What is verify-todo-domain?

A checker for rules covering a TODO application’s data type, create/read/update/delete actions, toggling, deletion confirmation, and matching front-end and back-end data formats. The rule labels B1–B6 come from the project.

Use it after changing TODO types, CRUD actions, toggling, deletion confirmation, or the data format shared by the front end and back end.

It helps catch mismatches between the application’s stated TODO rules and the code that implements them.

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	$0.00045	$0.01399
Opus 5	$0.00023	$0.00700
Sonnet 5	$0.00009	$0.00280
Haiku 4.5	$0.00005	$0.00140

Security

Grade A, and why

verify-todo-domain 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 10d 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.
