agent-reproduce-feature

Use when reproducing an existing Codex or Claude Code feature in Qwen Code or another agent CLI by choosing a reference agent, capturing HTTP request bodies, prompts, tool/function schemas, terminal output, and then implementing the matching behavior in the target repo.

Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-engineered, highly actionable skill body: executable commands for every capture mode, a sequenced workflow with validation and error-recovery guidance, and clean separation into a real, one-level-deep reference file. The only weakness is mild redundancy between the Workflow and Capture Defaults sections.

DimensionReasoningScore

Conciseness

The body is lean and assumes competence — no concept explanations of what Codex, Claude Code, or mitmproxy are. Minor trimming is possible: the capture scripts are introduced in Workflow step 4 and then re-covered in Capture Defaults, and a few sentences ('Treat state diffs as sensitive local artifacts too...') restate adjacent rules.

4 / 5

Actionability

Commands are copy-paste ready: `command -v` discovery, mkdir output dirs, fully-argued invocations of run_with_mitm.sh, run_tmux_capture.sh, and capture_state.py snapshot/diff, plus a JSON recording template. Common cases (codex headless, claude-code tmux, interactive TUI) each get a concrete example.

5 / 5

Workflow Clarity

The 8-step Workflow is clearly sequenced from feature definition through capture, fact extraction, implementation, testing, and handoff. Validation is explicit (step 7 tests/smoke command, Done Criteria checklist), and error recovery is present ('If TLS fails, read the certificate notes... and fix trust before interpreting missing traffic as product behavior').

5 / 5

Progressive Disclosure

The SKILL.md stays an overview and delegates depth to a clearly signaled, one-level-deep reference ('Read references/capture-workflow.md before running capture for the first time'), which exists and does not nest further. All referenced bundle files exist; llm_dump.py is an internal helper invoked by run_with_mitm.sh rather than an orphan.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concrete, comprehensive action list paired with an explicit and specific 'Use when' trigger. Only minor upside remains in adding synonyms like 'port' or 'replicate' for broader trigger coverage.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'choosing a reference agent, capturing HTTP request bodies, prompts, tool/function schemas, terminal output, and then implementing the matching behavior' — covering the full capability surface. This matches the anchor for comprehensive, specific concrete actions; nothing is vague or generic.

5 / 5

Completeness

It explicitly answers both questions: the 'what' is choosing a reference agent, capturing request bodies/prompts/schemas/terminal output, and implementing matching behavior; the 'when' is an explicit 'Use when reproducing an existing Codex or Claude Code feature in Qwen Code or another agent CLI' trigger clause. This matches the 5 anchor clearly.

5 / 5

Trigger Term Quality

Good keyword coverage with the natural product names users would say ('reproducing', 'Codex', 'Claude Code', 'Qwen Code', 'agent CLI') plus artifact terms like 'HTTP request bodies' and 'tool/function schemas'. It falls just short of the 5 anchor because common synonyms such as 'port', 'replicate', 'match', or 'parity' are absent.

4 / 5

Distinctiveness Conflict Risk

The niche is highly specific — reproducing Codex/Claude Code features in Qwen Code via capture-based analysis — with distinct triggers that no general-purpose skill would claim. Conflict risk is minimal.
