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 | $0.00038 | $0.00348 |
| Opus 5 | $0.00019 | $0.00174 |
| Sonnet 5 | $0.00008 | $0.00070 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
integration-e2e-testing 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 2d 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
Integration and E2E Test Implementation and Review Rules
Implementation Rules
Behavior Verification
| Step Type | Verification Target |
|---|---|
| Trigger | Reproduce in test setup (Arrange) |
| Process | Intermediate state or function call |
| Observable Result | Final output value (return value, error message, log output) |
Pass Criteria: Test passes if "observable result" is verified as return value or mock call argument
Integration Test Mock Boundaries
| Judgment Criteria | Mock | Actual |
|---|---|---|
| Part of test target? | No → Can mock | Yes → Actual required |
| External network communication? | Yes → Mock required | No → Actual recommended |
E2E Test Execution Conditions
- Execute only after all components are implemented
- Do not use mocks (full system integration required)
Review Criteria
Skeleton and Implementation Consistency
| Check | Failure Condition |
|---|---|
| Behavior Verification | No assertion for "observable result" |
| Verification Item Coverage | Listed verification items not included in assertions |
| Mock Boundary | Internal components mocked in integration test |
Implementation Quality
| Check | Failure Condition |
|---|---|
| AAA Structure | Arrange/Act/Assert separation unclear |
| Independence | State sharing between tests, execution order dependency |
| Reproducibility | Depends on date/random, results vary |
| Readability | Test name and verification content don't match |
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.

integration-e2e-testing is a skill published in the GitHub repository shinpr/agentic-code (49 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 348 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 2026-08-30.
