What is wreckit AGENTS.md?

Guidelines for working on Wreckit, a command-line tool whose workflow can take work from research and planning through implementation and a pull request. They require checking the project's specifications and actual code before deciding what exists.

Use them to implement Wreckit features from specifications, run its checks, and execute all or selected incomplete work items through the command line.

They reduce the risk of implementing a feature that already exists or contradicts the project's planned design. They also document the commands for building, testing, checking types, linting, and running work items.

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	$0.02778	$0.02778
Opus 5.5	$0.01111	$0.01111
Sonnet 5.5	$0.00556	$0.00556

Security

Grade B, and why

wreckit 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 2mo 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.

Wreckit Agent Guidelines

Specifications

IMPORTANT: Before implementing any feature, consult the specifications in specs/README.md.

Assume NOT implemented. Many specs describe planned features that may not yet exist in the codebase.
Check the codebase first. Before concluding something is or isn't implemented, search the actual code. Specs describe intent; code describes reality.
Use specs as guidance. When implementing a feature, follow the design patterns, types, and architecture defined in the relevant spec.
Spec index: specs/README.md lists all specifications organized by phase.

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.
