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 | $0.00048 | $0.00923 |
| Opus 5.5 | $0.00019 | $0.00369 |
| Sonnet 5.5 | $0.00010 | $0.00185 |
| Haiku 4.5 | $0.00005 | $0.00092 |
Grade A, and why
custom-connectors 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 2mo 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: Custom Connectors
When to Use
Trigger when building, configuring, or debugging custom connectors — reusable API wrappers that expose REST APIs as Power Platform connectors for use in Power Automate, Power Apps, and Copilot Studio.
When to Use Custom Connectors vs Alternatives
| Scenario | Use | Why |
|---|---|---|
| Standard connector exists | Standard connector | Zero maintenance, Microsoft-supported |
| REST API used in one flow only | HTTP action in Power Automate | Simpler, no connector overhead |
| REST API used across multiple flows/apps | Custom connector | Reusable, typed, discoverable |
| REST API with complex auth (OAuth 2.0) | Custom connector | Auth handled once, shared across all uses |
| High-volume API calls needing throttling | Custom connector + Azure APIM | APIM handles rate limiting, caching, monitoring |
| On-premises API (no public endpoint) | Custom connector + On-premises Data Gateway | Gateway bridges private network |

⚠️ REQUIRED: Load Sub-Files Before Implementation
SKILL.md is a summary only — it is NOT sufficient for implementation.
The detailed content (complete payloads, XML templates, working examples, edge-case handling) lives in sub-files in the same directory as this SKILL.md. Before writing any code, you MUST use read_file on the sub-files relevant to your task:
- OpenAPI Definition — Swagger structure, action definitions, schema definitions, x-ms extensions, dynamic values/schema
- Authentication — API Key, OAuth 2.0 (Authorization Code), Azure AD / Entra ID, apiProperties.json configuration
- Triggers — Polling triggers (batch), webhook triggers, deregistration endpoint, trigger hints
- Policies & APIM — Connector policies (set header, route request), Azure APIM integration, DLP classification, CLI workflow, solution-aware connectors
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

custom-connectors is a skill published in the GitHub repository korchard333/claude-power-platform-community (50 stars, last pushed 6mo ago), licensed MIT. It adds 48 tokens to every session and 923 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.
