/pipeline — Pipeline Invocation

Usage

/pipeline auto-dev          # Run the auto-dev pipeline
/pipeline                   # List available pipelines
/pipeline resume            # Resume a halted pipeline

Behavior

List Mode (no arguments or --list flag)

Execute these steps to display available pipelines:

1. Scan built-in pipelines: Use Glob("workflows/*.yaml") (NOT templates/) to find all pipeline definitions
2. Extract metadata: For each YAML file found, use Bash to extract name and description:

   for f in workflows/*.yaml; do
     name=$(grep -m1 '^name:' "$f" | sed 's/^name: *//' | tr -d '"')
     desc=$(grep -m1 '^description:' "$f" | sed 's/^description: *//' | tr -d '"')
     echo "  $name — $desc"
   done
   

3. Scan template pipelines: Use Glob("templates/workflows/*.yaml") for template examples
4. Display formatted output:

   Available pipelines:
     {name} — {description}
     {name} — {description}
   
   Template pipelines (in templates/workflows/):
     {name} — {description}
   

5. If no pipelines found, display: "No pipelines found in workflows/ directory."
6. If YAML parsing fails for a file, skip it and show: {filename} — (parse error, skipped)

Run Mode (with pipeline name)

1. Validate pipeline exists: workflows/{name}.yaml
2. Load and validate YAML structure:
   • Required fields: name, description, steps[]
   • Each step has either skill: or prompt: (not both)
   • Referenced skills exist in .codex/skills/
   • Skill names must match ^[a-z0-9-]+$ (kebab-case only) — reject path traversal attempts
3. Announce: [Pipeline] Starting {name} — {step_count} steps
4. Execute steps top-to-bottom:
   • Skill steps (skill: name): Invoke via Skill tool — Skill(skill: "{name}")
   • Prompt steps (prompt: text): Execute the described action using appropriate agents/tools
   • Foreach steps (foreach: collection): Iterate over collection from previous step output
   • Permission mode: When spawning agents, pass mode: "bypassPermissions" in the Agent tool call if the session uses bypassPermissions. Without explicit mode, CC defaults to acceptEdits.
5. Report completion or failure

Resume Mode (/pipeline resume)

1. Scan /tmp/.codex-pipeline-*-{PPID}.json for state files
2. If none found: "No halted pipelines found."
3. If found: display pipeline name, failed step, error message
4. Options:
   • Retry — Re-execute the failed step
   • Skip — Mark failed step as skipped, continue to next
   • Abort — Delete state file, cancel pipeline
5. On resume: execute from the failed step

State Tracking

Track per-step state:

{
  "pipeline": "{name}",
  "started": "ISO-8601",
  "status": "running|completed|halted",
  "current_step": 0,
  "steps": [
    {"name": "triage", "status": "completed", "duration_ms": 5000},
    {"name": "plan", "status": "running"}
  ]
}

State saved to /tmp/.codex-pipeline-{name}-{PPID}.json on failure.

Error Handling

• Pipeline not found → list available pipelines with suggestion
• YAML parse error → report with line number
• Step failure (error: halt-and-report) → stop execution, save state, report failure with context
• All file writes delegated to subagents per R010
