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 | $0.00030 | $0.00554 |
| Opus 5.5 | $0.00012 | $0.00222 |
| Sonnet 5.5 | $0.00006 | $0.00111 |
| Haiku 4.5 | $0.00003 | $0.00055 |
Grade A, and why
stress-test-validity-envelope-mapping 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 1mo 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.

Validity Envelope Mapping
Tactics
- boundary-probing
- contradiction-derivation
Method
- Identify all dimensions where claim validity may vary
- For each dimension, probe from center outward to find boundaries
- Record transition points (valid -> invalid)
- Construct multi-dimensional validity envelope
- Identify the weakest dimensions (narrowest valid range)
- Report envelope with confidence levels per boundary
Budget
| Size | Envelope dimensions | Probes per dimension | Resolution |
|---|---|---|---|
| S | 2 | 5 | Coarse |
| M | 4 | 8 | Medium |
| L | 6 | 12 | Fine |

Available Tactics
Optional, no fixed order; the final leaf is always a sop.
| Tactic | When to use |
|---|---|
| boundary-probing | Map parameter space, generate extreme values, test at boundaries, detect breakpoints, synthesize validity envelope. |
| contradiction-derivation | Negate a claim, derive logical consequences step by step, detect whether a genuine contradiction or absurdity emerges. |
Available SOPs
Optional, no fixed order; the final leaf is always a sop.
| SOP | When to use |
|---|---|
| breakpoint-detection | Test a claim at extreme parameter values and detect the precise point where it breaks down. |
| extreme-value-generation | Generate boundary and extreme test values for a given parameter dimension to stress-test claims. |
| parameter-space-mapping | Identify all parameter dimensions along which a claim's validity might vary. |
| stress-test-validity-envelope-construction | Synthesize breakpoints across dimensions into a coherent validity envelope for a claim. |
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.

stress-test-validity-envelope-mapping is a skill published in the GitHub repository yogsoth-ai/stress-test (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 554 once invoked, about $0.0001 per session on Opus 5.5. 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.
