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 | $0.00000 | $0.00311 |
| Opus 5 | $0.00000 | $0.00156 |
| Sonnet 5 | $0.00000 | $0.00062 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
register-copilot-capability-for-the-agent 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 yesterday.
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
Register a Copilot capability for the agent on install
Description
Each agent type needs a Copilot Capability enum value that the factory links as the feature switch and billing surface. The capability is invisible on Copilot and agent capabilities until an install codeunit calls RegisterCapability when it is not already registered. Unique ordinals matter across installed apps. Models often extend Agent Metadata Provider and never register the capability.
Best Practice
Extend Copilot Capability with a unique value. In OnInstallAppPerDatabase, call Copilot Capability.IsCapabilityRegistered and, if false, RegisterCapability with availability, billing type, and a learn-more URL. Point IAgentFactory at that capability.
See sample: register-copilot-capability-for-the-agent.good.al.
Anti Pattern
Shipping the agent enum without a Copilot Capability value, or adding the enum but never calling RegisterCapability. Duplicate ordinals across extensions also collide. Detection signal: agent metadata provider with no matching capability registration in an install codeunit.
See sample: register-copilot-capability-for-the-agent.bad.al.

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.

register-copilot-capability-for-the-agent is an agent published in the GitHub repository microsoft/BCQuality (204 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 311 tokens. 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.
