Two problems found by deploying the previous commits to production.
FIRST: the rewrite guard compared raw Markdown, so it refused a publish over
formatting. The authoring UI re-serialises a definition when somebody saves it
— writing `webSearch: false` where the hand-authored file omitted the key, and
ordering the frontmatter its own way — and the parser reads absent and false
identically (agent.go: `data["webSearch"] == true`). A definition nobody
meaningfully changed stopped a deploy. Refusing a change that is not a change
is still a bug, even though it fails safe.
definition.SameAgent and SameSkill compare the parsed definition instead, and
are deliberately conservative, because the two ways of being wrong are not
equally bad. A false difference blocks a deploy: visible, recoverable. A false
SAMENESS lets a changed agent overwrite an approved version silently, which is
the thing versioning exists to prevent. So:
- The body is compared verbatim. Agent.Body carries `json:"-"`, so a
comparison that only marshalled the struct would call a completely
rewritten system prompt "unchanged". There is a test that fails loudly on
exactly that, because it is the mistake this design invites.
- List ORDER stays significant. loader.go resolves Skills in order and that
order reaches prompt assembly, so two definitions listing the same skills
differently are still different. A deploy that only reorders still has to
raise its version. That is a limit, recorded in a test rather than left to
be discovered: loosening it needs somebody to decide skill order cannot
matter, which is not a decision to bury in a comparison function.
What it absorbs is exactly what the round trip produces: frontmatter key order,
whitespace, and a defaulted value written out in full.
SECOND: importagents reported "9 agent version(s) recorded" on a run that
recorded nothing. The counter incremented on every successful Snapshot call,
and Snapshot returns nil for the idempotent no-op as well as for a real insert.
The skill counter was already honest; the agent one was not. snapshotAgent now
distinguishes recorded / conflict / already-present, and only the first counts.
Verified locally: 1 on the run that added activity-agent v2, 0 on the re-run,
where it previously said 9. A number that says nine every time is one nobody
checks on the day it matters.
Full suite green against PostgreSQL, only TestLive* skipped.
