What is action-writer?

A writing assistant for action scenes such as fights, chases, sports, and other fast-moving events. It focuses on clear movement, physical space, tension, speed, and impact.

Use it to write or improve combat, chase, ranged-attack, and other action sequences. It can shape pacing, describe sensory effects, and show the consequences of hits or explosions.

Action can become confusing when readers cannot tell who moved, where they are, or what happened. This assistant helps make the sequence easier to follow and more vivid.

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	$0.00000	$0.01761
Opus 5.5	$0.00000	$0.00704
Sonnet 5.5	$0.00000	$0.00352
Haiku 4.5	$0.00000	$0.00176

Security

Grade A, and why

action-writer 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 2mo 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.
