# Send Agent Development to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

### Agent Development for Claude Code

Build effective custom agents for Claude Code with proper delegation, tool access, and prompt design.

### Agent Description Pattern

The description field determines whether Claude will automatically delegate tasks.

### Strong Trigger Pattern

---
name: agent-name
description: |
  [Role] specialist. MUST BE USED when [specific triggers].
  Use PROACTIVELY for [task category].
  Keywords: [trigger words]
tools: Read, Write, Edit, Glob, Grep, Bash
model: sonnet
---

### Weak vs Strong Descriptions

Weak (won't auto-delegate)Strong (auto-delegates)"Analyzes screenshots for issues""Visual QA specialist. MUST BE USED when analyzing screenshots. Use PROACTIVELY for visual QA.""Runs Playwright scripts""Playwright specialist. MUST BE USED when running Playwright scripts. Use PROACTIVELY for browser automation."

Key phrases:

"MUST BE USED when..."
"Use PROACTIVELY for..."
Include trigger keywords

### Delegation Mechanisms

Explicit: Task tool subagent_type: "agent-name" - always works
Automatic: Claude matches task to agent description - requires strong phrasing

Session restart required after creating/modifying agents.

### Tool Access Principle

If an agent doesn't need Bash, don't give it Bash.

Agent needs to...Give toolsDon't giveCreate files onlyRead, Write, Edit, Glob, GrepBashRun scripts/CLIsRead, Write, Edit, Glob, Grep, Bash—Read/audit onlyRead, Glob, GrepWrite, Edit, Bash

Why? Models default to cat > file << 'EOF' heredocs instead of Write tool. Each bash command requires approval, causing dozens of prompts per agent run.

### Allowlist Pattern

Instead of restricting Bash, allowlist safe commands in .claude/settings.json:

{
  "permissions": {
    "allow": [
      "Write", "Edit", "WebFetch(domain:*)",
      "Bash(cd *)", "Bash(cp *)", "Bash(mkdir *)", "Bash(ls *)",
      "Bash(cat *)", "Bash(head *)", "Bash(tail *)", "Bash(grep *)",
      "Bash(diff *)", "Bash(mv *)", "Bash(touch *)", "Bash(file *)"
    ]
  }
}

### Model Selection (Quality First)

Don't downgrade quality to work around issues - fix root causes instead.

ModelUse ForOpusCreative work (page building, design, content) - quality mattersSonnetMost agents - content, code, research (default)HaikuOnly script runners where quality doesn't matter

### Root Cause Fix (REQUIRED)

Add to ~/.bashrc or ~/.zshrc:

export NODE_OPTIONS="--max-old-space-size=16384"

Increases Node.js heap from 4GB to 16GB.

### Parallel Limits (Even With Fix)

Agent TypeMax ParallelNotesAny agents2-3Context accumulates; batch then pauseHeavy creative (Opus)1-2Uses more memory

### Recovery

source ~/.bashrc or restart terminal
NODE_OPTIONS="--max-old-space-size=16384" claude
Check what files exist, continue from there

### Sub-Agent vs Remote API

Always prefer Task sub-agents over remote API calls.

AspectRemote API CallTask Sub-AgentTool accessNoneFull (Read, Grep, Write, Bash)File readingMust pass all content in promptCan read files iterativelyCross-referencingSingle context windowCan reason across documentsDecision qualityGeneric suggestionsSpecific decisions with rationaleOutput quality~100 lines typical600+ lines with specifics

// ❌ WRONG - Remote API call
const response = await fetch('https://api.anthropic.com/v1/messages', {...})

// ✅ CORRECT - Use Task tool
// Invoke Task with subagent_type: "general-purpose"

### Declarative Over Imperative

Describe what to accomplish, not how to use tools.

### Wrong (Imperative)

### Check for placeholders
\`\`\`bash
grep -r "PLACEHOLDER:" build/*.html

### Right (Declarative)

\`\`\`markdown
### Check for placeholders
Search all HTML files in build/ for:
- PLACEHOLDER: comments
- TODO or TBD markers
- Template brackets like [Client Name]

Any match = incomplete content.

### What to Include

IncludeSkipTask goal and contextExplicit bash/tool commandsInput file paths"Use X tool to..."Output file paths and formatStep-by-step tool invocationsSuccess/failure criteriaShell pipeline syntaxBlocking checks (prerequisites)Micromanaged workflowsQuality checklists

### Self-Documentation Principle

"Agents that won't have your context must be able to reproduce the behaviour independently."

Every improvement must be encoded into the agent's prompt, not left as implicit knowledge.

### What to Encode

DiscoveryWhere to CaptureBug fix patternAgent's "Corrections" or "Common Issues" sectionQuality requirementAgent's "Quality Checklist" sectionFile path conventionAgent's "Output" sectionTool usage patternAgent's "Process" sectionBlocking prerequisiteAgent's "Blocking Check" section

### Test: Would a Fresh Agent Succeed?

Before completing any agent improvement:

Read the agent prompt as if you have no context
Ask: Could a new session follow this and produce the same quality?
If no: Add missing instructions, patterns, or references

### Anti-Patterns

Anti-PatternWhy It Fails"As we discussed earlier..."No prior context existsRelying on files read during devAgent may not read same filesAssuming knowledge from errorsAgent won't see your debugging"Just like the home page"Agent hasn't built home page

### Agent Prompt Structure

Effective agent prompts include:

## Your Role
[What the agent does]

## Blocking Check
[Prerequisites that must exist]

## Input
[What files to read]

## Process
[Step-by-step with encoded learnings]

## Output
[Exact file paths and formats]

## Quality Checklist
[Verification steps including learned gotchas]

## Common Issues
[Patterns discovered during development]

### Pipeline Agents

When inserting a new agent into a numbered pipeline (e.g., HTML-01 → HTML-05 → HTML-11):

Must UpdateWhatNew agent"Workflow Position" diagram + "Next" fieldPredecessor agentIts "Next" field to point to new agent

Common bug: New agent is "orphaned" because predecessor still points to old next agent.

Verification:

grep -n "Next:.*→\\|Then.*runs next" .claude/agents/*.md

### The Sweet Spot

Best use case: Tasks that are repetitive but require judgment.

Example: Auditing 70 skills manually = tedious. But each audit needs intelligence (check docs, compare versions, decide what to fix). Perfect for parallel agents with clear instructions.

Not good for:

Simple tasks (just do them)
Highly creative tasks (need human direction)
Tasks requiring cross-file coordination (agents work independently)

### Effective Prompt Template

For each [item]:
1. Read [source file]
2. Verify with [external check - npm view, API call, etc.]
3. Check [authoritative source]
4. Score/evaluate
5. FIX issues found ← Critical instruction

Key elements:

"FIX issues found" - Without this, agents only report. With it, they take action.
Exact file paths - Prevents ambiguity
Output format template - Ensures consistent, parseable reports
Batch size ~5 items - Enough work to be efficient, not so much that failures cascade

### Workflow Pattern

1. ME: Launch 2-3 parallel agents with identical prompt, different item lists
2. AGENTS: Work in parallel (read → verify → check → edit → report)
3. AGENTS: Return structured reports (score, status, fixes applied, files modified)
4. ME: Review changes (git status, spot-check diffs)
5. ME: Commit in batches with meaningful changelog
6. ME: Push and update progress tracking

Why agents don't commit: Allows human review, batching, and clean commit history.

### Signs a Task Fits This Pattern

Good fit:

Same steps repeated for many items
Each item requires judgment (not just transformation)
Items are independent (no cross-item dependencies)
Clear success criteria (score, pass/fail, etc.)
Authoritative source exists to verify against

Bad fit:

Items depend on each other's results
Requires creative/subjective decisions
Single complex task (use regular agent instead)
Needs human input mid-process

### Agent Frontmatter Template

---
name: my-agent
description: |
  [Role] specialist. MUST BE USED when [triggers].
  Use PROACTIVELY for [task category].
  Keywords: [trigger words]
tools: Read, Write, Edit, Glob, Grep, Bash
model: sonnet
---

### Fix Bash Approval Spam

Remove Bash from tools if not needed
Put critical instructions FIRST (right after frontmatter)
Use allowlists in .claude/settings.json

### Memory Crash Recovery

export NODE_OPTIONS="--max-old-space-size=16384"
source ~/.bashrc && claude
