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 5.1 | $0.00038 | $0.01061 |
| Opus 5.5 | $0.00015 | $0.00424 |
| Sonnet 5.5 | $0.00008 | $0.00212 |
| Haiku 4.5 | $0.00004 | $0.00106 |
Grade A, and why
verify-this 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 13d 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.
- **API behavior:** `curl <detected-api-url>` or a manual HTTP request. How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Verify This
If the current project has .claude/skills/verify-this/SKILL.md or .opencode/skills/verify-this/SKILL.md, read it and its references/; project specifics override this generic version.
Verification is not a recap. It proves or disproves a specific claim with repeatable evidence.
When To Use
- The user asks "verify this", "prove it works", "did this fix it", or "show me the evidence".
- A bug fix needs a before/after repro.
- A UI, CLI, API, performance, or memory claim needs measurement.
- A test passes but the user-visible behavior still needs confirmation.
Do not use this for vague claims like "the code is cleaner". Ask for a measurable claim first.
Workflow
- Restate the claim in falsifiable form: condition, metric, and threshold.
- Pick the smallest local surface that can disprove it.
- Capture a baseline from the old state: merge base, parent commit, failing branch, or current broken repro.
- Capture treatment from the changed state with the same command, data, warmup, and environment.
- Compare raw artifacts: numbers, screenshots, terminal transcripts, HTTP responses, profiles, heap snapshots, or test output.
- Return exactly one verdict:
VERIFIED,NOT VERIFIED, orINCONCLUSIVE.
Local Surfaces
Choose the smallest harness-native surface that isolates the claim. Detect the project stack from AGENTS.md, CLAUDE.md, and manifests, then select the appropriate surface:
TypeScript / Angular projects
- Code behavior: Focused unit/integration test, or a minimal repro script.
- Typecheck:
npx tsc --noEmit - Tests:
npm test -- <file-path>(Jest/Vitest pattern matching)
- Typecheck:
- UI behavior: Throwaway Playwright script under
/tmprun against the dev-server URL inangular.jsonorpackage.jsonscripts. Dispatch toe2e-runnerfor critical flows. Never commit ephemeral test scripts to the repo. - CLI/TUI behavior: Terminal transcript or demo recording showing stdin/stdout diff.
- API behavior:
curl <detected-api-url>or a manual HTTP request.
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.

verify-this is a skill published in the GitHub repository fmflurry/settings-opencode (171 stars, last pushed yesterday), licensed MIT. It adds 38 tokens to every session and 1,061 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-03.
