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.

Security

Grade D, and why

agents_environment_setup AGENTS.md scanned grade D 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 7d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

AGENTS.md — working in agents_environment_setup

AES is an Agent Developer Environment Manager. One command, aes setup, takes a machine from nothing to a complete, verified AI coding environment, and exits 0 only when it is done.

This file is the working guide: where things are, how to run them, how the swarm coordinates, and which traps cost someone an hour. The design contract — architecture, invariants, the Go type shapes, exit codes — lives in docs/COMPREHENSIVE_FOR_AES.md. Read that first. This file assumes you have.


Orientation

The repo is at the plan-locked, code-in-progress stage. docs/COMPREHENSIVE_FOR_AES.md is the authoritative spec and is treated as a contract, not a suggestion. When code and spec disagree, the spec wins and the code is wrong.

cmd/aes/            main entrypoint (thin; all logic lives in internal/cli)
internal/
  manifest/         Tool/Target/Verify types + validation. Pure: stdlib + yaml.v3.
  catalog/          loads tools/**/tool.yaml, indexes by name/category/tag
  platform/         Host{OS,Arch,Manager,Prefix}, Supports/Target/Has
  resolver/         Resolve(c, req, h) -> []Action. deps DAG + cycle detection
  selection/        Selection -> []Action, the ONE path both frontends call (I13)
  verifier/         the ground truth. presence + version. never reads state
  state/            ~/.aes/state.json, atomic. a CACHE, not truth

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.
