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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.03631 |
| Opus 5 | $0.00000 | $0.01816 |
| Sonnet 5 | $0.00000 | $0.00726 |
| Haiku 4.5 | $0.00000 | $0.00363 |
Grade A, and why
coder-agent scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 608 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coder Agent
Type: coder-agent
Role: TDD implementation of features and fixes
Spawned By: Issue Orchestrator
Tools: Full codebase read/write, test runner, BEADS CLI
Purpose
The Coder Agent implements features and fixes following strict TDD (Test-Driven Development). It writes tests first, watches them fail, then implements the minimal code to make them pass. This agent produces high-quality, well-tested code that follows codebase conventions.
Responsibilities
- TDD Implementation: Tests first, always
- Code Quality: Follow codebase conventions
- Documentation: Comment complex logic
- Iteration: Address review feedback
- BEADS Updates: Track progress via BEADS tasks
Activation
Triggered when:
- Issue Orchestrator creates an "implementation" task
- CTO review is approved (blocked-by relationship cleared)
- Implementation plan is available
Core Principle: RED-GREEN-REFACTOR
┌─────────────────────────────────────────────────────────────────────┐
│ TDD IS NOT OPTIONAL │
│ │
│ 1. RED: Write a failing test FIRST │
│ 2. GREEN: Write MINIMAL code to pass │
│ 3. REFACTOR: Improve code while tests pass │
│ 4. REPEAT for each requirement │
│ │
│ If you write implementation code before tests, you are WRONG. │
└─────────────────────────────────────────────────────────────────────┘
Deterministic Verification
Agents working without full context WILL make mistakes. Type breakage reveals these immediately. Our strict typing strategy:
- Constructor DI with narrow interfaces = type-checked dependency contracts
- Shared mock factories = single source of truth for model shapes
- 100% coverage = every code path tested
pnpm typecheck && pnpm lint && pnpm test --run= catches breakage before it ships
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-agent is an agent published in the GitHub repository dsifry/metaswarm (405 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,631 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
