mco-cli

name: mco-cli description: Use mco to orchestrate multi-provider agent execution (run/review), choose result mode (artifact/stdout/both), and return user-readable output by default.

MCO CLI Skill

When to use

Use this skill when you need to:

• Run one or more coding agents in parallel from a single CLI entrypoint.
• Execute repository review tasks with severity-based decisions.
• Return user-readable result summaries (default non-JSON output).
• Produce machine-readable JSON for upstream automation.

Core commands

1) General execution

./mco run \
  --repo . \
  --prompt "<task>" \
  --providers claude,codex,qwen \
  --result-mode stdout

Use for generic agent tasks. This mode does not require findings schema.

2) Review execution

./mco review \
  --repo . \
  --prompt "<review task>" \
  --providers claude,qwen \
  --result-mode stdout

Use for bug/security/test-gap style review scenarios.

3) Strict gate review (CI style)

./mco review \
  --repo . \
  --prompt "<review task>" \
  --providers claude,codex \
  --strict-contract \
  --result-mode artifact \
  --json

Use when machine-enforced findings contract is required.

Result mode policy

• artifact:
  • Writes user-facing artifact files (summary.md, decision.md, findings.json, run.json).
  • Best for CI/audit.
• stdout:
  • Returns results directly to caller output.
  • Best for chat/agent UX rendering.
• both:
  • Writes artifacts and returns detailed stdout payload.

Output policy for user-facing responses

When returning to end users:

1. Prefer non-JSON stdout output from mco for readability.
2. If JSON is required by caller, parse and reformat into:
   • Execution Summary
   • Provider Details
   • Risk/Findings Summary
   • Next Actions
3. Never dump raw event streams unless user explicitly asks for raw logs.

Recommended defaults

• --result-mode stdout for interactive agents.
• --result-mode artifact --json for CI pipelines.
• --strict-contract only for gate workflows.
• Narrow scope with --target-paths for faster review.

Timeout and stability tips

• Use provider-specific stall timeout when one provider is slow:
  • --provider-timeouts qwen=900,codex=300
• Set review hard deadline for CI predictability:
  • --review-hard-timeout 1800
• Use unique --idempotency-key for each new execution intent.

Failure handling

If a provider fails:

1. Report per-provider success/final_error/parse_reason.
2. Distinguish transport/auth errors from parse/contract issues.
3. Continue with successful providers (wait-all behavior).

Minimal response template (to user)

Use this structure in final answers:

1. Execution overview (decision, terminal_state, success/failure count)
2. Provider-by-provider status
3. Key findings grouped by severity
4. Actionable next steps
