cmd_feature_dev

cmd_feature_dev is a skill for Claude Code from majiang213/OpenClaw-MAS. It costs 19 tokens per session (512 once invoked), scanned A, original, MIT.

A guided workflow for adding a feature to an existing code project, from understanding the request and codebase through implementation and review.

In plain words
What is it for?
Use it to explore a project, design a solution, implement a feature, and review the result.
Why use it?
It reduces the risk of changing the wrong part of a project or overlooking important requirements before coding.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cmd_feature_dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Project Path

The first argument is the project path. Before doing anything else:

  1. Extract the project path from the first argument
  2. Verify the path exists
  3. Work within that directory for all file operations and shell commands

Feature Development

A structured feature-development workflow that emphasizes understanding existing code before writing new code.

Phases

1. Discovery

  • Read the feature request carefully
  • Identify requirements, constraints, and acceptance criteria
  • Ask clarifying questions if the request is ambiguous

2. Codebase Exploration

Delegate to the code-explorer agent:

Include in the task payload:

  • Project path
  • The feature or area to explore
  • Relevant files or modules if known

First, reply to the user briefly, then call sessions_spawn:

{
  "agentId": "code-explorer",
  "sessionKey": "code-explorer",
  "task": "<project path and exploration request>",
  "runTimeoutSeconds": 0
}

3. Clarifying Questions

  • Present findings from exploration
  • Ask targeted design and edge-case questions
  • Wait for user response before proceeding

4. Architecture Design

Delegate to the code-architect agent:

Include in the task payload:

  • Project path
  • Feature request and exploration findings
  • Any constraints or preferences
{
  "agentId": "code-architect",
  "sessionKey": "code-architect",
  "task": "<project path, feature request, and exploration findings>",
  "runTimeoutSeconds": 0
}

Wait for approval before implementing.

5. Implementation

  • Implement the feature following the approved design
  • Prefer TDD where appropriate
  • Keep commits small and focused

6. Quality Review

Delegate to the code-reviewer agent:

{
  "agentId": "code-reviewer",
  "sessionKey": "code-reviewer",
  "task": "<project path and review request>",
  "runTimeoutSeconds": 0
}

7. Summary

  • Summarize what was built
  • List follow-up items or limitations
  • Provide testing instructions
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
