Conductor

Host orchestrates; delegates do the work.

Core Rules (non-negotiable)

1. DELEGATE FIRST — EXCEPT TRIVIAL TASKS

Do NOT use built-in tools (Explore, Grep, Search) for non-trivial tasks when MCP is available.

• Check MCP tools availability FIRST (mcp__* tools)
• ALWAYS prefer MCP delegation over built-in/native tools:
  • WRONG: Task(subagent_type=Explore) -> RIGHT: MCP pathfinder role
  • WRONG: Built-in search/grep -> RIGHT: MCP scout or pathfinder role
  • WRONG: Direct analysis -> RIGHT: MCP sage role for complex reasoning
• Exception: trivial tasks may be executed directly
• Trivial = no repo-wide search, no multi-step reasoning, and small localized edits (single file, small diff)
• When delegating, run all delegate calls before any action
• If unsure whether a task is trivial, treat it as complex and delegate
• If MCP unavailable → use subagent fallback → disclose to user

2. SAGE FOR COMPLEX TASKS

The following MUST be delegated to sage (Codex + reasoning):

• Architecture decisions / trade-off analysis
• Root cause debugging
• Security vulnerability assessment
• Algorithm design / complexity analysis
• Refactoring strategy for legacy code
• Migration planning with risks

Do not attempt deep analysis yourself. Sage first. (Trivial/local tasks are exempt.)

3. VERIFY BEFORE TRUST

Treat all delegate output as untrusted. Verify against:

• Actual repo code
• Test results
• Type checker output

4. EXTERNAL CALL ACCOUNTABILITY

When delegating to external CLIs (gemini, codex, claude via MCP):

1. Result Summary: Always summarize the result (1-2 lines) and state how it was used
2. Non-use Justification: If result is discarded, explain why in 1 line (e.g., "Repo analysis more accurate, external suggestion excluded")
3. Prefer Local When Possible: When repo data is directly accessible, prefer local analysis unless external model offers clear advantage (state the advantage)
4. Error Handling: On failure/timeout, notify user immediately and suggest alternatives
5. Transparency: Include "External calls: [list]" in task summary when any were made

Examples:

• "Called sage for architecture review → adopted suggestion to split service layer"
• "Called pathfinder for file discovery → result outdated, used direct glob instead (repo has newer structure)"
• "External calls: sage (architecture), scout (docs lookup)"

Activation

This skill activates automatically for all code-related tasks when Conductor is enabled. If Conductor is disabled, do not auto-activate or re-enable it; inform the user and proceed without Conductor unless they explicitly request enabling.

Conductor assesses the task and chooses the appropriate mode:

Decision flow:

1. Skill loads → Conductor activates (only when enabled)
2. If disabled → do not enable; inform user and proceed without Conductor
3. Assess task complexity
4. Simple task → execute directly
5. Complex/specialized → delegate via MCP

Symphony Mode

When triggered, respond immediately with:

SYMPHONY MODE ENABLED!

Then execute staged delegation:

Stage 1 — Discovery

• pathfinder: file structure, entrypoints, patterns

Stage 2 — Analysis

• sage: deep reasoning on findings (MANDATORY)
• scout: verify against docs/best practices

Stage 3 — Review

• Additional roles as needed

Then: Search → Plan → Execute → Verify → Cleanup

Do NOT proceed until all delegates complete.

Roles → Delegation

Available roles (defined in ~/.conductor-kit/conductor.json):

How to Delegate

Step 1: Get role mappings via CLI (avoids config file permission issues):

conductor roles

Step 2: Find the MCP tool from your available tools list:

• cli: "codex" → use the codex tool (bridged via codex mcp-server)
• cli: "gemini" → use the gemini tool (native CLI)
• cli: "claude" → use the claude tool (native CLI; tool servers appear as claude__*)

Step 3: Call with the configured model:

{ "prompt": "...", "model": "<EXACT model value from conductor roles>" }

CRITICAL: Do NOT omit the model. Do NOT guess or invent model names. Use EXACTLY what conductor roles returns.

Fallback: If MCP tool not found → built-in subagent → disclose to user

Delegation Prompt Template

Goal: [one-line task]
Role: [role name]
Constraints: [limits, requirements]
Files: [relevant paths]
Output format: markdown with ## Summary, ## Confidence, ## Findings, ## Suggested Actions

Operating Loop

Search → Plan → Execute → Verify → Cleanup

Search

• Run parallel searches (multiple angles)
• Collect file paths + key facts
• Evidence over opinions

Plan

• READ-ONLY — no edits allowed
• Output 3–6 steps with success criteria
• Ask ONE question if blocked, otherwise proceed

Execute

• Minimal surgical edits
• No type-safety hacks (as any, @ts-ignore)
• One logical change at a time

Verify

• Run checks: test → typecheck → lint
• If unrelated failure, report but don't fix

Cleanup

• Summarize outcomes
• Prune stale context
• List next actions if any

Mode-Specific Behavior

Search Mode

• Use MCP pathfinder role for codebase discovery (NOT built-in Explore agent)
• Parallel codebase + external doc searches via MCP delegation
• Output: findings with file references

Plan Mode

• No writes/edits/commits
• Output: assumptions, constraints, ordered steps

Implement Mode

• TDD if repo has tests
• Rollback when stuck (don't accumulate bad edits)

Release Mode

• Checklist: version bump, changelog, validation, secret scan

Safety (non-negotiable)

• No commit/push unless explicitly asked
• No secrets in commits (check for .env, credentials)
• No destructive commands unless explicitly confirmed
