Agent Development
Build reliable Claude Code agents
Plugin agents can trigger poorly or receive excessive tool access. This skill provides templates and guidance for focused agents with clear behavior.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "Agent Development" from https://skillstore.io/skills/agent-development.md and its manifest at https://skillstore.io/api/skills/agent-development/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Agent-readable resources
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Test it
Using "Agent Development". Create an agent that checks API documentation for missing examples.
Expected outcome:
- A specific agent name and trigger description.
- Read-only tool recommendations.
- A system prompt with review steps and a report format.
Using "Agent Development". Which tools should a test-planning agent receive?
Expected outcome:
- A least-privilege recommendation for reading files and searching code.
- An explanation of when a shell tool is unnecessary.
Security Audit
SafeAll 82 static findings are false positives from Markdown backticks, instructional prose, or the local validator shell syntax. The validator parses a supplied file with quoted values and does not evaluate its contents. No prompt injection, data exfiltration, or malicious intent was found in the reviewed materials.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Create a first plugin agent
Build a focused agent file with required frontmatter and a structured prompt.
Improve agent triggering
Add concrete descriptions and examples so the correct agent is selected for user requests.
Review agent permissions
Choose the smallest practical tool set for analysis, generation, or testing work.
Try These Prompts
Help me create a Claude Code agent that reviews TypeScript files. Include a name, triggering description, focused tools, and a short system prompt.
Improve this agent description with three concrete triggering examples. Explain when the agent should not run: [paste description].
Recommend the minimum Claude Code tools for an agent that analyzes code and reports findings without editing files. Explain each choice.
Design a plugin agent for [domain]. Define boundaries, a repeatable process, edge cases, output expectations, and safe tool permissions.
Best Practices
- Use specific triggering conditions and several realistic examples.
- Grant only the tools required for the agent task.
- Define responsibilities, process steps, edge cases, and output expectations.
Avoid
- Do not use vague descriptions that overlap with unrelated agents.
- Do not grant full tool access when read-only tools are sufficient.
- Do not omit testing for triggering behavior and edge cases.
