What is edge-case-reviewer?

A code review focused on unusual inputs, failure handling, cleanup, and server-side checks.

Use it to review backend code for boundary cases, error propagation, resource cleanup, and input validation.

It helps find bugs that appear with missing, empty, extreme, or invalid data and makes failures less likely to leave resources open.

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	$0.00093	$0.03344
Opus 5.5	$0.00037	$0.01338
Sonnet 5.5	$0.00019	$0.00669
Haiku 4.5	$0.00009	$0.00334

Measured 16d ago against content hash 160f6a8cce82, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade C, and why

edge-case-reviewer scanned grade C 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 16d 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.

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.
