What is target-brief-studio?

An end-to-end workflow for investigating an unfamiliar target and turning the findings into a brief with images and a draft summary video.

Use it to collect target context, explore an unfamiliar subject, synthesize findings, render brief images, create a summary video, and prepare a review preview.

It coordinates several analysis and content-making stages in one repeatable process. This helps turn raw investigation into a preview-ready delivery package.

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	$0.00020	$0.00600
Opus 5	$0.00010	$0.00300
Sonnet 5	$0.00004	$0.00120
Haiku 4.5	$0.00002	$0.00060

Measured 4d ago against content hash f22b2493f0d8, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

target-brief-studio 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 4d 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.
