VCS Operations Reference

VCS Auto-Detection

Detect which VCS platform the current repo uses and select the right CLI:

# Check git remote
REMOTE_URL=$(git remote get-url origin 2>/dev/null)
if echo "$REMOTE_URL" | grep -q "github.com"; then
  VCS=github    # use `gh`
else
  VCS=gitlab    # use `glab`
fi

Session Config overrides:

• vcs: github|gitlab — force a specific platform
• gitlab-host: <host> — override auto-detected GitLab host (glab reads host from git remote by default)

How Other Skills Reference This

Directive: Consuming skills MUST NOT duplicate VCS auto-detection logic or CLI command syntax inline. This skill is the single source of truth for all VCS operations.

When a skill needs VCS operations, include this reference block in its instructions:

VCS Reference: Detect the VCS platform per the "VCS Auto-Detection" section of the gitlab-ops skill. Use CLI commands per the "Common CLI Commands" section. For cross-project queries, see "Dynamic Project Resolution."

Canonical commands: All glab and gh command syntax — flags, output formats, pagination options — is defined in the "Common CLI Commands" section below. Consuming skills must reference that section rather than redefining commands. If a skill needs a command variant not listed there, add it to this file first, then reference it.

What consuming skills should include:

• The reference block above (copy-paste it verbatim)
• Any skill-specific parameters they pass to commands (e.g., label names, issue templates)
• They should NOT include raw glab/gh invocations or detection snippets

Dynamic Project Resolution

Never hardcode project IDs. Resolve them at runtime — and re-resolve live each session; never cache a project ID across sessions (a stale ID silently targets the wrong project on rename/fork/mirror-drift, and is the root cause behind the close-verification incident documented below).

Current project

# GitLab — get numeric project ID
glab repo view --output json | python3 -c "import json,sys; print(json.load(sys.stdin)['id'])"

# GitHub — get owner/name identifier
gh repo view --json nameWithOwner -q '.nameWithOwner'

Cross-project queries

When a skill needs to reference other projects (e.g., from cross-repos in Session Config):

# GitLab — resolve project ID by name
glab api "projects?search=<project-name>" | python3 -c "import json,sys; [print(p['id'], p['path_with_namespace']) for p in json.load(sys.stdin)]"

# GitHub — resolve repo details
gh api "repos/<owner>/<name>" --jq '.full_name'

Note: Some API calls require numeric project IDs (GitLab) or owner/repo slugs (GitHub). Always resolve dynamically from the project name.

Canonical enumeration pattern

To enumerate ALL projects (or issues) in a group, a single page is never the whole result — paginate and guard against silent truncation:

# GitLab — paginate a group's projects, following x-next-page until empty
page=1
while [ -n "$page" ]; do
  resp=$(glab api "groups/<group-id>/projects?include_subgroups=true&per_page=100&page=$page" --include)
  # parse the response body ($resp) for project ids/paths here, deduping by id.
  # Then advance by reading the `x-next-page` response header — an empty value
  # means this was the last page, so the loop exits (the guard above is what breaks).
  page=$(printf '%s\n' "$resp" | awk -F': *' 'tolower($1)=="x-next-page"{sub(/\r/,"",$2); print $2}')
done

• Follow pagination via the x-next-page response header — loop until it comes back empty. A single-page read on a known-large group is a signal the loop stopped early, not proof the group is small.
• Dedupe by project id — subgroup traversal can surface the same project more than once.
• Silent-zero guard: membership=true can return a misleadingly small subset (e.g. a host that only sees a handful of a group's dozens of projects). If the count looks suspiciously low relative to the known group size, retry WITHOUT membership (rely on include_subgroups=true alone) before trusting the result. A zero/one-page result on a known-large group is a probable auth/pagination bug — treat it as a bug signal, never as ground truth that "the group is actually empty."

Label Taxonomy

Taxonomy convention (decided 2026-07-05, #727): labels use the SINGLE-COLON form exclusively (priority:high, status:ready, area:vcs, type:chore, from:<agent>). The ::-scoped form (priority::high, GitLab scoped-labels) is DEPRECATED baseline-scaffold legacy and MUST NOT be introduced — this repo mirrors to GitHub, which has no scoped-label semantics (no mutual-exclusion enforcement), so :: yields zero benefit on the mirror while a migration would break every existing label reference and issue.

Priority Labels

• priority:critical — blocking production or users
• priority:high — important, schedule this sprint
• priority:medium — plan for next sprint
• priority:low — backlog, nice-to-have

Status Labels

• status:ready — defined, ready to pick up
• status:in-progress — actively being worked on
• status:review — MR/PR created, awaiting review
• status:blocked — waiting on external dependency

Area Labels

• area:frontend | area:backend | area:database
• area:ai | area:security | area:testing
• area:ci | area:infrastructure | area:compliance
• area:skills | area:vcs | area:harness

Type Labels

• bug | feature | enhancement | refactor
• chore | documentation | epic | discovery | carryover | broken-window
• carryover — auto-created for 2×SPIRAL or FAILED agent tasks; see scripts/lib/spiral-carryover.mjs.
• broken-window — knowingly-broken shipment, hard due-date, filed by session-end Phase 2.6 (#730/H5); see scripts/lib/spiral-carryover.mjs (createBrokenWindowIssue).

Provenance Labels

• from:<agent> — SHOULD be applied to any issue/MR created by an automated agent (e.g. from:discovery, from:reconcile), so operators can filter agent-authored items from human-authored ones. Single-colon form, per the taxonomy convention above.

Issue Linking (blocks / is_blocked_by)

GitLab's native issue-link types blocks and is_blocked_by (glab api -X POST projects/:id/issues/:issue_iid/links -f link_type=blocks|is_blocked_by) are a Premium/Ultimate license feature. On a Free/Core-tier GitLab instance this call returns HTTP 403 — a license-gate signal, not an auth/permission failure. Do not retry with different credentials or escalate as an auth bug.

Fallback (non-Premium instances):

1. Use relates_to instead — link_type=relates_to is available on every GitLab tier (no ordering semantics, just an unscoped relation). Same API shape, only the link_type value changes:

   glab api -X POST "projects/:id/issues/:issue_iid/links" \
     -f target_project_id=:id -f target_issue_iid=:other_iid -f link_type=relates_to
   

2. Document the blocking semantics in the issue body — since relates_to carries no ordering meaning, add an explicit ordering note to both issues, e.g. ⚠ Ordering: erst #<blocker_iid>, dann dieses Issue — blocks-Link nicht verfügbar (non-Premium).
3. Recognize the 403 as a license signal, not an auth error — before assuming a token/scope problem, try relates_to on the same project pair: if relates_to succeeds where blocks/is_blocked_by 403s, the license gate — not authentication — is the cause.

GitHub has no native issue-blocking relation at all — the body-ordering-note fallback in step 2 above is the standing convention there too, regardless of license tier (see "GitHub (gh)" below).

Common CLI Commands

glab issue list --label "status:ready" --per-page 10       # Ready to work on

glab issue close <IID>                                       # then VERIFY: glab issue view <IID> must show state=closed
glab issue note <IID> -m "Comment text"                    # Add comment

# MRs
glab mr list                                                # Open MRs
glab mr create --fill --draft                               # Create draft MR
glab mr merge <MR_IID>                                     # Merge MR

# Pipelines
glab pipeline list --per-page 5                            # Recent pipelines
glab pipeline status <ID>                                  # Pipeline details

# API (reads host from git remote automatically)
glab api "projects/$(glab repo view --output json | python3 -c "import json,sys; print(json.load(sys.stdin)['id'])")/issues?state=opened&per_page=50"
glab api "projects/$(glab repo view --output json | python3 -c "import json,sys; print(json.load(sys.stdin)['id'])")/milestones?state=active"

Label update caveat (PUT-replaces, not additive): glab issue update --label (and the underlying GitLab labels API) PUT-REPLACES the entire label set — it does not add to the existing set. To change a single label you must pass the FULL desired label list, or use the dedicated add/remove operations, which are themselves unreliable across glab versions. Preferred safe pattern: use --label (adds) together with --unlabel (removes) on glab issue update when your installed glab version supports both; otherwise read the current labels first, compute the full new set, and PUT once. The same PUT-replace semantics apply to glab mr update --label.

Close verification: after glab issue close <IID>, always verify the close actually landed — re-read the issue (glab issue view <IID>) and confirm state: closed in the output. A stale/wrong project ID or a silent 404 can report local success while closing nothing; a documented incident closed 32 issues into the void this way (project ID pointed at the wrong project — see "Dynamic Project Resolution" above for the re-resolve-each-session rule that prevents it).

Commit-body close-keyword footgun: GitLab (and GitHub) auto-close an issue when a commit pushed to the default branch contains a close keyword — close/closes/closed/fix/fixes/fixed/resolve/resolves/resolved — followed by #N ANYWHERE in the commit body, not just the subject line. This fires even inside a negation ("does NOT close #N") — the platform pattern-matches the keyword + issue reference; it does not parse English negation, so the negation offers no protection. Rule: when a commit body needs to MENTION an issue without closing intent, always use a non-closing reference — refs #N, part of #N, siehe #N — never a close-keyword verb next to the number, negated or not.

-f/--raw-field vs -F/--field on glab api: -f (--raw-field) sends a literal string value with no coercion and no @file expansion. -F (--field) interprets a value starting with @ as a file to read, and coerces bare true/false/null/numeric strings to their typed form. Prefer -f for literal values — it avoids an unintended @-expansion when a value happens to start with @ (e.g. an @mention in a comment body).

Template-First Enforcement (PSA-005 + #519)

Pattern 3 of the gsd Pattern Adoption (Issue #519) registers a PreToolUse hook hooks/pre-bash-templates-first.mjs that blocks gh|glab pr|mr|issue create|new Bash calls when the current session contains no prior Read on a matching template file.

When this matters: before you or a subagent opens an MR, PR, or issue via CLI, a matching template must have been read in the current session:

• GitHub: .github/PULL_REQUEST_TEMPLATE.md / .github/ISSUE_TEMPLATE*
• GitLab: .gitlab/merge_request_templates/Default.md / .gitlab/issue_templates/*

Accepted template paths are configured in .orchestrator/policy/templates-policy.json (versioned, operator-editable). Default behaviour:

• enforcement: "block" — hook exits 2 when no prior template Read is found
• Allow-list of host-specific template globs (GitHub + GitLab by default)
• bypass_patterns — list of command substrings that skip the hook (e.g. CI/bot calls)

Bypass options for the current session (when the hook blocks unexpectedly):

1. Read the template first — re-run the create call after a Read on the template path; the hook re-evaluates and sees the Read.
2. Session acknowledgement — write .orchestrator/runtime/templates-acknowledged.json containing { sessionId, acknowledgedAt }; the hook allows all subsequent create calls in this session.

What the hook mechanically enforces (what this skill previously documented as convention only):

• "Template-first" for every new MR/PR/issue
• Prevents convention drift across repos by turning the documentation requirement into a hard gate — the same shift from rule to mechanism that PSA-003 made for destructive commands

If the hook blocks incorrectly, follow this sequence:

1. Read the template — retry the create call.
2. If the hook still blocks, open a bug issue against hooks/pre-bash-templates-first.mjs with reproduce steps (command, session ID, template path that should have matched).

Issue/MR Creation Checklist (with template-first gate active)

# 1. Read the relevant template first (satisfies the hook)
# GitLab MR
Read .gitlab/merge_request_templates/Default.md

# GitHub PR
Read .github/PULL_REQUEST_TEMPLATE.md

# 2. Then create — hook now passes
glab mr create --title "..." --description "..."
gh pr create --title "..." --body "..."
