Pipeline Plan 58

The plan file is in a sensitive directory. Let me output the plan directly instead.

The implementation plan has been written to .claude/pipeline-artifacts/plan.md. Here's the summary:

Implementation Plan: Automated Dependency Updates (#58)

Files to Modify

File	Action	Purpose
scripts/sw-deps.sh	Create	Core module — PR detection, risk classification, auto-merge
scripts/sw-deps-test.sh	Create	Unit tests — version parsing, risk scoring, merge decisions
scripts/sw-daemon.sh	Modify	Add daemon_poll_dependabot() in sweep loop + config loading
scripts/sw	Modify	Add deps subcommand to CLI router
.claude/daemon-config.json	Modify	Add dependabot configuration section
.github/workflows/shipwright-deps.yml	Create	CI-native Dependabot PR handling
package.json	Modify	Register test suite

Implementation Steps

Step 1: scripts/sw-deps.sh (~600 lines)

Core functions:

• deps_fetch_prs() — Fetch open PRs by app/dependabot and app/renovate via gh pr list, cached (TTL 300s)
• deps_classify_risk() — Parse PR titles for semver bumps: "Bump <pkg> from <old> to <new>". Classify as patch (score=10, low risk), minor (score=50, medium), major (score=90, high), or group (score=60, medium)
• deps_select_strategy() — Map risk to template: patch→fast+auto_merge, minor→standard+CI-gated, major→full+human review
• deps_check_breaking_changes() — Scan PR body for "BREAKING", "deprecation", "removed" keywords; elevate risk if found
• deps_run_tests() — Checkout PR branch, run test suite, capture results
• deps_auto_merge() — Approve + merge eligible PRs, flag others with comment
• deps_process_all() — Orchestrate: fetch → classify → check → test → merge/flag; emit deps.sweep event

CLI subcommands: scan, review <pr>, merge <pr>, status

Step 2: Daemon Integration

In sw-daemon.sh:

• load_config(): Add DEPS_ENABLED, DEPS_AUTO_MERGE, DEPS_POLL_INTERVAL, DEPS_BATCH_SIZE from dependabot.* config
• daemon_poll_loop() (~line 4898): Add Dependabot sweep every N cycles alongside existing patrol
• New daemon_poll_dependabot(): Sources sw-deps.sh, runs deps_process_all, respects NO_GITHUB, rate limits, and MAX_PARALLEL

Step 3: CLI Router

Add deps) case in scripts/sw dispatching to sw-deps.sh

Step 4: Configuration

"dependabot": {
    "enabled": true,
    "auto_merge": true,
    "poll_interval_cycles": 3,
    "risk_thresholds": {
        "patch": {"template": "fast", "auto_merge": true, "auto_approve": true},
        "minor": {"template": "standard", "auto_merge": true, "auto_approve": false},
        "major": {"template": "full", "auto_merge": false, "auto_approve": false}
    },
    "max_auto_merges_per_sweep": 3
}

Step 5: GitHub Actions Workflow

Triggers on pull_request from dependabot[bot], runs tests, auto-merges patch-level updates

Step 6: Test Suite (~500 lines)

7 test categories: version parsing (6 tests), risk classification (5), strategy selection (4), breaking change detection (4), merge decisions (4), event emission (3), integration (3). Uses mock gh binary, NO_GITHUB=true, standard PASS/FAIL harness.

Task Checklist

• Task 1: Create sw-deps.sh boilerplate + CLI router
• Task 2: Implement deps_fetch_prs()
• Task 3: Implement deps_classify_risk()
• Task 4: Implement deps_select_strategy()
• Task 5: Implement deps_check_breaking_changes()
• Task 6: Implement deps_run_tests()
• Task 7: Implement deps_auto_merge() + deps_process_all()
• Task 8: Daemon integration (config + sweep loop)
• Task 9: CLI router update
• Task 10: daemon-config.json update
• Task 11: GitHub Actions workflow
• Task 12: Tests — version parsing + risk classification
• Task 13: Tests — strategy, breaking changes, merge decisions
• Task 14: Tests — events + integration flow
• Task 15: Register in package.json + verify npm test

Definition of Done

• Dependabot PRs detected and classified by risk (scan subcommand)
• Patch updates auto-merge after tests pass
• Major updates flagged for human review with comment
• Breaking change detection works
• All tests pass (sw-deps-test.sh + npm test)
• Bash 3.2 compatible (no associative arrays, no readarray, no ${var,,})
• Events emitted: deps.sweep, deps.merged, deps.flagged
