Why

Agents writing the README of a small tool still repeated its input rules, explained how it works inside and reported how it was tested, so the first useful step was hard to find. The README skill said to keep such detail out, but not what the page should hold instead.

What

The README skill now names the four things such a page holds: what the tool is for, one working example, what goes in and what comes out, and the limits that change what a user does. It says to state each requirement once, to link to the full reference instead of copying it, and to move internals and test records to where maintainers look, while safety and setup steps stay. The documentation-site skill and the product-engineering skill carry the same rule for user guides and for documentation written alongside a change.

Fixes #687

… needs

write-readme now says what the README of something people call holds: what it
is for, one working example, what goes in and what comes out, and the
constraints that change what a user does. Each requirement is stated once, the
full contract is linked instead of copied, and internals, design reasons and
test records move to a design note, the contribution guide or the review.
Safety and setup steps stay.

product-documentation carries the same rule for user guides, and
product-engineering for documentation written alongside a change.

Fixes #687

User trial at 5ab39b723c34cde079ff98a965c7adb80b9df3a4

The representative task was the README of devantler-tech/guard-installed-skill-edits-action: 193 lines, with its requirements stated up to three times and a 60-line section on internals. A fresh agent, given only the README skill and the repository, rewrote it: once with the skill on main, once with this change. It was told nothing about being brief. Then a different fresh agent, given only the resulting documentation, had to set the action up for a repository with its own skill folder, an updater bot and a merge queue, and report what it could not find, what was repeated and what it did not need.

README today Rewritten with the skill on main Rewritten with this change
Length in lines 193 130 118
Lines read before the reader could write the workflow 107 103 85
Lines the reader did not need as a user about 99 about 36 about 31
Facts the reader found stated more than once 14 8 8
"A check fails with UNKNOWN. What now?" causes pieced together from three sections three causes, then a pointer to another page each message with its fix, from one table

All three readers wrote a correct workflow with the three inputs set, and all knew the check must be made required before it blocks a merge.

What changed in the output, beyond length:

  • With the skill on main, the rewrite still had a "How it works" section, a paragraph restating the input rules under the inputs table, and the yq requirement in two sections.
  • With this change, the requirements sit beside the example and are stated once, the inputs table links to the action definition, and internals and release recovery moved to their own pages with one link each. Nothing a user needs was dropped: the full-history checkout, the right yq, the merge-queue limit and the required-check step are all there.
  • The rule that safety stays did its job. The rewrite added a warning the README did not have: a wrong skill-root makes the check pass without examining anything.

A second task checked that the skill does not damage a README that is already short: setup-agent-skills-action, 90 lines. The result has 63. It moved the example up, removed three restated rules and the release procedure, and added what the action changes and when it fails, including that an already installed skill is replaced together with local edits to it.

Limits of this trial:

  • The count of repeated facts did not drop compared with the skill on main (8 and 8). What is left are cross-references, such as a table row and the log message for the same case.
  • The first run used a draft of this text and led to three clarifications: what to show when a tool returns nothing, where release procedures go when there is no contribution guide, and that a sentence restating a table row counts as a repeat. The figures for "this change" come from a second run at the final text.
  • The agents ran nothing and had no network, so the commands, links and badges in the rewritten pages are unchecked. The rewrites are not part of this pull request.
  • Every reader had to guess how to exempt an updater in a merge queue: the action's README says to do it, not how. That is a gap in that README, not in the skill, and is filed as Say how to exempt the updater's pull requests in a merge queue guard-installed-skill-edits-action#16.
  • Not proven here: whether agents load the skill when they write a README as part of other work (Measure skill activation and adherence with a claude plugin eval suite #651 measures loading). The two sentences added to product-engineering are for that case and were not trialled.

Size: write-readme grows from 5,824 to 7,991 bytes and product-documentation from 5,894 to 6,231. product-engineering is at 19,992 of its 20,000 bytes. No description changed.

Walkthrough

The plugin’s documentation skills now give more specific guidance on README content, avoiding repeated instructions, and keeping implementation notes and validation records out of user-facing guides. The changelog records these updates. Plugin version declarations change from 7.6.3 to 7.6.4.

Merge Risk: Low · previous review 5ab39

This documentation-guidance update is safe to merge. One instruction is slightly too broad and could lead agents to leave reader-needed architecture details out of maintained docs, so a small wording tweak is worth making.

Full details: Linked Issues check

Explanation

Issue #687 requires concise, plain-English, usage-focused documentation; canonical links instead of repeated rules; retained safety and setup guidance; and a representative README usability check. write-readme/SKILL.md now defines purpose, one working example, inputs and outputs, and user-relevant constraints. It directs authors to state each rule once, link to canonical contracts, exclude internals and author-only validation records, and retain safety and setup steps. product-documentation/SKILL.md and product-engineering/SKILL.md apply the same rule to user guides and change documentation. The PR reports representative README trials that checked first-use placement and unnecessary repetition.

Full details: Out of Scope Changes check

Explanation

The changed skill files directly implement issue #687. The changelog and plugin version updates support release of those skill changes. The available PR summary shows no unrelated product or behavior changes.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 0 files. (9 skipped: 9 unsupported.)

## Conventions
11. **Improvements to a generic role belong upstream of the consumer that found them.** This
    marketplace ships role behaviour that many deployments install, so a fix written into one
    consumer's own copy or overlay of a bundled agent is drift: it stops inheriting upstream fixes and
    grows what every dispatch loads. Route by asking whether the change would have to be rewritten to
    install the role on a different portfolio — if not, it belongs in the definition's own upstream
    (this repository for `plugins/*/agents/*.agent.md`, this repository for an authored skill, or the repository named in an external skill's `metadata.github-repo`). The `agentic-engineering`
    [plugin README](plugins/agentic-engineering/README.md) states this for its consumers, and both of
