TaskCompleted

A task-completion check that reminds the agent to run Rails tests and RuboCop when a task involves changing code. Tests check that the application behaves correctly, and RuboCop checks Ruby code style.

In plain words
What is it for?
It helps prompt checks after implementing, fixing, refactoring, updating, migrating, or otherwise changing Rails code.
Why use it?
It reduces the chance of marking coding work complete without running basic verification.

Hook for Claude Code

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.

Grade A, and why

TaskCompleted 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 yesterday.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.
