What is conjure AGENTS.md?

Repository-specific instructions for Conjure, an Elixir library for working with Anthropic Agent Skills. They describe the project, its build commands, tests, supported execution backends, and file storage options.

Use them when installing dependencies, changing Conjure, running its tests, formatting code, checking types, linting, or compiling it.

They give a coding agent the project context and the checks expected before changes are considered ready. Elixir is a programming language, and Mix is its build and test tool.

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.

Model	Per session	Once invoked
Fable 5.1	$0.02530	$0.02530
Opus 5.5	$0.01012	$0.01012
Sonnet 5.5	$0.00506	$0.00506
Haiku 4.5	$0.00253	$0.00253

Security

Grade B, and why

conjure AGENTS.md scanned grade B with 1 finding 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- Skills can execute arbitrary code - audit before loading

Project Overview

Conjure is an Elixir library for Anthropic Agent Skills with Claude models. It provides:

Unified Session API - Conjure.Session.chat/3 works across all backends
4 Execution Backends - Local, Docker, Anthropic (hosted), Native (BEAM)
Skill Loading - Parse SKILL.md files with YAML frontmatter, load .skill ZIP packages
Pluggable Storage - Local, S3, Tigris backends for session file management
API-Agnostic - No HTTP client bundled; consumers provide API callbacks

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.

conjure AGENTS.md is an instructions file published in the GitHub repository holsee/conjure (10 stars, last pushed 10mo ago), licensed Apache-2.0. It adds 2,530 tokens to every session, about $0.0101 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
