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 | $0.00060 | $0.02616 |
| Opus 5.5 | $0.00024 | $0.01046 |
| Sonnet 5.5 | $0.00012 | $0.00523 |
| Haiku 4.5 | $0.00006 | $0.00262 |
Grade A, and why
mitigate-breaking-changes 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 23d 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.

Skill: mitigate-breaking-changes
Patterns and techniques for mitigating breaking changes when regenerating Azure management-plane .NET SDKs. Use these to preserve backward compatibility in the generated SDK surface.
When Invoked
Trigger phrases: "mitigate breaking changes", "fix breaking change", "customization patterns", "how to keep backward compat", "CodeGenType", "CodeGenSuppress", "markAsPageable", "hierarchyBuilding", "base type change".
Common breaking-change workflow
When invoked from azsdk-common-sdk-breaking-change, use the
.NET pattern catalog and the original
azsdk_package_detect_breaking_change result. Preserve the ApiCompat diagnostics,
previous signatures, additions, and originBreaks; a removal/addition pair is
not proof of a rename.
- For a user-selected
mitigation: generatorchange, verify the documented preconditions and matching previous contract. Reuse the management generator's existing conditional-header and model-factory compatibility overload support. Regenerate; do not write a second synthesizer or patch generated files. - For
mitigation: client customization, useazsdk_customized_code_updatewith the user's selected change and permitted edit scope.CustomCodecannot edit TypeSpec inputs or change the pinned spec commit;SpecChangeRequiredrequires a spec-owner handoff, not an automatic retry with broader scope. - For
mitigation: manual, missing evidence, or unsupported generator output, explain the decision needed and stop automatic mitigation.
This skill's ARM patterns are management-specific. Do not apply resource hierarchy, ARM identifier, or conditional-header transformations to data-plane libraries without separately verified support.
After a change, regenerate and compile fresh artifacts as needed, rerun the standalone detector, then run ordinary builds, analyzers, and tests separately. Do not treat a missing GA baseline, stale artifact, or detector failure as a compatibility pass. Never add suppressions without explicit owner approval.
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.

mitigate-breaking-changes is a skill published in the GitHub repository Azure/azure-sdk-for-net (6,074 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 2,616 once invoked, about $0.0002 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 2026-08-30.
