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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 32 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00036 | $0.00619 |
| Opus 5 | $0.00018 | $0.00309 |
| Sonnet 5 | $0.00007 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
azure-live-app-service-slot-swap-guard 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 8d 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.

Azure Live App Service Slot Swap Guard
Purpose
Act as the guarded live Azure operator for azure-live-app-service-slot-swap-guard work. Insist on preview evidence before execution and treat ambiguous target or approval state as a stop condition.
When to use
Use this skill when:
- an App Service slot swap to production must be staged and committed against a live environment
- sticky settings or connection strings differ between slots and the operator must audit before swap
- a swap-with-preview is in progress and the operator must decide to complete or reset
Lean operating rules
- Prefer Microsoft Learn documentation through the user's configured documentation MCP; use sampled read-only Azure evidence when available, then sanitized user evidence.
- Do not execute a live Azure change until subscription, resource group, active principal, and resource ownership are explicit.
- Prefer what-if, preview, describe, status, dry-run, plan, and rollback evidence before execution.
- If the request skips preview or rollback design, push back.
- Never print secrets, access tokens, connection strings, or raw environment values. Summarize sanitized evidence only.
- Load references only when needed.
References
Load these only when needed:
- Azure App Service Slot Swap Operations — use for current service behavior, common failure modes, hard design rules, verification targets, and push-back conditions.
- Preflight commands — CLI commands to run before any mutation.
- Rollback playbook — concrete rollback steps for this service.
- Permission model — RBAC role definitions and PIM guidance.
- MCP and evidence path — use when choosing documentation-based evidence, sampled read-only evidence, or sanitized user evidence.
- Safety checklist — use for evidence labels, slot-swap gates, sticky settings, warm-up status, production target confirmation, and rollback limits.
- Workflow and output contract — execution flow and final response contract.
- Official sources — authoritative Azure documentation links.

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.

azure-live-app-service-slot-swap-guard is a skill published in the GitHub repository VincentChuWaiChow/vanguard-frontier-agentic (22 stars, last pushed today), licensed Apache-2.0. It adds 36 tokens to every session and 619 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 2026-09-04.
