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 | $0.00334 |
| Opus 5 | $0.00000 | $0.00167 |
| Sonnet 5 | $0.00000 | $0.00067 |
| Haiku 4.5 | $0.00000 | $0.00033 |
Grade A, and why
get-default-access-controls-least-privilege 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
Default agent permission sets must exist in AL and stay least privilege
Description
IAgentFactory.GetDefaultAccessControls fills a temporary Access Control Buffer used when an instance is created. Permission sets that exist only as user-created sets in a sandbox are missing in the next environment. Granting D365 BUS FULL ACCESS or SUPER gives the agent a user-sized blast radius. Effective rights are still the intersection with the assigning user's permissions.
Best Practice
Insert only the permission sets the agent needs. For an AL permissionset object, use Scope::System and the ID of the app that defines it. Recreate permission sets that exist only as user-defined configuration in Business Central as AL objects first. Prefer a dedicated permission set over a full-user role.
See sample: get-default-access-controls-least-privilege.good.al.
Anti Pattern
Empty GetDefaultAccessControls, or inserting SUPER / D365 BUS FULL ACCESS because it made the demo work. Detection signal: Role ID on the default buffer that is a full-user role, or a set that is not in the app.
See sample: get-default-access-controls-least-privilege.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.

get-default-access-controls-least-privilege 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 334 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.
