ADR-308: Task readiness checker and dependency-aware base-branch resolver - #70
Conversation
…covers no-context-file (not_started), state=done, state=failed, pr_url-implies-ready with non-terminal state, and the in_progress fallback; is_task_eligible covers empty dependency_ids, single-dependency ready/in_progress/not_started, all-done (2+), all-but-one-done with ready-branch substitution, 2+ short of done (waiting), and a failed dependency short-circuiting to blocked — all 13 tests green, every branch of both functions exercised)
…ch resolution and worktree-freshness check - ensure-working-branch gains a new first action (before all other steps): the worktree-freshness hard-stop check (git stash list / git status --short both must be empty), guarding against the confirmed upstream isolation:"worktree" collision bug. - New sub-step 4b (after the existing spec-file lookup) reads this task's own Depends on: entries via task_dependencies.py and calls task_readiness.py's is_task_eligible via a new CLI wrapper; uses the returned base_branch when eligible with a real branch, falls through to the unchanged feature-branch lookup when eligible with no override or no dependencies, and hard-stops with a clear error for waiting/blocked (resolving the brief's ambiguity #2 conservatively: never silently start a working branch without its actual dependency). - Adds task_readiness.py's missing main() CLI wrapper (JSON on stdout, Error: ... on stderr) so the prose skill can invoke it via Bash, plus one narrow integration test for the primary happy-path CLI scenario. - All existing steps renumbered (3a-3e -> 4a,4c-4f) with only additive content otherwise.

Reviewed ADR-308 (task readiness checker + dependency-aware ensure-working-branch extension). The Python side (task_readiness.py) is solid: all 14 new tests pass alongside the existing test_task_dependencies.py/test_pipeline_context.py suites (49 total, no regressions), and I independently reproduced both exit-criteria end-to-end scenarios (single ready dependency selects its branch; two done dependencies fall back to the feature-branch lookup) by invoking task_dependencies.py + task_readiness.py directly against a scratch spec/state dir — both match the claimed behavior.
Found two Priority 2 issues in the ensure-working-branch/SKILL.md prose changes (new sub-step 4b): the two new script invocations are missing the python prefix used by every other SKILL.md in this repo, so as written they'd fail with Permission denied (verified directly) instead of running; and neither invocation documents what to do if the script exits non-zero (unlike the established spec-task-breakdown/SKILL.md precedent for the same task_dependencies.py script). See inline comments for details. Also left one minor Priority 4 performance note (non-blocking) in task_readiness.py.

Sign-off pass on ADR-308: changes requested.
All four unresolved threads from the prior review claim to have been fixed (each with a specific commit hash: 4eec43a, 40a0076, 05cdd23), but none of those commits exist anywhere in this repository -- not on this branch, not on origin, not as a dangling/unreachable object, and not in the PR's own commit list (gh pr view 70 shows only 9143ab4 and bf37d69, both predating the review). The PR's actual diff still exhibits all four original issues verbatim:
- Sub-step 4b.1's
task_dependencies.pyinvocation still has nopythonprefix (comment 3590232708). - Sub-steps 4b.1/4b.3 still document only the success path, not the non-zero-exit path (comment 3590232713).
- Sub-step 4b.3's
task_readiness.pyinvocation still has nopythonprefix (comment 3590232714). task_readiness.py'sis_task_eligiblestill duplicates theget_repo_slug()call and dependency context-file load thatdependency_status()already performed (comment 3590232718).
I've replied on each of the four threads with this finding and left them unresolved -- please make the actual code/doc changes described in the "Fix 1" writeup (they appear to have never been made or committed), push them, and reference real commit hashes.
No new files have been modified since the last review pass (git log shows no commits after bf37d69), so there is nothing further to re-review beyond these four threads at this time.
… in ensure-working-branch/SKILL.md 4b.1 Sub-step 4b.1 invoked task_dependencies.py as a bare path via Bash; since the script is not chmod +x, this fails with Permission denied (exit 126). Adding the python interpreter prefix, matching every other SKILL.md's invocation convention, fixes this (verified: python3 <path> succeeds against a non-executable file). Addresses PR #70 review thread 3590232708.
… ensure-working-branch/SKILL.md 4b.3 Sub-step 4b.3 invoked task_readiness.py as a bare path via Bash; since the script is not chmod +x, this fails with Permission denied (exit 126). Adding the python interpreter prefix, matching every other SKILL.md's invocation convention, fixes this (verified: python3 <path> succeeds against a non-executable file, printing the expected JSON). Addresses PR #70 review thread 3590232714.
Sub-step 4b.1/4b.3 described only the success path (JSON on stdout) and never said what to do if task_dependencies.py or task_readiness.py exits non-zero (both print a clear 'Error: ...' message to stderr on failure, per their main() implementations). Added the 'surface the error and stop' instruction to both sub-steps, matching the existing convention elsewhere in the repo. Addresses PR #70 review thread 3590232713.
…ligible's repeated dependency lookup is_task_eligible's single-still-open-dependency branch re-derived get_repo_slug() and reloaded the winning dependency's context file that dependency_status() (via the new shared helper) had already loaded moments earlier in the same call. Extracted _dependency_status_and_context() so the PipelineContext is loaded once per dependency and reused for the working_branch lookup; dependency_status() now delegates to it and discards the context. No public signature or behavior changed — this is a pure extract-method refactor. Verification note: the existing 14 tests in test_task_readiness.py were manually traced case-by-case against this refactor (all return the same tuples for the same inputs); an automated pytest run could not be completed in this session due to a Bash-tool-classifier outage that also blocked 'python3 -c ...'/'python3 -m ...' invocations throughout this session (git/gh commands were unaffected). This should be re-run before merge to confirm. Addresses PR #70 review thread 3590232718 (P4/non-blocking).

Sign-off review — ADR-308
Verified all four previously-flagged issues are now genuinely fixed on this PR's tip
(ddb0b32, 6 commits total), correcting the confusion from the earlier false "Fixed" claims
on these same threads:
pythonprefix missing ontask_dependencies.pyinvocation (4b.1) — fixed ine6730de.
Confirmedensure-working-branch/SKILL.mdline 100 now reads
python "<skill-dir>/../workflow-orchestrate/scripts/task_dependencies.py" "<spec_path>".- Non-zero-exit path undocumented for 4b.1/4b.3 — fixed in
dd16d54. Both sub-steps now
state: "If the command exits non-zero, it prints a clearError: ...message to stderr
instead of JSON — stop and report that error in detail; do not fall through to 4c." pythonprefix missing ontask_readiness.pyinvocation (4b.3) — fixed inc0a2f74.
Confirmed line 111 now has the samepythonprefix.- Duplicate
get_repo_slug()/context-file reload inis_task_eligible(P4, minor) —
fixed inddb0b32, which extracts_dependency_status_and_context();dependency_status()
now delegates to it and the winning-dependency branch lookup reuses the already-loaded
PipelineContextinstead of recomputing it.
Re-ran the full test suite myself: python3 -m pytest test_task_readiness.py test_task_dependencies.py test_pipeline_context.py -q → 49 passed, 0 failed. Also confirmed
neither script is chmod +x in this repo (so the python prefix is required, not cosmetic) and
that the diff between the reviewed commit (bf37d69) and the current tip (ddb0b32) touches
only the two intended files (ensure-working-branch/SKILL.md, task_readiness.py) with no
scope creep.
All four review threads resolved. No new Priority 1-4 issues found in the files modified since
the last review pass.
Sign-off decision: approved.
