 # /conductor-new-track
 
 Create a new track in the conductor system. This is a Tier 1 (Orchestrator) operation.
+The quality of the spec and plan directly determines whether Tier 3 workers can execute
+without confusion. Vague specs produce vague implementations.
 
 ## Prerequisites
 - Read `conductor/product.md` and `conductor/product-guidelines.md` for product alignment
 - Read `conductor/tech-stack.md` for technology constraints
+- Consult architecture docs in `docs/` when the track touches core systems:
+  - `docs/guide_architecture.md`: Threading, events, AI client, HITL mechanism
+  - `docs/guide_tools.md`: MCP tools, Hook API, ApiHookClient
+  - `docs/guide_mma.md`: Tickets, tracks, DAG engine, worker lifecycle
+  - `docs/guide_simulations.md`: Test framework, mock provider, verification patterns

+
+Before writing a single line of spec, you MUST audit the actual codebase to understand

+
+1. **Map the target area**: Use `py_get_code_outline` on every file the track will touch.
+   Identify existing functions, classes, and their line ranges.
+2. **Read key implementations**: Use `py_get_definition` on functions that are relevant
+   to the track's goals. Understand their signatures, data structures, and control flow.
+3. **Search for existing work**: Use `Grep` to find symbols, patterns, or partial
+   implementations that may already address some requirements.
+4. **Check recent changes**: Use `get_git_diff` on target files to understand what's
+   been modified recently and by which tracks.

+- ALWAYS link to relevant architecture docs
+- Reference actual variable names, dict keys, and class names from the codebase
+
+### 7. Create plan.md — The Surgical Plan
+
+Each task must be specific enough that a Tier 3 worker on a lightweight model
+can execute it without needing to understand the overall architecture.

+**Rules for writing tasks:**
 
-### 7. Update Track Registry
-If `conductor/tracks.md` exists, add the new track entry.
+1. **Reference exact locations**: "In `_render_mma_dashboard` (gui_2.py:2700-2701)"
+   not "in the dashboard."
+2. **Specify the API**: "Use `imgui.progress_bar(value, ImVec2(-1, 0), label)`"
+   not "add a progress bar."
+3. **Name the data**: "Read from `self.mma_streams` dict, keys prefixed with `'Tier 3'`"
+   not "display the streams."
+4. **Describe the change shape**: "Replace the single text box with four collapsible sections"
+   not "improve the display."
+5. **State thread safety**: "Push via `_pending_gui_tasks` with lock" when the task
+   involves cross-thread data.
+6. **For bug fixes**: List specific root cause candidates with code-level reasoning,
+   not "investigate and fix."
+7. **Each phase ends with**: A test task and a verification task.
 
 ### 8. Commit
 ```
 conductor(track): Initialize track '{track_name}'
 ```
 
+## Anti-Patterns (DO NOT do these)
+
+- **Spec that describes features without checking if they exist** → produces duplicate work
+- **Task that says "implement X" without saying WHERE or HOW** → worker guesses wrong
+- **Plan with no line references** → worker wastes tokens searching
+- **Spec with no architecture doc links** → worker misunderstands threading/data model
+- **Tasks scoped too broadly** → worker tries to do too much, fails
+- **No "Current State Audit"** → entire track may be re-implementing existing code
+
 ## Important
 - Do NOT start implementing — track initialization only
 - Implementation is done via `/conductor-implement`

+## The Surgical Methodology
+
+When creating or refining tracks, follow this protocol to produce specs that
+lesser-reasoning models can execute without confusion:
+
+### 1. Audit Before Specifying
+NEVER write a spec without first reading the actual code. Use `py_get_code_outline`,
+`py_get_definition`, `Grep`, and `get_git_diff` to build a map of what exists.
+Document existing implementations with file:line references in a "Current State Audit"
+section. This prevents specs that ask to re-implement existing features.
+
+### 2. Identify Gaps, Not Features
+The spec should focus on what's MISSING, not what the track "will build."
+Frame requirements as: "The existing `_render_mma_dashboard` (gui_2.py:2633-2724)
+has a token usage table but no cost estimation column. Add cost tracking."
+Not: "Build a metrics dashboard with token and cost tracking."
+
+### 3. Write Worker-Ready Tasks
+Each task in the plan must be executable by a Tier 3 worker on a lightweight model
+(gemini-2.5-flash-lite) without needing to understand the overall architecture.
+This means every task must specify:
+- **WHERE**: Exact file and line range to modify
+- **WHAT**: The specific change (add function, modify dict, extend table)
+- **HOW**: Which API calls, data structures, or patterns to use
+- **SAFETY**: Thread-safety constraints if cross-thread data is involved
+
+### 4. Reference Architecture Docs
+Every spec should link to the relevant `docs/guide_*.md` section so implementing
+agents have a fallback when confused about threading, data flow, or module interactions.
+
+### 5. Map Dependencies
+Explicitly state which tracks must complete before this one, and which tracks
+this one blocks. Include execution order in the spec.
+
+### 6. Root Cause Analysis (for fix tracks)
+Don't write "investigate and fix X." Instead, read the code, trace the data flow,
+and list specific root cause candidates with code-level reasoning:
+"Candidate 1: `_queue_put` (line 138) uses `asyncio.run_coroutine_threadsafe` but
+the `else` branch uses `put_nowait` which is NOT thread-safe from a thread-pool thread."
+
 ## Limitations
 - Read-only tools only: Read, Glob, Grep, WebFetch, WebSearch, Bash (read-only ops)
 - Do NOT execute tracks or implement features
-- Do NOT write code or edit files
+- Do NOT write code or edit files (except track spec/plan/metadata)
 - Do NOT perform low-level bug fixing
 - Keep context strictly focused on product definitions and high-level strategy

+## The Surgical Methodology
+
+When creating or refining tracks, you MUST follow this protocol:
+
+### 1. MANDATORY: Audit Before Specifying
+NEVER write a spec without first reading the actual code using your tools.
+Use `get_code_outline`, `py_get_definition`, `grep_search`, and `get_git_diff`
+to build a map of what exists. Document existing implementations with file:line
+references in a "Current State Audit" section in the spec.
+
+**WHY**: Previous track specs asked to implement features that already existed
+(Track Browser, DAG tree, approval dialogs) because no code audit was done first.
+This wastes entire implementation phases.
+
+### 2. Identify Gaps, Not Features
+Frame requirements around what's MISSING relative to what exists:
+GOOD: "The existing `_render_mma_dashboard` (gui_2.py:2633-2724) has a token
+usage table but no cost estimation column."
+BAD: "Build a metrics dashboard with token and cost tracking."
+
+### 3. Write Worker-Ready Tasks
+Each plan task must be executable by a Tier 3 worker on gemini-2.5-flash-lite
+without understanding the overall architecture. Every task specifies:
+- **WHERE**: Exact file and line range (`gui_2.py:2700-2701`)
+- **WHAT**: The specific change (add function, modify dict, extend table)
+- **HOW**: Which API calls or patterns (`imgui.progress_bar(...)`, `imgui.collapsing_header(...)`)
+- **SAFETY**: Thread-safety constraints if cross-thread data is involved
+
+### 4. For Bug Fix Tracks: Root Cause Analysis
+Don't write "investigate and fix." Read the code, trace the data flow, list
+specific root cause candidates with code-level reasoning.
+
+### 5. Reference Architecture Docs
+Link to relevant `docs/guide_*.md` sections in every spec so implementing
+agents have a fallback for threading, data flow, or module interactions.
+
+### 6. Map Dependencies Between Tracks
+State execution order and blockers explicitly in metadata.json and spec.
