Ships the canonical label set and the classifier that labels newly-filed issues.

Additive only — never removes a label, never overrides a human's classification, silent when unsure, never fails an issue.

Also adds this repo's two new workflows to .github/workflows/actions.lock as []. That lock is keyed by workflow path and refuses any workflow it does not list — a startup_failure, which produces no check run and is therefore silent. gh actions-lock cannot add these: it records action versions, and both workflows deliberately use none.

See docs/LABELS.adoc in hyperpolymath/.git-private-farm.

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Added automated issue labelling based on titles, tags and keywords.
    • Added workflows to apply suitable labels to new or reopened issues.
    • Added synchronisation of the repository’s standard label set, including scheduled updates.
    • Added a defined taxonomy covering issue type, area, priority, status, metadata and scope.

Walkthrough

Adds a canonical GitHub label taxonomy, a jq classifier for issue titles, a label synchronisation workflow, and an issue triage workflow. Automation preserves frozen and existing labels while applying defined classifications.

Changes

Issue label automation

Layer / File(s) Summary
Label taxonomy and classifier rules
.github/labels.json, .github/label-classifier.json
Defines 37 labels, six tiers, frozen labels, title and bracket mappings, keyword signals, tier limits, and precedence rules.
Issue title classification
.github/scripts/classify-issue.jq
Normalises titles, parses prefixes and tags, matches keywords, enforces tier limits, and emits canonical labels only when classification conditions are met.
Canonical label synchronisation
.github/workflows/labels.yml
Creates missing labels and updates non-frozen label metadata on dispatch, label-file changes, and a monthly schedule.
Automated issue triage
.github/workflows/label-triage.yml
Classifies newly opened or reopened issues, preserves existing labels, filters results against repository labels, and applies labels safely.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to f8276

This PR can update repository-wide labels from pushes to any branch, while malformed configuration or API failures may be treated as successful no-ops and special characters in descriptions may be corrupted. These are bounded but concrete merge-readiness risks, so the trigger and failure-handling issues should be addressed before merging.

Pull Request Overview

The PR implements an automated label management system that adheres to technical constraints (no Python, additive-only), yet lacks any automated verification for the underlying classification logic. While the solution passes Codacy quality standards, several implementation risks were identified in the Bash and jq scripts.

Critically, the 'Never fails' requirement is implemented via blanket error suppression to /dev/null, which will mask API failures and permission issues. Furthermore, the label synchronization and triage workflows contain logic that is vulnerable to shell word splitting and malformed input (e.g., label descriptions with newlines). Before merging, it is highly recommended to implement a test suite for the .github/scripts/classify-issue.jq logic and address the identified shell-scripting vulnerabilities.

About this PR

  • The system lacks automated tests to verify the classification rules against a corpus of titles/tags. Given the complexity of the jq regex and precedence logic, this poses a high risk of regression.
  • Piping errors to /dev/null and using '|| true' ensures the workflow doesn't fail the issue, but it leads to silent failures. Consider logging errors to the workflow summary even if the step exit code is suppressed.

Test suggestions

  • Classify issue title with conventional commit prefix (e.g., 'feat: some feature' -> 'enhancement')
  • Classify issue title with bracketed tag (e.g., '[proofs] validation' -> 'proofs')
  • Classify issue via keyword matching (e.g., 'broken' -> 'bug')
  • Verify that auto-triage does not add a 'type' label if one is already present (no override)
  • Label sync: create missing labels defined in labels.json
  • Label sync: update colors/descriptions for existing non-frozen labels
  • Label sync: ensure labels in the 'frozen' list are never updated or renamed
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classify issue title with conventional commit prefix (e.g., 'feat: some feature' -> 'enhancement')
2. Classify issue title with bracketed tag (e.g., '[proofs] validation' -> 'proofs')
3. Classify issue via keyword matching (e.g., 'broken' -> 'bug')
4. Verify that auto-triage does not add a 'type' label if one is already present (no override)
5. Label sync: create missing labels defined in labels.json
6. Label sync: update colors/descriptions for existing non-frozen labels
7. Label sync: ensure labels in the 'frozen' list are never updated or renamed
Low confidence findings
  • Fetching scripts via 'gh api' and 'base64 -d' introduces a runtime dependency on GITHUB_SHA and API availability for every execution, which may lead to intermittent failures if the API is rate-limited.

🟡 MEDIUM RISK

Applying labels via unquoted command substitution will break for any label name containing spaces (e.g., 'good first issue') due to shell word splitting. Use Bash array parameter expansion to correctly pass each label as a distinct argument.

🟡 MEDIUM RISK

Suggestion: The TSV-based parsing logic for labels is vulnerable to descriptions containing newlines. If a label description is multi-line, the while read loop will fail to correctly identify label names and properties in subsequent iterations. Refactor the sync job to iterate over label data as JSON objects using jq -c instead of @tsv to handle multi-line descriptions safely.

Ships the canonical label set and the classifier that labels newly-filed
issues. Additive only: it never removes a label, never overrides a human's
classification, stays silent when unsure, and never fails an issue.

Also adds this repo's two new workflows to .github/workflows/actions.lock as
'[]'. That lock is keyed by workflow path and refuses any workflow it does not
list -- a startup_failure, which produces no check run and is therefore silent.
`gh actions-lock` cannot add these: it records action versions, and both
workflows deliberately use no actions.

Do not report API failures as a missing payload.

Lines 59-62 discard stderr and mask the exit status with || true. A token scope problem, a rate limit or a network fault produces the same empty file as a repository without the classifier. The job then prints "no classifier payload in this repo" and exits 0. That is the silent no-op shape which .github/workflows/labels.yml documents at Lines 27-33. Capture the error and print it.

Validate the payload is well-formed JSON before parsing it.

The script never checks that $PAYLOAD is valid JSON before running jq -r '.frozen[]' and jq -r '.labels[] | ... | @TSV' on it. Because set -uo pipefail omits -e, a malformed .github/labels.json (a truncated edit, a bad merge, a syntax typo) makes both jq calls fail silently. The while loop then processes zero lines, created=0 updated=0 skipped=0 failed=0, and the script exits 0. This reproduces the exact "silent, estate-wide no-op" signature that the GH_REPO comment further down (Lines 39-45) explicitly says must never happen, only triggered by a different root cause (a broken payload instead of a missing GH_REPO).

Add an explicit JSON validity check right after the payload is written.

TSV round-trip does not unescape fields; backslash/control characters in descriptions get corrupted.

A past review flagged this TSV parsing as unsafe for multi-line descriptions. That specific claim does not hold: jq's @tsv format escapes line-feed, carriage-return, tab, and backslash into the two-character sequences \n, \r, \t, \\, so a raw newline never actually reaches the while read loop and does not misalign fields.

There is a related, narrower issue the escaping does introduce: the script never unescapes the fields after read. If a label description in .github/labels.json contains a real backslash, tab, carriage return, or newline, gh label create/gh label edit receives the literal escaped sequence (for example, \n as two characters) instead of the real character, so the description applied on GitHub is corrupted. Worse, the drift check on Line 85 compares the same escaped representation on both sides ($cdesc from the existing-labels TSV and $desc from the payload TSV), so this corruption is never detected or re-synced afterwards.

Switching to jq -c per-record JSON output (as the earlier review suggested) and extracting fields with jq -r inside the loop removes this class of escaping problem entirely, rather than only mitigating the multi-line case.

In @.github/workflows/labels.yml around lines 58 - 94, Replace the TSV-based
label iteration and existing-label parsing around the label synchronization loop
with compact JSON records, extracting each field using jq -r so backslashes,
tabs, carriage returns, and newlines retain their original values. Update the
name, color, and description comparisons and gh label create/edit arguments to
use these decoded fields, while preserving frozen-label handling and existing
synchronization behavior.
