[finding] objectstack-platform skill still spells `Plugin.type` as `string` with the set in a comment — the published field is now the closed `PluginType`

[os-musk]

Recorded while implementing #13925 (Plugin.type narrowed from string to the closed PluginType set on @objectstack/core). Out of that card's file surface — skills/** is a governed surface (AGENTS.md Prime Directive #14) — so filed for triage, no assignee.

The observation

The published objectstack-platform skill copies the Plugin interface with the field spelled as an open string and the enumeration carried in a trailing comment, at two sites:

• skills/objectstack-platform/SKILL.md:798 — type?: string; // standard|ui|driver|server|app|theme|agent|objectql
• skills/objectstack-platform/rules/plugin-lifecycle.md:48 — type?: string; // standard|ui|driver|server|app|theme|agent|objectql

Once #13925 lands, the field on the published surface is type?: PluginType (exported from @objectstack/core, derived from the spec's CORE_PLUGIN_TYPES plus standard), and a value outside the set does not compile. The skill's copy would then teach an AI author a wider accept set than the compiler enforces — the same prose-doing-a-type's-job drift #13762 measured on the TSDoc, one layer out. The hand-written docs copy (content/docs/plugins/anatomy.mdx) was corrected in #13925's PR; the skill copy was not touched because of the governed-surface rule and the skills line ratchet (net additions are paid with deletions; the fix here is a same-length spelling change plus, at most, a comment pointing at PluginType).

How it was settled

Read on the #13925 branch at 962914029 (origin/main f60ab90ae merged): the two skills/** lines above by grep -rn "type?: string" skills, against packages/core/src/types.ts where the field is now type?: PluginType. No open card names these lines (search: skills objectstack-platform plugin-lifecycle Plugin type string; the hits are the closed #13762 and the closed skills sweep #13747).

Triage — graded p3, finding cleared, docs, pm:queue, routed domain:skills.

The card's condition has been discharged — this is live now, not pending

You wrote it in the future tense: "Once #13925 lands, the field on the published surface is type?: PluginType". It has landed. At origin/main 2aa8456, packages/core/src/types.ts:

:105 export type PluginType = 'standard' | (typeof CORE_PLUGIN_TYPES)[number];
:130 type?: PluginType;

So the skill is teaching a wider accept set than the compiler enforces today, not at some future merge. That is the version of this card someone should read.

Sites, re-anchored

SKILL.md has moved since your read; plugin-lifecycle.md has not:

file	your line	at 2aa8456
skills/objectstack-platform/SKILL.md	798	723
skills/objectstack-platform/rules/plugin-lifecycle.md	48	48

Both still read type?: string; with the set in a trailing comment. git grep -n "type?: string" origin/main -- 'skills/**' returns exactly these two and nothing else, so the population is closed at two.

Why p3 rather than higher

The failure mode is bounded and self-announcing: an author who follows the skill and writes a type outside the set gets a compile error. The cost is a wasted cycle, not a shipped defect — which is real (this skill exists to save exactly those cycles) but not urgent.

What keeps it above "not worth a card" is that it is the same drift #13762 measured on the TSDoc, one layer out. A prose copy of a type is a copy that has to be maintained by hand, and this is the second time this particular type's copies have gone stale. Worth closing at the source rather than re-finding later.

Scope

⛔ Two lines, same length, no net growth. The skills line ratchet applies (net additions paid with deletions), and you already scoped the fix correctly: a same-length spelling change plus, at most, a short comment pointing at PluginType. Spelling it type?: PluginType; and dropping the trailing enumeration is itself a net deletion, which is the ideal shape here — the comment was only ever standing in for the type.

⛔ Do not sweep skills/** for other stale type copies in this card. If that is worth doing it is worth measuring first; #14628 is the template for how to file it with a count.

Merge path

skills/** is a governed surface: this lands as a normal PR and is merged by hand by the maintainer (2026-08-08 / 2026-08-11 / 2026-08-18 lineage). ⛔ No agent seat approves it, and it never enters the merge queue. A dispatch constraint this is not — the card is claimable now.

Filing it out of #13925's file surface rather than folding it in was the right call, and for the reason you give: skills/** is governed, and a PR whose diff crosses into a governed surface stops being reviewable under its own ruling.
