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 | $0.00253 |
| Opus 5 | $0.00000 | $0.00127 |
| Sonnet 5 | $0.00000 | $0.00051 |
| Haiku 4.5 | $0.00000 | $0.00025 |
Grade A, and why
bind-agent-subscribers-only-in-agent-session 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
Bind extra agent subscribers only inside an agent session
Description
Page-filter tweaks, extra validation, and prompt dialogs for the agent should not run for every user. Agent Session.IsAgentSession distinguishes agent UI sessions. Binding those subscribers on System Initialization only when the session is an agent session avoids global subscriber cost. Models register SingleInstance table subscribers unconditionally.
Best Practice
On OnAfterInitialization, exit unless Agent Session.IsAgentSession. Then BindSubscription a single-instance codeunit that holds the current task id. Keep those subscribers internal.
See sample: bind-agent-subscribers-only-in-agent-session.good.al.
Anti Pattern
Event subscribers on Sales Header OnAfterInsert that always Message the agent, with no IsAgentSession guard. Detection signal: agent-only behaviour in a static subscriber that is not bind-gated.
See sample: bind-agent-subscribers-only-in-agent-session.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.

bind-agent-subscribers-only-in-agent-session 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 253 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.
