code-hygiene

A set of instructions for finding code left behind by separate AI coding sessions, such as unused exports, repeated logic, and types that nothing uses.

In plain words
What is it for?
Use it to review a codebase for dead exports, duplicate logic, and orphaned types.
Why use it?
It helps detect codebase drift, where changes accumulate inconsistently and leave unnecessary or duplicate code.

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 A, and why

code-hygiene 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 2d 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.

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.

code-hygiene is a skill published in the GitHub repository joryeugene/tripod (2 stars, last pushed 2d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 1,220 tokens. 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 2026-08-31.

Derive NeoHaskell concepts (Query, Command, Event, Outbound integration) through their canonical Template Haskell marker instead of hand-writing the instances the marker generates. Use whenever creating or editing a query, command, event, entity, or any concept that has a TH marker — reach for deriveQuery / command /…

Write NeoHaskell (not vanilla Haskell) code in this repo — copy-adapt discipline, the fast repair loop, and the dialect escape hatch. Use when implementing or modifying any .hs file.

neohaskell-security-design-review

Design-time security review of an approved contract-delta spec, before implementation. Runs when the spec's touches list intersects security-sensitive capabilities. Produces a LOCAL-only review record (gitignored, never pushed — a security review maps attack surface); enforced on the dev machine, not in CI.
