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 | $0.00026 | $0.00181 |
| Opus 5 | $0.00013 | $0.00090 |
| Sonnet 5 | $0.00005 | $0.00036 |
| Haiku 4.5 | $0.00003 | $0.00018 |
Grade A, and why
Application credential hygiene 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 10d 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
Application credential hygiene
- Resolve both the application registration and corresponding service principal when present.
- Inventory secrets and certificates with expiration, owner coverage, and sign-in audience.
- Separate delegated permissions from application permissions and flag high-impact Graph application roles.
- Identify ownerless applications and credentials that are expired or approaching expiry.
- Treat Microsoft-managed and managed-identity service principals according to platform ownership rules.
- State whether evidence came from live Graph, cache, or a capped inventory.
- Recommend rotation, owner assignment, permission reduction, and workload validation; never delete or rotate credentials without an explicit approved write.
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.

Application credential hygiene is a skill published in the GitHub repository zmustafa/AzureSupportAgent (45 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 181 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 2026-08-30.
