test-file-split SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
test-file-split from zaxbyhub/opencode-swarm is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add zaxbyhub/opencode-swarm/test-file-split@git:20261030.5c7ee45Pins git:20261030.5c7ee45 in mdr.lock. Pin the fingerprint instead.

Protocol for splitting test files that approach or exceed the FR-006 500-line limit (enforced in CI by scripts/check-test-file-cap.ts as a diff-scoped ratchet). Covers describe-block extraction, shared helper management, pure-function extraction, mock isolation verification, and cascading-split detection. Load when a test file approaches or exceeds 500 lines.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Test File Split Protocol (FR-006)
`scripts/check-test-file-cap.ts` enforces the **500-line cap** per test file (FR-006 / SC-006.1) as a **diff-scoped ratchet**: new test files over 500 lines and existing over-cap files that grew fail the quality gate and block PR merge. Pre-existing over-cap files not touched by the PR are non-blocking. Escape hatch: `TEST_CAP_ENFORCE=0` soft-warns. This skill covers the complete splitting protocol.
Read first: `.opencode/skills/writing-tests/SKILL.md` (or `.claude/skills/writing-tests/SKILL.md`) for bun:test framework rules, mock isolation patterns, and file placement conventions.
## When to use this skill
- A test file exceeds or approaches 500 lines
- CI fails with an FR-006 file-size violation
- You are adding tests to a file that is already above 400 lines (proactive split)
## Step 1 — Measure and identify split boundaries
```bash
# Check the file
wc -l tests/unit/scripts/my-module.test.ts
# Find all test files exceeding 400 lines (early warning)
find tests/ -name "*.test.ts" -exec wc -l {} \; | sort -rn | awk '$1 > 400'
```
Identify natural `describe()` block boundaries. Group blocks by functional area:

How to install
mdr add zaxbyhub/opencode-swarm/test-file-split@sha256:750d7846f7ad6f90The line at the top of this page pins the label git:20261030.5c7ee45, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
