Not sure we want this at all (this is a retor-agent suggested change that should've been discussed IMO) - not having certain labels is a way for repo owners to avoid having fullsend set the labels on the repos, though perhaps we should have mandatory and optional labels, where the mandatory ones are the ones used to hand-off work between agents and may be auto-created

Review Squad — 3 agents (Claude x2, Grok), MEDIUM+ findings
Posting only findings that are new — deduped against the 8 existing comment threads and the 3 prior bot review rounds. Every finding below was verified against the code at 9f8c520 before posting; agent-reported findings that turned out to be false positives, already-resolved, or already-declared-intentional were dropped.
6 inline comments posted: 1 critical, 2 high, 3 medium.
The headline is the critical one on scripts/post-triage.sh:24: the source of scripts/lib/labels.lib.sh from a non-bundled runtime script violates the invariant this repo documents in its own README.md:55, and will abort triage on every enrolled repo. CI cannot catch it — check-bundle skips non-BUNDLE_SRCS scripts and shellcheck runs with -e SC1091. That finding and the post-triage.sh:81 one together mean the open CHANGES_REQUESTED is still unresolved: the code does not implement the mandatory/optional split described in the reply to it.
Two additional medium items without a clean inline anchor
[medium] premature-decision — the hardcoded colours contradict the live label set. Scoped to colours only; the description-prefix half of this is already settled as intentional and I'm not reopening it. Against gh api repos/fullsend-ai/agents/labels:
| label | live on this repo | _label_defaults |
|---|---|---|
ready-for-review |
a81af5 |
0E8A16 |
ready-to-code |
ededed |
0e8a16 |
blocked / feature / needs-info / triaged |
all ededed |
e11d48 / a2eeef / d876e3 / c2e0c6 |
No issue, PR comment, or reviewer specified these values — they were chosen, not derived, and nothing pins them. Newly provisioned repos will also get mixed casing for the same green (0e8a16 vs 0E8A16 for the identical colour). Suggest deriving from the existing inline call sites, which are the de-facto spec, or recording where each value came from.
[medium] premature-decision — the token-permission answer cites the wrong token. Issue #479 step 3 asks to verify the coder-role token has Issues write for gh label create. The reply cited PUSH_TOKEN / the workflow permissions: block, but those govern the default GITHUB_TOKEN; the post-script actually receives steps.app-token.outputs.token, minted by .github/actions/mint-token with role: coder, whose permission set lives in the App configuration and cannot be granted or documented by a permissions: block. Probably fine in practice — POST /repos/{o}/{r}/labels and POST .../issues/{n}/labels share the same fine-grained Issues permission, and --add-label already works — but it was reported as verified when it wasn't, and ensure_label degrades a 403 to a warning, so if the coder role is read-only for label creation the symptom is the same silent non-dispatch #479 set out to fix.
Not re-flagged (settled in prior rounds)
scope-exceeded on post-triage.sh; preemptive ensure_label vs 404/422 gating; the 17-label count; the exit-code doc comment; SCRIPT_DIR_TRIAGE naming; the "Fullsend:" description prefix; the swallowed gh label create stderr (resolved in 50c786e).
Where a new finding lands near a settled thread, the inline comment says explicitly how it differs.
Verified as correct (no action)
local err on its own line followed by if ! err=$(...) correctly preserves exit status — no local-masking bug. if defaults=$(_label_defaults ...) is set -e-safe as an if condition. The include guard [[ -n "${LABELS_LIB_SH_LOADED:-}" ]] && return 0 is safe at top level of the bundle when the variable is unset (reproduced). The literal tabs in the %%/## splits are genuinely present and survive bundling intact. create_args is a proper array expanded as "${create_args[@]}", so repo and label names carry no injection risk. make check-bundle passes and post-code.sh is byte-exact.

[critical] runtime-source-unavailable
post-triage.sh is a hand-maintained runtime script — it is not in BUNDLE_SRCS (Makefile:4 lists only pre-code, post-code, post-fix, post-prioritize). It now sources a file from scripts/lib/, which does not travel with it at runtime. This aborts triage on every enrolled repo, before the triage result is read, before any label, before the triage comment.
Four independent confirmations:
- This repo's own README documents the invariant.
README.md:55— "Harness fetches each runner script as an isolated blob, so post-scripts cannotsourcefiles fromscripts/lib/at runtime." AndREADME.md:63— "A custom post-script that tries tosourcea base lib at runtime will fail because the harness only fetches the single script blob." - The resolver fetches exactly one file.
fullsend/internal/harness/compose.go:881fetchBaseFilefetches<baseURLDir> + <relPath>and caches it content-addressed at<workspace>/.fullsend-cache/<sha256>/content. At exec timedirname "${BASH_SOURCE[0]}"is that hash directory — there is nolib/sibling. Sibling files are never fetched. - The scaffold ships no
lib/.internal/scaffold/fullsend-repo/scripts/contains 12 files and nolibentry. - Reproduced. Copying only
post-triage.shinto an empty directory and running it:Underline 24: /private/tmp/blobsim/lib/labels.lib.sh: No such file or directory EXIT=1set -euo pipefailthe script dies here.
Why CI is green: make check-bundle only covers BUNDLE_SRCS, so post-triage is skipped; post-triage-test.sh:10 sets POST_SCRIPT="${SCRIPT_DIR}/post-triage.sh" so tests always run with lib/ as a sibling; and shellcheck runs with -e SC1091, suppressing the unresolvable source. All three suites pass on this branch.
Suggested fix: Revert the post-triage.sh changes and confine ensure_label to the bundled post-code path — labels.lib.sh + post-code.src.sh already work correctly because they go through the bundler. The alternative (rename to post-triage.src.sh, add to BUNDLE_SRCS, make script-build, commit the generated post-triage.sh, update post-triage-test.sh to honour SCRIPT_TEST_TARGET) is the real fix but is a much larger change than #479 authorizes.
Independently, add a regression guard in scripts/bundle-sh-test.sh: assert that no scripts/*.sh lacking a matching .src.sh contains a source .*lib/.*\.lib\.sh line.
Distinct from the settled inconsistent-variable-naming thread on this line — that was about the SCRIPT_DIR_TRIAGE name, this is about the source on the next line failing at runtime.

[high] mandatory-optional-split-not-implemented
Placing ensure_label at the top of add_label() auto-creates every label the action handlers apply, bypassing the label_exists guard entirely. That guard is pre-existing and only covers the label_actions loop (agent-suggested labels) at line ~505.
Labels now auto-created via direct add_label calls: needs-info (:131), duplicate (:146), blocked (:267), pr-open (:314), triaged (:403/432/436), bug (:409), documentation (:417), feature (:431), question (:449), not-planned (:460), ready-to-code (:539). Eleven labels — only one of which (ready-to-code) is in the declared mandatory set.
Driving the script under its own test mock confirms it:
action=question -> gh label create question --description Fullsend: issue is a question
action=not-planned -> gh label create not-planned --description Fullsend: will not be implemented
action=insufficient -> gh label create needs-info --description Fullsend: issue needs more information
action=sufficient/bug -> gh label create bug --description Fullsend: bug report
gh label create ready-to-code --description Fullsend: triggers code agent dispatch
question is the exact label cited in the PR discussion as an example of an optional label that should "fail silently if missing". It is auto-created.
The concrete consequence is the one raised in the open CHANGES_REQUESTED: ready-to-code is a dispatch trigger (labels.lib.sh:17 — "triggers code agent dispatch"). A repo owner who deleted ready-to-code to stop fullsend auto-dispatching the code agent will have it silently recreated and applied on the next triage run at line 539. Absent-label-as-opt-out is bypassed for all eleven.
Separately, ready-for-triage — one of the three labels designated mandatory — never reaches ensure_label at all; post-retro.sh:146 still creates it inline with --force.
Suggested fix: Make the split explicit in the library rather than implicit in add_label:
# Only these labels are auto-created; everything else must pre-exist.
_MANDATORY_LABELS="ready-for-review ready-to-code ready-for-triage"
ensure_label() {
local repo="$1" label="$2"
case " ${_MANDATORY_LABELS} " in *" ${label} "*) ;; *) return 0 ;; esac
...
}Then call ensure_label only from the sites that need it rather than from generic add_label, and add a post-triage-test.sh case asserting add_label "question" emits no gh label create.
Distinct from the settled scope-exceeded thread on this line — that was about whether these changes are authorized, this is about whether they do what the PR says they do.

[high] unreachable-assignment-and-silent-failure
exit 1 sits directly above maybe_assign_pr "${PR_NUMBER_FROM_URL}" (line 718), making it unreachable on this path. Previously the || gha_echo warning fallback let execution continue, so a PR whose label application failed still got assigned to a human via the invoker → issue assignee → issue author chain.
After this change, a label failure leaves a pushed branch and an open PR with no ready-for-review label and no assignee — strictly less discoverable than before. Issue #479's motivating incident is a PR sitting unreviewed for 24 days, so this inverts the intent of the fix on exactly the path it was meant to harden.
Second problem: exit 1 does not fire the trap 'report_post_failure_to_issue' ERR installed at line 61. Verified:
$ bash -c 'set -euo pipefail; trap "echo ERR-TRAP-FIRED" ERR; if x=$(false 2>&1); then echo ok; else exit 1; fi'; echo "rc=$?"
rc=1 # no ERR-TRAP-FIRED
Every other fatal path in this file routes through post_fail_to_issue <category> <detail> (15 call sites: :117, :131, :301, :312, :326, :444, :520, :694, ...), which posts a categorized comment on the source issue. This new path posts nothing — the only trace is an ::error:: annotation on a red job. Wiring the ERR trap would not help either: post-failure-report.lib.sh:287 defaults the detail to "Post-code script failed before push or PR creation completed", which is factually wrong here since both the push and the PR succeeded.
Suggested fix: Move the assignment above the label block (it does not depend on the label), and route the failure through the existing machinery:
PR_NUMBER_FROM_URL="${PR_URL##*/}"
maybe_assign_pr "${PR_NUMBER_FROM_URL}"
ensure_label "${REPO_FULL_NAME}" "ready-for-review"
if label_err=$(gh issue edit "${PR_NUMBER_FROM_URL}" --repo "${REPO_FULL_NAME}" \
--add-label "ready-for-review" 2>&1); then
echo "Applied ready-for-review label to PR #${PR_NUMBER_FROM_URL}"
else
post_fail_to_issue label-apply-failed \
"Failed to apply ready-for-review to PR #${PR_NUMBER_FROM_URL} — review agent will NOT be dispatched: ${label_err}"
fiDistinct from the settled exit-code-contract-violation thread nearby — that was about updating the exit-code doc comment (addressed in 9f8c520), this is about the assignment being skipped and no issue-side signal being emitted.

[medium] no-behavioral-test-coverage
Both new assertions are text greps — grep -q 'ensure_label.*ready-for-review' and grep -q '_label_defaults' && grep -q 'ensure_label'. They assert that certain strings appear in a file. Neither ever executes ensure_label.
They would still pass if _label_defaults returned the wrong colour, if the tab-split produced a description containing the colour, if the *already exists* arm were inverted, or if ensure_label unconditionally exit 1'd. The second assertion is also partly redundant with make check-bundle, which already guarantees the lib is inlined.
This matters because the behaviour change in post-triage.sh's add_label() ships with zero coverage: post-triage-test.sh's mock gh (lines 21-43) always exits 0, so the already exists arm, the Warning: arm, and the new exit 1 branch are unexercised anywhere in the suite. And run_test only grep -qFs a single expected pattern, so the newly-emitted gh label create <control-label> line in ~90 other triage tests is entirely unasserted.
The repo has clear precedent for direct library unit tests — scripts/pr-assignee-test.sh, scripts/gitleaks-install-test.sh, and scripts/post-failure-report-test.sh each source their lib and are wired into make script-test. labels.lib.sh is the only lib in scripts/lib/ with no corresponding *-test.sh.
Suggested fix: Add scripts/labels-test.sh that sources the lib with a stub gh on PATH, and register it in the Makefile script-test list next to pr-assignee-test.sh. Minimum cases:
- known label emits
--description/--colorwith exactly the expected values - unknown label emits neither
- stub
ghexiting 1 withlabel with name "x" already exists...produces no stderr and returns 0 - stub
ghexiting 1 withHTTP 403: Resource not accessible by integrationproduces aWarning:and still returns 0 - (once the mandatory gate exists)
ensure_label repo questionemits noghcall
Also note BUNDLED_SCRIPT is hardcoded to post-code.sh on line 1394, so under SCRIPT_TEST_TARGET=bundled — CI's second pass — that assertion tests the same file twice rather than the source.

[medium] premature-decision
The duplicate-detection contract is a match on gh's human-readable error prose. I verified the assumption holds today rather than assuming it — cli/cli pkg/cmd/label/create.go (v2.96.0):
func isLabelAlreadyExistsError(err api.HTTPError) bool {
return err.StatusCode == 422 && len(err.Errors) == 1 &&
err.Errors[0].Field == "name" && err.Errors[0].Code == "already_exists"
}
...
if errors.Is(err, errLabelAlreadyExists) {
return fmt.Errorf("label with name %q already exists; use `--force` to update its color and description", opts.Name)
}So on a duplicate, gh exits non-zero and prints a message containing already exists — this glob currently matches, and the comment on line 39 is correct. This is not a live bug.
Two things are unverified, though:
- The fallback. The mapping is only applied when the 422 body has exactly one error item with
field == "name"andcode == "already_exists". Any other shape falls through to go-gh's genericHTTPError.Error(), which rendersHTTP 422: Validation Failed (https://api.github.com/repos/o/r/labels)— noalready existssubstring. In that case a benign duplicate is reclassified as a real failure and printsWarning: gh label create ... failedon every run, in every customer repo. That is exactly the log-noise-that-reviewers-learn-to-ignore failure mode Port fullsend PR 5657 (ready-for-review label create-on-missing) to the live post-code.sh in this repo #479 is trying to reduce. - Durability. The contract is an English substring in a
fmt.Errorfstring with no stability guarantee, and there is no test, no minimum-gh-version assertion, and no comment recording which version was checked.
Suggested fix: Either stop parsing prose and use a documented status-code contract —
gh api "repos/${repo}/labels/${label}" --silent >/dev/null 2>&1 || gh label create ...— or at minimum match the machine-readable forms too (*already\ exists*|*already_exists*|*HTTP\ 422*), record the verification in the comment (# Verified against gh 2.96.0: ...), and cover it in the new scripts/labels-test.sh so a wording drift surfaces as a test failure rather than as production log noise.
This is about how the create result is classified. It is distinct from the settled API-contract-mismatch thread (which was about when to create — preemptive vs. gating on 404/422) and from the error-handling-gap finding resolved in 50c786e (which was about the failure being swallowed entirely; this concerns the classification logic that fix introduced).

[medium] premature-decision — incomplete migration leaves two --force writers that clobber these values
The PR summary lists "No --force: gh label create is called without --force, preserving existing label metadata" as one of three headline fixes, and the inline --force create for pr-open was removed from post-triage.sh. But pre-code.sh — which runs on every code-agent dispatch — still does:
# scripts/pre-code.src.sh:112-114 (bundled: scripts/pre-code.sh:139-141)
gh label create "pr-open" --repo "${REPO_FULL_NAME}" \
--description "An open PR already addresses this issue" --color "D4C5F9" \
--force 2>/dev/null || trueSo the admin-customisation clobber this PR claims to have fixed is still live for pr-open on the highest-frequency path, and the two writers now disagree on the string: triage creates "Fullsend: open PR addresses this issue", pre-code force-rewrites it to "An open PR already addresses this issue". The description now oscillates depending on which agent ran last — a regression relative to the pre-PR state, where post-triage and pre-code used identical text.
The same flip applies to ready-for-triage via post-retro.sh:146, which also uses --force. That label is one of the three designated mandatory and is not wired to this library at all.
Six inline gh label create sites remain unmigrated:
| Site | Label | --force? |
|---|---|---|
pre-code.src.sh:112 |
pr-open |
yes |
post-retro.sh:146 |
ready-for-triage |
yes |
post-fix.src.sh:442 |
needs-human |
no |

ready-for-merge |
no |
post-review.sh:425 |
requires-manual-review |
no |
post-review.sh:432 |
rejected |
no |
Note that post-review.sh, post-retro.sh, and post-fix.sh are non-bundled runtime scripts, so per the critical finding on post-triage.sh:24 they cannot migrate to this lib without being converted to .src.sh + BUNDLE_SRCS first — the "migrate incrementally" path does not currently exist.
Suggested fix: Drop --force from pre-code.src.sh:114 and re-run make script-build (a two-line change to an already-bundled script that actually delivers the stated fix), and align the pr-open description between the two writers. If touching pre-code is out of scope, remove the "No --force" bullet from the PR body and open a follow-up, so the claim isn't recorded as delivered.
