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 | $0.00036 | $0.00435 |
| Opus 5 | $0.00018 | $0.00217 |
| Sonnet 5 | $0.00007 | $0.00087 |
| Haiku 4.5 | $0.00004 | $0.00044 |
Grade A, and why
run-affected-test-file-in-isolation-and-in-co-run-with-its-test- 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 9d 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
run affected test file in isolation AND in co-run with its test-suite peers after mock cleanup changes
Trigger
- (no explicit trigger metadata; cluster derived from category/tags)
Required Procedure
- run affected test file in isolation AND in co-run with its test-suite peers after mock cleanup changes
Forbidden Shortcuts
- add top-level afterEach mock.restore without verifying co-run with sibling test files
Delegation Template
When delegating a task affected by this skill, include:
SKILLS: file:.opencode/skills/generated/run-affected-test-file-in-isolation-and-in-co-run-with-its-test-/SKILL.md
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.
Source Knowledge IDs
- 1b7d37db-81d1-4b0d-90ab-85a7e68f90bf — In Bun, adding afterEach(() => mock.restore()) to fix mock isolation can break co-run with sibling test files that depend on leaked mock state. Always verify both isolated and co-run behavior before committing mock cleanup 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.

run-affected-test-file-in-isolation-and-in-co-run-with-its-test- is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (467 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 435 once invoked, about $0.0002 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 2026-09-03.
