concise

A command that turns concise response mode on or off. In this mode, replies are kept brief.

In plain words
What is it for?
Use it to check the current setting or enable and disable brief responses through the concise command.
Why use it?
It lets you control how much detail the coding agent includes in its responses without changing the underlying work.

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.

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

concise 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 it actually says

/concise - Toggle concise mode

Toggle concise response mode on or off.

Usage

  • /concise - Show current status
  • /concise on - Enable concise mode (brief responses)
  • /concise off - Disable concise mode (normal responses)

Execution

Run the toggle command:

bash ~/.claude/hooks/concise-mode/toggle.sh $ARGUMENTS

If the toggle script doesn't exist, check ~/.claude/.concise-mode file directly:

  • File contains "off" = concise mode disabled
  • File missing or contains "on" = concise mode enabled

Report the current state to the user after toggling.

Changes

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.
