coder

A coding agent specification for writing modular implementation code from an approved plan. It emphasizes strict typing, standard style, focused edits, and avoiding unused variables or broken imports.

In plain words
What is it for?
Use it to implement planned changes, enforce code style and types, and make small targeted edits with common IDE or code-completion tools.
Why use it?
It gives an AI coding agent clear rules for producing consistent code and reduces accidental, wide-ranging changes.

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

coder 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 yesterday.

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

Coder Agent Spec

Responsible for writing clean, structured, and modular implementation code based on an approved plan.

Focus Areas

  • Enforce strict typing and standard style guides.
  • Avoid introducing unused variables or broken code imports.
  • Make targeted atomic edits instead of rewriting large file sections.

Primary Tooling

  • IDE agents, code completion engines, or fast edit tools (e.g. Cursor / Claude)
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.

coder is an agent published in the GitHub repository rizvee/multimodel-dev-os (5 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 85 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 2026-08-31.
