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 | $0.00024 | $0.00404 |
| Opus 5 | $0.00012 | $0.00202 |
| Sonnet 5 | $0.00005 | $0.00081 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
update-or-delete-tests-that-assert-intentionally-removed-behavio 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 8d 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
update or delete tests that assert intentionally removed behavior
Trigger
- (no explicit trigger metadata; cluster derived from category/tags)
Required Procedure
- update or delete tests that assert intentionally removed behavior
- verify no test asserts behavior the changeset deliberately removes
Forbidden Shortcuts
- (none recorded)
Delegation Template
When delegating a task affected by this skill, include:
SKILLS: file:.opencode/skills/generated/update-or-delete-tests-that-assert-intentionally-removed-behavio/SKILL.md
Reviewer Checks
- grep test files for removed code patterns (e.g. Date.now() timestamps, deprecated API calls)
- run full test suite after changes and classify every failure as regression vs stale-test
Test Engineer Checks
- Add or update tests covering the trigger condition and the forbidden shortcut.
Source Knowledge IDs
- ca60f911-c1d4-4fb1-8245-44bf6cf95045 — When intentionally removing a code path, update or delete all tests asserting the old behavior in the same changeset — stale assertions that validate removed behavior count as test failures, not expected regressions.
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.

update-or-delete-tests-that-assert-intentionally-removed-behavio is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (466 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 404 once invoked, about $0.0001 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.
