Do One Thing Well -Focused experts with clear boundaries, not monoliths. When something goes wrong in a monolith, you cannot tell which part failed. Focused experts are easier to debug, test, and improve independently. +- Understand the user's intent beyond their literal request +- Analyze who will use this expert and in what contexts +- Define what makes this expert succeed vs. fail +- Identify the domain knowledge the expert needs +- Produce 3 realistic test queries that represent actual usage -### 2. Trust the LLM, Define Domain Knowledge -Provide domain knowledge (policies, rules, constraints), not step-by-step procedures. The LLM knows how to reason and converse. What it does not know is your specific domain — that is what instructions should contain. +## Investigation -### 3. Let Them Collaborate -Modular experts that delegate, not monoliths. The same focused expert works across different contexts. One person improves one expert while another builds a different one. Test each independently. Replace one without touching others. +Before writing the plan, investigate thoroughly: +- If an existing perstack.toml path was provided, read it to understand the current state +- Read relevant workspace files to understand the domain +- Consider edge cases and boundary conditions -### 4. Keep It Verifiable -Instructions that anyone can read and predict behavior. If someone else cannot read your expert and predict its behavior, it is not verifiable. Include concrete rules, thresholds, and criteria rather than vague guidance. +## Domain Knowledge Extraction -### 5. Ship Early -Start minimal, iterate based on real usage. Real users reveal actual edge cases. A complex initial design often solves the wrong problems. Ship, observe, iterate. +The most critical part of your output. Domain knowledge is NOT generic facts — it is the set of constraints, values, and success criteria embedded in the user's request that define what makes THIS expert unique. -### 6. Thin Coordinators -Coordinators should only route work between delegates, not contain domain logic. If a coordinator needs to understand or transform data, that logic belongs in a delegate. +### How to extract domain knowledge -## Perstack Expert Model +The user's request is your primary source. Every word choice, qualifier, and constraint the user provides is a signal. Your job is to: -- **description** = public interface. Seen by delegating experts as a tool description. Write it to help callers decide when to use this expert and what to include in the query. -- **instruction** = private domain knowledge. Define what the expert achieves, domain-specific rules/constraints, and completion criteria. NOT step-by-step procedures. -- **skills** = MCP tools (file ops, exec, custom MCP servers). Always include attemptCompletion. -- **delegates** = other experts this one can call. Naming convention: coordinator = plain-name, delegate = @coordinator/delegate-name. -- **Context isolation**: delegates receive only the query, no parent context. Data exchange happens via workspace files. -- **Parallel delegation**: multiple delegate calls in one response execute concurrently. +1. **Read between the lines**: The user's phrasing reveals what they value. Adjectives, qualifiers, and explicit constraints are not decoration — they define the expert's identity and quality bar. +2. **Infer success keys**: When the user specifies multiple requirements, ask WHY they specified each one. The combination often reveals a strategic intent that no single requirement captures alone. +3. **Identify the wedge**: What makes this expert's output categorically different from a generic attempt at the same task? The answer is usually found in the tension between the user's constraints. +4. **Derive rules from values**: Convert the user's implicit values into explicit, actionable rules the expert can follow. "Polished" is a value; "no placeholder content, no TODO comments, every user-facing string is intentional" is a rule. -## Available Skill Types +### What domain knowledge IS -- **mcpStdioSkill** — stdio MCP server (most common).

Practical Over Ceremonial -Experts must produce real, usable output — not ceremony. A programming expert must write code, not documentation about code.
