sdlc-3-implement

sdlc-3-implement is an agent for Claude Code from hackersandwizards/artificer. It costs 18 tokens per session (215 once invoked), scanned A, original, MIT.

A coding step that makes previously failing tests pass with the smallest correct change. Tests are checks that describe the expected behavior of the software.

In plain words
What is it for?
Use it after a planning and test-writing stage to implement a feature in a Next.js, Prisma, and Chakra codebase, then hand over a summary and list of changed files.
Why use it?
It gives the agent a precise target and limits unnecessary changes by following the existing code patterns.

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

sdlc-3-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 1mo 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

Make the failing tests from the previous stage pass with the minimum correct implementation.

  • Read the previous stage's plan and the failing tests to understand the exact behavior required.
  • Grep the Next.js, Prisma, and Chakra codebase for the existing conventions and patterns to follow.
  • Implement the feature with the minimum correct code, matching the codebase's existing conventions.
  • Output a summary of what was implemented plus the changed files as the handoff to the next stage.

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.
