skill-audit loaded roughly 4,268 words of rubric on every run, most of it criteria for findings a clean skill never triggers. The auditing guidance moves into finding-criteria.md, read only when a finding is actually raised, cutting a clean audit to about 999 words. The named-skill exemption is replaced with properties, so the rubric stops carrying a list that ages the moment a skill is renamed. apm-workflow's `type:` trap sat in one flow while biting several, so it is promoted to a common gate reachable from all of them; its claim to be self-contained was untrue once it started routing to apm-install. skill-author's contract had drifted from body-discipline.md and is realigned, and agent-audit's field inventory is brought in line with the same split.

# Patterns Reference
|
|
|
|
Upstream source: agentskills.io — best-practices (instruction patterns), specification.
|
|
|
|
Read this when judging the **patterns** dimension: whether each instruction construct a skill uses
|
|
is the right construct for the job and is correctly formed. Formation, not content — a Gotcha's
|
|
*content* is judged in `references/body-discipline.md`.
|
|
|
|
## The constructs and when each is right
|
|
|
|
| Construct | Right when | Wrong when |
|
|
|---|---|---|
|
|
| Gotchas | An environment fact contradicts a reasonable default | Used as a summary of the steps below |
|
|
| Prescriptive sequence | The operation is fragile and flag order or exact arguments must not change | Several approaches are equally valid |
|
|
| Checklist | A multi-step workflow the agent must complete in order | A single step dressed up as a list |
|
|
| Conditional reference | Detail is needed on one branch only | The reference is needed on every run and is loaded blind |
|
|
| Output template | The agent must emit a specific format a caller consumes | The output is prose nobody parses |
|
|
|
|
## Formation rules
|
|
|
|
**Gotchas** sit near the top of the body, before the steps that would otherwise walk into them.
|
|
Placement late in the body is a SUGGESTION, not a FAIL — the content is still correct, it is just
|
|
read after the mistake.
|
|
|
|
**Prescriptive sequences** that quote a fenced block inside another markdown block must escape the
|
|
inner fence as `` \`\`\` ``. An unescaped inner fence terminates the outer block and the remaining
|
|
instructions render as prose.
|
|
|
|
**Conditional references** state a specific trigger, naming a file that exists in the skill's own
|
|
`references/` directory:
|
|
|
|
```text
|
|
If the API returns a non-200 status, read `references/api-errors.md`.
|
|
```
|
|
|
|
That block is fenced because the filename in it is illustrative — an unfenced `references/` pointer
|
|
in a `SKILL.md` body must resolve on disk or the ADR-0020 gate reports a hard ERROR. The generic
|
|
form — pointing at the directory and hoping — defeats
|
|
progressive disclosure, because the agent either loads everything or loads nothing.
|
|
`Kyberforge.PaddingPhrase` catches the common generic phrasing deterministically; other malformed
|
|
forms are judgment.
|
|
|
|
**Output templates** belong in the body when the agent must emit them on every run, and in
|
|
`references/` when only one dispatch branch produces that output. A template inlined for a branch
|
|
most invocations never take is body-discipline padding.
|
|
|
|
The FAIL and SUGGESTION criteria for this dimension live in `references/finding-criteria.md`,
|
|
which Step 3 loads on every run.
