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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00639 | $0.00639 |
| Opus 5 | $0.00319 | $0.00319 |
| Sonnet 5 | $0.00128 | $0.00128 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
aifed AGENTS.md 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 5d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Common Tasks
Testing aifed in .playground/
Use .playground/ as the general scratch workspace for testing aifed during development. This includes CLI flows, edit behavior, LSP-driven operations, and other manual verification tasks.
cd .playground
../target/debug/aifed --skill
../target/debug/aifed <command>
The .playground/ directory is in .gitignore. The CLI test walkthrough provides example test cases, but .playground/ is not limited to that guide.
Dependency Management
When adding dependencies to any crate:
- Add to
[workspace.dependencies]in rootCargo.toml - Reference in crate's
Cargo.tomlwithworkspace = true
Example:
# Root Cargo.toml
[workspace.dependencies]
serde = { version = "1.0", features = ["derive"] }
# crates/my-app/Cargo.toml
[dependencies]
serde = { workspace = true }
Verification Checklist
After modifying Nix files:
nixfmt <nix file>- Format single filenixfmt $(find nix/ -name "*.nix") flake.nix- Format all Nix files at oncestatix check .- Static analysis (run from project root)
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.

aifed AGENTS.md is an instructions file published in the GitHub repository ImitationGameLabs/aifed (11 stars, last pushed 2mo ago), licensed MIT. It adds 639 tokens to every session, about $0.0032 per session on Opus 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.
