description	Common agent patterns and templates for Claude Code. Use when implementing agents to follow proven patterns for Tasks integration, quality checks, and external model invocation via claudish CLI.

Agent Patterns

External Model Invocation Pattern

External AI models are invoked via Bash+claudish CLI by the orchestrator (e.g., /team). Agents do NOT need special blocks to support external models — the orchestrator calls claudish directly:

# Orchestrator calls claudish directly via Bash tool
claudish --model {MODEL_ID} --stdin --quiet < prompt.md > result.md

This is 100% reliable because it's a deterministic CLI invocation, not a prompt-based delegation.

Tasks Integration Pattern

Every agent must track workflow progress.

<critical_constraints>
  <tasks_requirement>
    You MUST use Tasks to track your workflow.

    **Before starting**, create task list:
    1. Phase 1 description
    2. Phase 2 description
    3. Phase 3 description

    **Update continuously**:
    - Mark "in_progress" when starting
    - Mark "completed" immediately after finishing
    - Keep only ONE task "in_progress" at a time
  </tasks_requirement>
</critical_constraints>

<workflow>
  <phase number="1" name="Phase Name">
    <step>Initialize Tasks with all phases</step>
    <step>Mark PHASE 1 as in_progress</step>
    <step>... perform work ...</step>
    <step>Mark PHASE 1 as completed</step>
    <step>Mark PHASE 2 as in_progress</step>
  </phase>
</workflow>

Quality Checks Pattern (Implementers)

<implementation_standards>
  <quality_checks mandatory="true">
    Before presenting code, perform these checks in order:

    <check name="formatting" order="1">
      <tool>Biome.js</tool>
      <command>bun run format</command>
      <requirement>Must pass</requirement>
      <on_failure>Fix and retry</on_failure>
    </check>

    <check name="linting" order="2">
      <tool>Biome.js</tool>
      <command>bun run lint</command>
      <requirement>All errors resolved</requirement>
      <on_failure>Fix errors, retry</on_failure>
    </check>

    <check name="type_checking" order="3">
      TypeScript
      bun run typecheck
      Zero type errors
      Resolve errors, retry
    

    
      Vitest
      bun test
      All tests pass
      Fix failing tests

Review Feedback Pattern (Reviewers)

<review_criteria>
  <feedback_format>
    ## Review: {name}

    **Status**: PASS | CONDITIONAL | FAIL
    **Reviewer**: {model}

    **Issue Summary**:
    - CRITICAL: {count}
    - HIGH: {count}
    - MEDIUM: {count}
    - LOW: {count}

    ### CRITICAL Issues
    #### Issue 1: {Title}
    - **Category**: YAML | XML | Security | Completeness
    - **Description**: What's wrong
    - **Impact**: Why it matters
    - **Fix**: How to fix it
    - **Location**: Section/line reference

    ### HIGH Priority Issues
    [Same format]

    ### Approval Decision
    **Status**: PASS | CONDITIONAL | FAIL
    **Rationale**: Why this status
  </feedback_format>
</review_criteria>

<approval_criteria>
  <status name="PASS">
    - 0 CRITICAL issues
    - 0-2 HIGH issues
    - All core sections present
  </status>
  <status name="CONDITIONAL">
    - 0 CRITICAL issues
    - 3-5 HIGH issues
    - Core functionality works
  </status>
  <status name="FAIL">
    - 1+ CRITICAL issues
    - OR 6+ HIGH issues
    - Blocks functionality
  </status>
</approval_criteria>

Orchestrator Phase Pattern (Commands)

<phases>
  <phase number="1" name="Descriptive Name">
    <objective>Clear statement of what this phase achieves</objective>

    <steps>
      <step>Mark PHASE 1 as in_progress in task list</step>
      <step>Detailed action step</step>
      <step>Detailed action step</step>
      <step>Mark PHASE 1 as completed</step>
    </steps>

    <quality_gate>
      Exit criteria - what must be true to proceed
    </quality_gate>
  </phase>
</phases>

<delegation_rules>
  <rule scope="design">ALL design → architect agent</rule>
  <rule scope="implementation">ALL implementation → developer agent</rule>
  <rule scope="review">ALL reviews → reviewer agent
