AIBAST Agents Library is a collection of industry-focused AI agent templates accompanied by a local server that connects agents to GitHub Copilot for language-model inference. It helps developers create and run tool-using agents and isolated project environments, with an optional cloud-backed path for persistent memory. The catalogue entries provide the repository's agents, skills, commands, hooks, and instructions.

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 | $0.02216 | $0.02216 |
| Opus 5.5 | $0.00886 | $0.00886 |
| Sonnet 5.5 | $0.00443 | $0.00443 |
| Haiku 4.5 | $0.00222 | $0.00222 |
Grade C, and why
aibast-agents-library CLAUDE.md scanned grade C with 2 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
**`main` is production.** The install one-liners (`curl ... install.sh | bash`) pull from `main`. Users get whatever is on `main`. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

What This Is
AIBAST Agents Library is the stable Microsoft downstream for the RAPP (Rapid Agent Prototype Pattern) stack. It combines the local Brainstem server, an industry agent-template catalog, the RAPP production guide, Azure deployment assets, and a Power Platform solution.
Philosophy: "engine, not experience" — this is infrastructure, not a consumer product. See CONSTITUTION.md for scope rules and governance.
Product Golden Path
The durable beta product direction is documented in
beta/GOLDEN_PATH.md:
- RAPP accelerates learning AI and teaching AI immediately after learning it.
- The resulting skill is a portable single-file agent/RAPP capability that can follow the user for life.
- Chat is the control surface.
- GitHub Copilot Brain Surgeon teaches by doing and visibly drives the beta.
- An external AI can take over the visible Brainstem or Surgeon chat to keep a user unstuck, then hand control back.
- The beta combines global and routed agents in isolated hardlinked
AGENTS_PATHworkers around an unchanged Grail kernel. - Screenshots, recordings, source Explorer, tool logs, and real
/chattests make the learning observable. - Proven RAPP/1 artifacts promote into Hippocampus and the appropriate Microsoft downstream platform without rewriting the skill or wire.
Treat this as a product-lifetime invariant. Do not replace the visible
teach-by-doing loop with hidden automation, require VS Code for the golden path,
or add beta routing fields/endpoints to brainstem.py.

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.

aibast-agents-library CLAUDE.md is an instructions file published in the GitHub repository microsoft/aibast-agents-library (8 stars, last pushed yesterday), licensed MIT. It adds 2,216 tokens to every session, about $0.0089 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
