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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00469 |
| Opus 5 | $0.00014 | $0.00234 |
| Sonnet 5 | $0.00005 | $0.00094 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
use-internals-di-seam-pattern-for-test-injectable-functions 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 7d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
- 8a374ec6-734e-4b34-9119-1b6148db3a1e — In Bun's shared test-runner process, mock.module() leaks across test files. Always use _internals DI seams or spread-real-exports for node:fs/child_process mocks instead of bare m What it actually says
use _internals DI seam pattern for test-injectable functions
Trigger
- (no explicit trigger metadata; cluster derived from category/tags)
Required Procedure
- use _internals DI seam pattern for test-injectable functions
- spread real module exports when mocking node built-ins (import * as real from 'node:module'; mock.module('node:module', () => ({ ...real, targetFn: mockFn })))
- verify mock isolation by running test files in combined mode, not individually
Forbidden Shortcuts
- rely on mock.module() isolation between test files in bun:test
- declare a test passing based solely on individual file execution

Reviewer Checks
- Verify each required action above appears in the diff.
Test Engineer Checks
- Add or update tests covering the trigger condition and the forbidden shortcut.

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.

use-internals-di-seam-pattern-for-test-injectable-functions is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (466 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 469 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
