fix(agentic-engineering): bring the last five skills inside the authoring rules - #686
The authoring check for first-party skills started with five recorded exceptions. Two descriptions were over the 600-character limit, and a description is loaded in every session before a skill is chosen, so the longest ones cost the most. Three reference documents could only be reached through another reference, so a reader of the skill's entry file could not see that they exist.
What
The product-engineering description is 554 characters (was 601) and the agent-improvement description is 588 (was 718). They name the same work as before.
shared-code.md and tool-maturation.md are linked from the product-engineering entry file, and prioritization-flow.md from the agent-improvement entry file. Both entry files stay inside their 20,000-byte budget (19,963 and 19,919 bytes).
The exception record is empty, and the sentence in the lifecycle guide that pointed at the five exceptions is gone.
…ring rules
Shorten the product-engineering and agent-improvement descriptions to
554 and 588 characters, and link the three reference documents that were
reachable only through another reference from their entry files. Both
entry files stay inside the 20,000-byte budget. The exception record is
now empty.

devantler-tech/monorepo#4925 added the monorepo as a census row, so the
note that told readers to search it by hand is no longer true.

Do the shorter descriptions still load the right skill? A description decides when a skill loads, so I compared the old and the new text. Two fresh agents each got the plugin's full skill list (93 skills), one with the old two descriptions and one with the new, and the same 20 tasks. Neither knew what was being compared.
Both chose product-engineering first for the same 8 tasks: proactive improvement on a healthy product, a scripts-to-tool decision, an upstream release review, backlog triage, test coverage, a shared-library decision, a roadmap, and a benchmark.
Both chose agent-improvement for the same 5 tasks: mining a week of transcripts, a repeated permission refusal, scoring against last week, checking whether a change reduced tool errors, and two instances overwriting each other's notes.
Both left the two skills out of the same 7 tasks: red CI on main, one run reflecting on itself (self-improvement), a README, a typo, Dependabot grouping, driving dependency pull requests, and a plain refactor.
The first choice was the same on all 20 tasks. The only difference anywhere was a second skill named beside refactor on one task, which involves neither changed skill.
Installed the way a user would.gh skill install … --pin of both skills at this head into an empty folder: every reference linked from each entry file is present, including the three that were hidden before (shared-code.md, tool-maturation.md, prioritization-flow.md).
Checks. The authoring check passes with an empty exception record, and its own test still rejects every broken setup. Manifest validation, the size budget, the version-bump check, the changelog check and the digest check pass locally.
Not proven here: whether agents load these skills more or less often in day-to-day work. That needs the measured suite in #651; this trial is 20 hand-picked tasks.
Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.
The 7.6.2 update revises the agent-improvement and product-engineering skill descriptions and reference links, clears both skill-authoring exception lists, and updates the agent-improver skill hash. The changelog records the skill changes and comparison results. Plugin manifests and marketplace entries now declare version 7.6.2. The update also changes the monorepo census instructions and removes a statement about tracking exceptions in issue 680.

devantler-tech/agent-plugins#651 — This update changes skill descriptions and records a comparison across 20 tasks, but the provided issue summary says that trial does not replace its required activation evaluation.
Merge Risk: Low · previous review 878e5
The census guidance can mislead contributors who use an outdated monorepo checkout and miss the main consumers of a renamed contract. A one-line wording fix resolves it; otherwise this is safe to merge.

Explanation
Issue #680 requires the changed skill descriptions to have their activation scenarios re-run, unless an exception records why longer descriptions remain. The PR evidence supports the 554- and 588-character descriptions, the three direct links, the entry-file budgets, the empty exception record, and the 7.6.2 release updates. The reported 20-task user trial does not establish the required activation-suite result. The author states that the measured suite in #651 was not run.
Resolution
Run the activation scenarios for product-engineering and agent-improvement after the description changes, and record the results in the PR evidence or automated test output. If the scenarios cannot be run, retain an exception with the required reason instead of leaving the record empty.
Full details: Out of Scope Changes check
Explanation
The change to AGENTS.md removes a manual monorepo search instruction. The PR description identifies this line as unrelated to #680. It does not implement the five authoring-rule fixes, their validation, or the release update.

Learning: During code review in this repo: (1) For `plugins/agentic-engineering/agents/*.agent.md` (local agent-entrypoints), do NOT require upstream provenance frontmatter—assume these are authored locally; renames/edits to agent-entrypoints should remain local and not be forced through the upstream sync process. (2) For bundled skill artifacts at `plugins/*/skills/*/SKILL.md`, expect upstream provenance frontmatter to be present; do not make direct “local” edits for skill content—skill changes must originate from the upstream source and be brought in via the repo’s sync workflow.

Learning: Bundled skill artifact files at `plugins/*/skills/*/SKILL.md` are synced from upstream and must not be hand-edited locally. If you need to change a skill, update the corresponding upstream skill repository first, then pull the updated artifact into this repo using the `update-agent-skills` workflow (and review the resulting diff for the synced contents).
[warning] 132: [EA2] Autonomous Decision Making: Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
Remediation: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

The two skills are byte-for-byte what the trial above used: nothing under product-engineering or agent-improvement changed since 878e5fd5. What changed is around them: main was merged in (an updater had taken 7.6.2, so this is now 7.6.3), and the census note in AGENTS.md was reworded twice after review. At this head the authoring check, manifest validation, the version-bump and changelog checks, the digest check and the instruction-size check pass locally, and CI is green.
