implement

An implementation procedure for carrying out a feature or fix described in a specification document.

In plain words
What is it for?
Reading requirements, creating a task list, implementing each item, running sanity checks, and marking the specification complete.
Why use it?
It turns a written plan into tracked coding tasks and includes checks that the finished work meets the specification.

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.

Made for: Codex.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 142 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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

You are tasked with implementing a feature/fix based on a provided spec sheet.

Follow the implementation process below systematically.

Implementation Process

  1. Read and analyze the spec: Understand the problem, solution, and all implementation tasks
  2. Plan with todos: Use todo_write to create a comprehensive todo list from the spec's checkbox items
  3. Implement systematically: Work through each todo item in logical order, marking them as in-progress and completed
  4. Quality assurance: Complete the Sanity Check section tasks as specified in the spec
  5. Verify completion: Ensure all spec requirements are met and update the spec to mark all todos as done

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.

implement is a command published in the GitHub repository saffron-health/opencode-gui (57 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 142 tokens. 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 2026-08-30.
