Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is novoads/agent-skills's own configuration. It tells Claude Code, Codex and OpenCode how to work on agent-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-skills configures →

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 C, and why

agent-skills AGENTS.md scanned grade C with 1 finding 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 19d 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

Every credit number shown to a user must come from a live `POST /v1/estimates` call made in the current session, and the user approves it before anything is generated. There are no rate tables in this repo — not in `MAST

Agent instructions

This repository is set up for AI coding agents (Cursor, Claude Code, Copilot-style tools, etc.) to generate AI video and image assets via the API documented in this repo.

First-time setup

If .env or MASTER_CONTEXT.md do not exist, tell the user to run ./scripts/setup.sh.

When the session IS the setup ("help me set this up"), setup is the whole job and the final report is SHORT — the few sentences a non-developer wants, not an engineering log. ./scripts/setup.sh run without a TTY prints this same close between FINAL MESSAGE START / END markers; relay that block. The script and the template below are mirrors — change them together. One or two status lines, then:

Setup's done — your key works. (or, when the key is missing:) One step left, the only one I can't do: create an API key at https://novoads.ai/dashboard/settings?tab=api, paste it into .env, and tell me — I'll verify it. (No account yet? Plans start at $15/month (Starter, 200 credits). Current prices: novoads.ai/en/pricing (as of 2026-10-08).) (On macOS and on Linux with a desktop session, setup opens .env itself and the line becomes "I've opened .env for you — paste the key on the NOVOADS_API_KEY line, save, and tell me." It is skipped over SSH, in CI, and under NOVOADS_SETUP_NO_OPEN=1.)

What you can ask for now:

  • "Make a UGC video ad for my product" — a presenter speaks your script
  • "Make static image ads from this photo" — the 40-template library, run in batches
  • "Clone my competitors' ads" — finds their live ads, ranks them, and clones the best one for your product. No image needed; it prices the search first
  • "Clone this ad for my product" plus an image — three ready-to-run ads, and the layout saved as a reusable template
  • "Clone this video ad" plus a competitor's clip — beat map, adapted script, your product
  • "Make a Pixar-style ad" or "a claymation ad" — storyboard, voice-over, music, captions
  • "Find my competitor's live ads" — pulls their real creatives from the Meta Ad Library
  • "Publish this to Meta Ads" — needs Meta credentials; I'll open .env and walk you through
  • Also: YouTube thumbnails, burned-in captions, b-roll cutaways, a music bed

Drop product photos into references/products/ and describe the ad you want. Every generation is priced by a live estimate and shown to you before anything is spent.

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.
