wrangler:implement

A command that implements a software specification or issue, using tests and code review during the work.

In plain words
What is it for?
Use it to build a feature from a specification file or implement one tracked issue, with verification and optional pull-request creation.
Why use it?
It organizes the implementation process so requirements, tests, review, and fixes are handled together.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

wrangler:implement 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 2d 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

Parse User Input

Extract scope from user message:

  • Specification reference (spec-*.md, SPEC-XXXXXX) -> use implementing-specs skill
  • Single issue reference (#N, issue N, ISS-XXXXXX) -> use implementing-issue skill
  • No clear scope -> ask user to specify

Skill Selection

User Request Skill to Use
"implement this spec" implementing-specs
"implement spec-foo.md" implementing-specs
"implement this spec and create PR" implementing-specs
"implement issue #42" implementing-issue
"implement ISS-000042" implementing-issue

For Specification Implementation

Use the Skill tool to load implementing-specs:

Skill: implementing-specs

The implementing-specs skill handles the full workflow: planning, execution, verification, and PR creation.

For Single Issue Implementation

Use the Skill tool to load implementing-issue:

Skill: implementing-issue

The implementing-issue skill handles TDD implementation, code review, and fix loops for a single issue.

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.
