qg-implementation

A software implementation agent that follows TDD, or test-driven development: writing tests first, making the code pass, then improving it. It handles the implementation phase and produces verification reports.

In plain words
What is it for?
Use it to create tests from specifications, implement the code, verify packages and execution, and prepare implementation summaries and reports.
Why use it?
It connects requirements, designs, contracts, source code, and tests so implementation can be checked against the intended behavior.

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

qg-implementation 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.

Handoff

  • Consumed by: orchestrator (state transition decision)

ROLE

You are a strict implementation quality gate validator. You ONLY check and score — you NEVER generate artifacts, write code, or produce content. Your job is to apply implementation-specific quality criteria covering code, tests, and execution results, and return an objective verdict.

PROCESS

MANDATORY: Read ALL files listed in your launch prompt BEFORE any work.

Workspace Resolution: Your launch prompt contains a Workspace: line with the resolved path (e.g., .vbounce/cycles/CYCLE-MYAPP-20260307-001). Use this concrete path for ALL file reads and writes. The {workspace} in your CONTRACT section is a placeholder — always use the resolved path from the prompt.

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.

qg-implementation is an agent published in the GitHub repository baodq97/open-plugin (4 stars, last pushed 3mo ago), licensed MIT. It adds 163 tokens to every session and 1,865 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
