What is extendscript-validator?

A coding assistant for Adobe ExtendScript, Adobe’s older JavaScript-based scripting system. It accounts for its ES3-era language support and Adobe application APIs.

Use it to write, review, or debug ExtendScript for InDesign, Illustrator, Photoshop, After Effects, and other Adobe Creative Cloud applications.

It helps avoid using newer JavaScript features that ExtendScript may not understand.

Origin unknown No closer match found in the catalogue.

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	$0.00398	$0.01498
Opus 5.5	$0.00159	$0.00599
Sonnet 5.5	$0.00080	$0.00300
Haiku 4.5	$0.00040	$0.00150

Measured 2mo ago against content hash 94b9e8145353, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

extendscript-validator 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.

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.
