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.

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 | $0.00084 | $0.03755 |
| Opus 5.5 | $0.00034 | $0.01502 |
| Sonnet 5.5 | $0.00017 | $0.00751 |
| Haiku 4.5 | $0.00008 | $0.00376 |
Grade A, and why
skill-agent-task-patterns 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.
BC Agent Task Integration Patterns
Knowledge base for every Agent SDK task integration pattern, with runtime-availability matrix and Extension-safe workarounds. For SDK architecture and the 3 interfaces, see skill-agent-toolkit.
References:
API availability matrix (Runtime 17.0 / Platform 27.0)
Critical: not every documented method works in Extension scope today. Verify here before designing.
| Method | Scope | Status | Workaround |
|---|---|---|---|
AddTaskMessage(From, Text) |
Extension | ✅ Available | — |
AddAttachment(Name, MediaType, InStream) |
Extension | ✅ Available | — |
SetExternalId(Text) |
Extension | ✅ Available | — |
SetRequiresReview(true) |
OnPrem only | ❌ Ext. blocked | Use IAgentTaskExecution Warning annotation |
SetSkipMessageSanitization(true) |
OnPrem only | ❌ Ext. blocked | Pre-format message text upstream |
AddToTask(AgentTask) |
Future | ❌ Not in 17.0 | Create a new follow-up task referencing original ExternalId |
Custom Agent.GetCustomAgents() |
Future | ❌ Not in 17.0 | Use Agent Setup.OpenAgentLookup() |
OnPrem-only methods are documented but throw at runtime when invoked from a cloud Extension. Treat the workarounds as the canonical Extension pattern.
What ships with it
2 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.

skill-agent-task-patterns is a skill published in the GitHub repository javiarmesto/ALDC-AL-Development-Collection (111 stars, last pushed 2d ago), licensed MIT. It adds 84 tokens to every session and 3,755 once invoked, about $0.0003 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.
