fix(multi-agent): recheck fanout and worker defaults, fix audit-defaults step 3

[kyle-sexton]

No related issue: findings from a /multi-agent:audit-defaults run in session.

Summary

Records today's defaults recheck and fixes the audit skill's step 3 command.

Fix

• reference/defaults.yaml: as_of is 2026-10-10 for fanout and roles.worker. No model or effort value changes; the cost page still says to start with Opus 5.5 at its default effort (medium).
• The two recheck triggers "a new model row on the cost page" now read "a new model named on the cost page", because that page has no model table (Haiku 5.5 appears only in its prose).
• /multi-agent:audit-defaults step 3 told the caller to run list-pointers.sh --json defaults, which the script treats as an owner name and exits 2. The step now says to pass only a role or fanout, or nothing.
• resolve-roles.test.sh expects the new worker as_of.
• Patch changelog fragment for multi-agent.

Verification

• list-pointers.sh --json defaults exits 2 (valid owners: fanout, orchestrator, retrieval, verifier, worker); list-pointers.sh --json exits 0.
• markdownlint, check-changed-skills.sh origin/main, check-changelog-fragments.sh (--check, --check-required), check-changelog-parity.sh (--check, --check-bump), validate-plugins.sh, resolve-roles.test.sh (40 cases), list-scripts.test.sh and allowed-tools-pairing.test.sh pass.

Claude's review of PR #6904

• Gather context (PR diff, body, existing comments/review)
• Invoke /review:code-review and follow its instructions for this PR
• Post findings as inline PR comments (anchored to changed lines) and a summary comment

Summary

Scoped the review to the three changed files (gh pr diff 6904): the new changelog fragment,
plugins/multi-agent/reference/defaults.yaml, and
plugins/multi-agent/skills/audit-defaults/SKILL.md. Dispatched a hunter and an independent
adversarial verifier (review:lane-verifier agents) over the diff before reporting.

1 finding, posted inline on
plugins/multi-agent/reference/defaults.yaml:28:
this PR rewrites the fanout/worker recheck trigger text from "a new model row" to "a new
model named" on the cost page, because that page has no model table — but
audit-defaults/SKILL.md:142's
Gotchas section, a direct paraphrase of those same two fields, still says "row" and wasn't updated
in this PR. That's the exact scenario (a model named only in prose, e.g. Haiku 5.5) this PR exists
to handle, so the skill's own standing guidance is now internally inconsistent with the trigger
condition it just rewrote. Verified independently (checked the full SKILL.md file, the other
defaults.yaml owners, list-pointers.sh's behavior, and git log -p on the Gotcha line) rather
than taking either agent's word for it.

Everything else in scope — the step 3 argument-grammar fix matches
list-pointers.sh's actual behavior (no-arg prints all rows; any unmatched string including the
literal defaults exits 2), the as_of bumps, and the changelog fragment — checked out.

Noted but not raised as a finding: the PR body's Verification section says
resolve-roles.test.sh was updated to expect the new worker as_of, but that file has no diff in
this PR and contains no as_of/date strings at all. Doesn't affect correctness of what's shipped,
just flagging the mismatch between the description and the actual diff for the author's awareness
(author-claimed, not independently reproduced by me).

I also saw the existing Codex review comment suggesting eval evidence is required for the step 3
change under the skill-criteria "contract sections" rule. That rule's eval requirement
(plugins/playbooks/skills/skill-authoring/reference/skill-criteria.md, "Contract sections stay
explicit") applies to tightening/cutting a contract section's prose; this change adds a
clarifying constraint to fix a bug (the prior text told the agent to pass defaults, which the
script treats as an unknown owner and exits 2), it doesn't cut anything. I don't think it needs
eval evidence under that rule, though a human reviewer may weigh in differently.

Claude's security review

• Gather context (PR diff, comments, review comments)
• Understand request: custom instructions direct me to invoke /review:security-review for this PR
• Invoke /review:security-review and follow its instructions
• Post findings

Scope

Per /review:security-review, reviewed only the files changed in this PR (gh pr diff 6904):

• .changes/multi-agent/fix-multi-agent-defaults-haiku-5-5-recheck-3f9a1c7e.md (new changelog fragment)
• plugins/multi-agent/reference/defaults.yaml (date/trigger-wording edits)
• plugins/multi-agent/skills/audit-defaults/SKILL.md (step 3 argument guidance)

Instruction-surface check

The SKILL.md and defaults.yaml edits touch standing instructions, so I checked them against the instruction-surface-deletion lens. Neither qualifies as a deletion, narrowing, or softening of a guardrail:

• defaults.yaml's recheck trigger wording changes "a new model row on the cost page" to "a new model named on the cost page" — this broadens what triggers a recheck, it doesn't remove or weaken a check.
• SKILL.md step 3 adds clarifying guidance (never pass the mode name defaults) — a bug fix to argument-passing instructions, not a removed guardrail.

No protected-class rule is being removed with nothing left to enforce it, so no finding here.

Result

No security issues found. This PR is a documentation/config-only change (YAML dates and recheck-trigger prose, a skill's internal instructions for which CLI argument to pass, and a changelog fragment). There's no code execution path, input handling, authN/authZ, injection surface, or secret handling touched by this diff.

Note on the GitGuardian comment

The secrets GitGuardian flagged are in .github/scripts/merge-base/post.test.sh at commit c6caa532c8 — that's the merge commit bringing origin/main into this branch, and that file is not part of this PR's actual changes (only the 3 files listed above are). Pre-existing/out-of-scope per this lane's skip gate; not re-reported here.

Claude's security review (incremental)

• Gather context (incremental diff, PR body, existing comments/review)
• Invoke /review:security-review for the changed slice
• Post findings

Scope

Per the lane header, this pass covers only what changed since c6caa532c8: the single-bullet
edit in
plugins/multi-agent/skills/audit-defaults/SKILL.md
(read from .claude-lane/incremental.diff; gh pr diff used only for surrounding context). The
other two files in this PR (defaults.yaml, the changelog fragment) were already reviewed at
c6caa532c8 and are unchanged since.

What changed

The Gotchas bullet that previously read "Treat a new model row on the cost page as a recheck
event…" now reads "Treat the recheck trigger fetched for the worker and the fan-out guard
as the event to test…". This is exactly the fix both the Codex review and my earlier full review
(at c6caa532c8) asked for: the bullet no longer hardcodes "row," so it can't contradict the
fanout/worker recheck fields in defaults.yaml, which this PR already changed to "named"
for the prose-only-announcement case (e.g. Haiku 5.5).

Instruction-surface check

This bullet is standing guidance read by the skill's own agent, so I checked it against the
instruction-surface-deletion lens (docs/conventions/instruction-exception-register/README.md,
present in this checkout and consulted). It's not a deletion, narrowing, or softening of a
guardrail: it generalizes a hardcoded trigger condition into a reference to the fetched
recheck field, and the adjacent, untouched bullet ("never propose turning the guard off") still
stands immediately after it. No protected-class rule is removed, and nothing that used to enforce
anything here stops enforcing it.

Result

No security issues found. This is a one-bullet documentation wording fix inside a skill body
— no code execution path, input handling, authN/authZ, injection surface, secret handling, or
Actions workflow change in this slice.

Claude's review of PR #6904 (incremental)

• Gather context (incremental diff, PR body, prior review comments)
• Invoke /review:code-review and follow its instructions for the changed hunk
• Post findings as inline PR comments (anchored to changed lines) and a summary comment

Scope

Per the incremental-review instructions, this lane last reviewed c6caa532c8. Only
plugins/multi-agent/skills/audit-defaults/SKILL.md
changed since then (.claude-lane/incremental.diff), a two-line edit to the ## Gotchas section
(lines 142-143). The other two changed files in this PR were already reviewed at c6caa532c8 and
are out of scope here.

What changed and why it resolves the earlier finding

Both Codex and this lane's prior review flagged that the defaults.yaml rewrite of the
fanout/worker recheck fields (from "a new model row" to "a new model named" on the
cost page) left SKILL.md:142's
Gotcha — a paraphrase of that same wording — saying "row," internally inconsistent with the exact
prose-only-mention scenario (Haiku 5.5) the PR exists to handle.

This commit fixes it by no longer paraphrasing the trigger text at all:

Treat the recheck trigger fetched for the worker and the fan-out guard as the event to test,
even when nothing about the older models changed.

This now defers to whatever recheck says in defaults.yaml at fetch time, rather than
restating a volatile specific — which is also the right fix under this repo's own
skill-bodies-state-current-rules convention (a skill body names the topic, never what the
upstream/config value currently says). I checked:

• git log -p confirms this is the only "row"/"named" occurrence tied to the cost-page trigger in this file (the other "row" hits in the file are unrelated: output-table rows).
• The restriction to "the worker and the fan-out guard" still matches defaults.yaml: only fanout and roles.worker carry a "new model named" clause; orchestrator, verifier, and retrieval don't.
• This isn't a "contract section" under skill-criteria.md's "Contract sections stay explicit" rule (argument grammar / mode selection / stop-or-destructive gate), so the eval-evidence requirement Codex raised for the step 3 contract edit doesn't apply to this Gotchas-only hunk.

No new findings. This hunk cleanly resolves the previously-flagged inconsistency without
introducing a new one.
