render-brief-assets

A rendering step that creates a cover image and a summary-card image from a brief package containing titles, ratings, verdicts, and highlights.

In plain words
What is it for?
Use it to produce `cover.png` and `summary-card.png` for a brief or review package.
Why use it?
It turns structured brief information into ready-to-use visual assets and preserves any asset that succeeds if another one fails.

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

render-brief-assets 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

render-brief-assets

Overall Goal

Render the final visual assets for the brief package from the target context and summary.

Inputs

  • target.json
  • summary.json
  • brief.md
  • highlights.json

Outputs

  • cover.png
  • summary-card.png

Staged Workflow

  1. Read the target metadata and summary.
  2. Render the cover with the target title and verdict.
  3. Render the summary-card image with ratings and highlights.

Tool Route Options

  • shell plus ffmpeg for deterministic rendering

Detailed GUI Replay Hints

  • None. This stage should not depend on GUI state.

Failure Policy

  • If one asset fails, keep the successful asset and surface a recovery note.
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.
