added in this PR stops both from being reviewed downstream in future, so this is a one-off cleanup rather than a recurring cost. Verified on a full review pass: 5 files selected, 18 ignored by path filters.

Findings against files this repository does own -- aim.config.json, AGENTS.md, CLAUDE.md, .agents/skills/NOTICE.md -- were handled individually. One was fixed (the vendored-skills license link pointed at a moving branch while the skills were pinned to a tag); the rest were answered inline, and the two schema gaps worth pursuing are recorded for AIM: external instruction sources cannot be pinned to a tag or digest at all, and skills.vendorPath is configurable while native discovery is hard-coded.
