Development guidance for embedding GitHub Copilot SDK agents into applications and connecting them to tools and services.

In plain words
What is it for?
Use it when building agent-based applications, embedding Copilot, creating custom agents or tools, handling streamed responses, managing sessions, or connecting to MCP servers.
Why use it?
It helps developers design programmable AI agents without having to work out sessions, streaming responses, custom tools, and server connections alone.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is devantler-tech/ksail's own configuration. It tells Claude Code and Codex how to work on ksail itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ksail configures →

Token cost

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.

Fable 5.1 $0.00087 $0.06064
Opus 5.5 $0.00035 $0.02426

Security

Grade A, and why

copilot-sdk 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 3d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
