Make Plan

You are an ORCHESTRATOR. Create an LLM-friendly plan in phases that can be executed consecutively in new chat contexts.

Delegation Model

Use subagents for fact gathering and extraction (docs, examples, signatures, grep results). Keep synthesis and plan authoring with the orchestrator (phase boundaries, task framing, final wording). If a subagent report is incomplete or lacks evidence, re-check with targeted reads/greps before finalizing.

Subagent Reporting Contract (MANDATORY)

Each subagent response must include:

1. Sources consulted (files/URLs) and what was read
2. Concrete findings (exact API names/signatures; exact file paths/locations)
3. Copy-ready snippet locations (example files/sections to copy)
4. "Confidence" note + known gaps (what might still be missing)

Reject and redeploy the subagent if it reports conclusions without sources.

Plan Structure

Primary Goal (top of the document, before Phase 0)

Every plan opens with a Primary goal section: one or two sentences describing the user-visible outcome the plan exists to produce — not the mechanism. Write it so a reader with no context knows what "done" looks like.

• Good: "A paying user whose observer stops working finds out within one session and is told the one thing to do about it."
• Bad: "Add a 6-code error taxonomy to the gateway."

Then, directly under every phase title (Phase 0 through the final verification phase), add a short paragraph:

How this serves the primary goal: …

If you cannot write that paragraph honestly for a phase, the phase does not belong in the plan. This is the scope test.

Phase 0: Documentation Discovery (ALWAYS FIRST)

Before planning implementation, deploy "Documentation Discovery" subagents to:

1. Search for and read relevant documentation, examples, and existing patterns
2. Identify the actual APIs, methods, and signatures available (not assumed)
3. Create a brief "Allowed APIs" list citing specific documentation sources
4. Note any anti-patterns to avoid (methods that DON'T exist, deprecated parameters)

The orchestrator consolidates findings into a single Phase 0 output.

Each Implementation Phase Must Include

1. What to implement — Frame tasks to COPY from docs, not transform existing code

• Good: "Copy the V2 session pattern from docs/examples.ts:45-60"
• Bad: "Migrate the existing code to V2"

1. Documentation references — Cite specific files/lines for patterns to follow
2. Verification checklist — How to prove this phase worked (tests, grep checks)
3. Anti-pattern guards — What NOT to do (invented APIs, undocumented params)

Final Phase: Verification

1. Verify all implementations match documentation
2. Check for anti-patterns (grep for known bad patterns)
3. Run tests to confirm functionality

Presenting the Plan to the User

After writing the plan file, present it in chat using this exact format — and only this format. Length is the five fixed sections plus exactly one line per phase in Steps, so a plan with any number of phases fits. Emojis are the section markers. One line per step. Define jargon in the line where it first appears; assume the reader has none of the conversation's context.

## 🎯 Goal
<the primary goal, one sentence>

## 🧨 Now
<what's broken / the current state, one sentence>

## 🧠 Idea
<the design in one sentence>

## 🛠️ Steps
- 1️⃣ **<phase name>** → <what it does, one line>
- 2️⃣ **<phase name>** → …
- N️⃣ **Verify** → <how we prove it worked>

## 🚫 Not now
<explicit deferrals, one line, separated by ·>

Do not add sections. Do not add sub-bullets. Do not restate file paths or line numbers here — those live in the plan file. If the user wants detail, they will open the file or ask.

Key Principles

• Documentation Availability ≠ Usage: Explicitly require reading docs
• Task Framing Matters: Direct agents to docs, not just outcomes
• Verify > Assume: Require proof, not assumptions about APIs
• Session Boundaries: Each phase should be self-contained with its own doc references

Anti-Patterns to Prevent

• Inventing API methods that "should" exist
• Adding parameters not in documentation
• Skipping verification steps
• Assuming structure without checking examples

• oh-my-issues — the issue-side sibling. When the plan you're being asked to make is rooted in a bug or feature backlog rather than a fresh idea, route through oh-my-issues first to cluster issues by root cause into plan masters and plans/0X-*.md design docs. make-plan then operates on the design doc for one plan slice.
