push-ci

name	push-ci
description	Push to remote and monitor CI. Validates branch safety, executes git push WITH explicit user approval, then monitors CI run status via gh CLI. Use when: user says 'push', 'push and watch CI', 'ship it', 'push-ci'. Not for: committing (use /smart-commit), creating PRs (use /create-pr), merging (use /merge-prep).

Push & CI Monitor

Push to remote with user approval, then monitor CI run until completion.

Authorization

⚠️ This skill is one of two authorized paths for Claude to execute `git push`.
⚠️ The other is /epic-merge (force-push --force-with-lease for stacked PR chains, per-iteration AskUserQuestion gate).
⚠️ All other skills and rules MUST output push commands only (not execute).
⚠️ Push REQUIRES explicit user approval via AskUserQuestion — no exceptions.

Rule	This Skill	/epic-merge	All Other Skills
git push	Execute (after user approval)	Forbidden (uses --force-with-lease only)	Forbidden (output only)
git push --force	Forbidden	Forbidden	Forbidden
git push --force-with-lease	Forbidden	Execute (after per-iteration AskUserQuestion)	Forbidden
Push to protected branches (main/master/develop/release/*)	Warn + pre-approval via AskUserQuestion (terminal hook is final gate)	N/A (only pushes to PR head branches)	Forbidden

Defense in Depth: Push Safety

Layer	Mechanism	Scope	Reliability
L1: git pre-push hook	pre-push-gate.sh reads /dev/tty for terminal confirmation	Protected branches + non-fast-forward detection	Immune to Claude Code permission caching
L2: AskUserQuestion	In-session advisory prompt before push	All pushes	May be auto-approved by session caching (advisory only)
L3: git-workflow rules	Claude forbidden from raw git push	All contexts	Behavioral enforcement

Primary gate: pre-push-gate.sh (install via /install-scripts). This script runs as a git pre-push hook and prompts the developer directly via /dev/tty, which is immune to Claude Code's permission caching. AskUserQuestion remains as an advisory UX layer but is not the authorization gate — the git hook is.

Why AskUserQuestion alone is insufficient: Session permission caching can auto-approve AskUserQuestion calls in long-running sessions, especially with -c continue mode. See GitHub Issue #15400.

Workflow

    participant C as Claude
    participant U as User
    participant GH as GitHub

    C->>C: Phase 0: Preflight
    alt Protected branch detected
        C->>U: ⚠️ Warning + ask pre-approval
        U->>C: Continue / Abort
    end
    C->>U: Phase 1: Show push plan + ask approval
    U->>C: Approve / Reject
    alt Approved
        C->>GH: Execute git push
        C->>C: Phase 2: Execute git push
        C->>GH: Phase 3: Delegate to /watch-ci
        GH-->>C: CI verdict
    else Rejected
        C->>U: Abort (no push)
    end

Phase 0: Preflight

Run all checks. Hard-abort on infrastructure failures; warn-and-confirm on protected branches.

# 1. Current branch
BRANCH=$(git rev-parse --abbrev-ref HEAD)

# 2. Protected branch detection
# If main, master, develop, or release/* → warn + AskUserQuestion pre-approval
# (do NOT hard-abort; let user decide)

# 3. Remote exists
git ls-remote --exit-code origin >/dev/null 2>&1

# 4. Working tree status
git status --short

# 5. Commits ahead of remote
git rev-list --count origin/$BRANCH..HEAD 2>/dev/null || echo "new branch"

# 6. Local HEAD SHA (for CI run matching later)
HEAD_SHA=$(git rev-parse HEAD)

Check	Pass	Fail
Branch is not protected	Continue	Warn + AskUserQuestion (see below)
Remote exists	Continue	Abort: "No remote 'origin' configured"
Has commits ahead	Continue	Abort: "Nothing to push (0 commits ahead)"

Protected branch pre-approval flow (advisory — terminal hook remains final gate):

When branch is main, master, develop, or release/*:

1. Show warning with branch name and commit count
2. Use AskUserQuestion with options:
   • "Continue — push to <branch>" — proceed to Phase 1
   • "Abort" — stop immediately
3. If user aborts → stop. If user continues → proceed to Phase 1 (push approval asked separately). Note: the git pre-push hook will still require terminal confirmation via /dev/tty as the final authorization gate.

Phase 1: Push Plan + User Approval

Present push summary and ask user for explicit approval using AskUserQuestion:

## Push Plan

- Branch: `<branch>`
- Remote: `origin`
- Commits: <N> ahead
- HEAD: `<sha>`

Command to execute: `git push origin <branch>`

Gate: Use AskUserQuestion with options:

• "Approve push" — proceed to execute
• "Abort" — stop, do not push

If user rejects → stop immediately. Do NOT retry or persuade.

Phase 2: Execute Push

After user approval:

Command assembly (deterministic):

# Build and execute push command (ONLY after explicit approval)
# ⚠️ Always unset ALLOW_PUSH_PROTECTED to prevent env inheritance bypassing the hook.
# Only set ALLOW_FORCE_WITH_LEASE when --force-with-lease is explicitly requested.
if [[ "$FORCE_WITH_LEASE" == "true" ]]; then
  if [[ "$SET_UPSTREAM" == "true" ]]; then
    ALLOW_PUSH_PROTECTED= ALLOW_FORCE_WITH_LEASE=1 git push --force-with-lease -u origin "$BRANCH"
  else
    ALLOW_PUSH_PROTECTED= ALLOW_FORCE_WITH_LEASE=1 git push --force-with-lease origin "$BRANCH"
  fi
else
  if [[ "$SET_UPSTREAM" == "true" ]]; then
    ALLOW_PUSH_PROTECTED= ALLOW_FORCE_WITH_LEASE= git push -u origin "$BRANCH"
  else
    ALLOW_PUSH_PROTECTED= ALLOW_FORCE_WITH_LEASE= git push origin "$BRANCH"
  fi
fi
# If push fails (non-zero exit) → stop immediately, report error, do NOT proceed to CI

--set-upstream auto-detect: If git rev-parse --abbrev-ref --symbolic-full-name @{u} fails (no upstream), add -u automatically.

Phase 3: Monitor CI (delegation)

After successful push, invoke /watch-ci to monitor CI runs:

• Pass --sha <HEAD_SHA> and --branch <BRANCH> from Phase 0
• Pass --timeout from arguments (default 10)
• /watch-ci runs in Monitor streaming mode (default) — Claude receives progress notifications and reports verdict on completion
• /watch-ci handles run discovery, quick-check, monitoring, retry logic, and verdict reporting

This delegation keeps push authorization logic separate from read-only CI monitoring. See @skills/watch-ci/SKILL.md for CI monitoring details.

Arguments

Argument	Description	Default
--timeout <min>	CI watch timeout in minutes	10
--force-with-lease	Use --force-with-lease instead of regular push	off
--set-upstream	Add -u flag (first push of new branch)	auto-detect

--force is NOT supported. Force push is always forbidden.

Prohibited

- Executing git push WITHOUT prior user approval via AskUserQuestion
- Suggesting or executing git push --force (ever)
- Pushing to protected branches WITHOUT explicit user pre-approval via AskUserQuestion
- Setting ALLOW_PUSH_PROTECTED=1 (this skill must NEVER set this env var; it is reserved for manual developer use only)
- Auto-triggering this skill (disable-model-invocation: true)
- Skipping preflight checks
- Skipping `/watch-ci` delegation after successful push

Verification

• Preflight passed (branch + remote + commits)
• User approved push via AskUserQuestion
• Push executed successfully
• CI monitoring delegated to /watch-ci with correct SHA + branch

Examples

Input: /push-ci
Phase 0: Preflight — branch feat/auth, 3 commits ahead, remote OK
Phase 1: Show plan → user approves
Phase 2: git push origin feat/auth
Phase 3: /watch-ci --sha <HEAD> --branch feat/auth (Monitor streaming — receive progress notifications)

Input: /push-ci --timeout 15
Phase 0-1: Same as above
Phase 2: git push
Phase 3: /watch-ci --sha <HEAD> --branch <branch> --timeout 15

Input: /push-ci --force-with-lease
Phase 0: Preflight (warns on protected branches)
Phase 1: Show plan with --force-with-lease → user approves
Phase 2: git push --force-with-lease origin feat/rebase-cleanup
Phase 3: CI monitoring

Input: /push-ci (on main branch)
Phase 0: Preflight — ⚠️ "main is a protected branch" → AskUserQuestion pre-approval
User: Continue → proceed
Phase 1: Show plan → user approves push
Phase 2: git push origin main
Phase 3: /watch-ci (Monitor streaming — receive progress notifications)
