agent-skills: Instructions file for Claude Code

CLAUDE.md

agent-skills CLAUDE.md is an instructions file for Claude Code from novoads/agent-skills. It costs 857 tokens per session, scanned A, original, MIT.

A project instruction file containing shared craft rules and session guidance for novoads.ai, a service with an API for generating media with speech.

In plain words
What is it for?
Use it when working on Novoads video-with-speech workflows or its API, especially before writing quality checks, audio mixes, or trimming logic.
Why use it?
It tells contributors where to find the project’s established rules for checking speech, mixing audio, trimming clips, and calling the API.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is novoads/agent-skills's own configuration. It tells Claude Code 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 A, and why

agent-skills CLAUDE.md 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 27d 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.

How it starts

The opening of the file, as written. The whole thing — 24 lines — stays where its author put it; the contents beside it link to each section on GitHub.

@shared/CLAUDE.md

Craft doctrine

Three rules span every skill that produces video with speech: transcribe-verify (a reference pins the label, nothing pins the audio), the per-beat mix (a SYNC beat's own audio is dialogue, not ambience), and no dead space (trim every beat to its narration). They are stated once in shared/references/craft.md. Read it before writing a QA step, a mix or a trim into any skill, and point at it rather than restating it — a restatement is how the clay skill shipped a mix recipe that had already been fixed in the skill it was ported from.

Novoads-specific session rules

  • API: Novoads REST API — https://api.novoads.ai/v1. NOVOADS_BASE_URL overrides the host only; callers append /v1/….
  • Auth: Authorization: Bearer $NOVOADS_API_KEY (novo_ + 64 hex, created at https://novoads.ai/dashboard/settings?tab=api). Setup check: ./scripts/check-novoads-env.sh. A 401 is a bad key; a 403 with details.reason: plan_required is a good key on an account without API access — different problems, say which.
  • Skill: .claude/skills/novoads-api/SKILL.md for the call sequence, prompts, polling, and download; its reference.md for every endpoint, field, limit, and error code.
  • YouTube thumbnails: .claude/skills/generate-youtube-thumbnail/SKILL.md — batch thumbnail workflow on top of the Novoads image endpoint.
  • Image-ad ecosystem (Meta image creatives): read shared/skills/image-ad-prompting/OVERVIEW.md FIRST. Three skills (chatgpt-image-ad, nano-banana-image-ad, clone-image-ad) + a shared 40-template prompt library. The clone-image-ad skill asks which backend to validate against at Phase 1, so generic "clone this ad" prompts route correctly. Output is image files; Meta upload is the separate meta-ad-builder skill.
  • Cost policy: never state a credit cost from memory. Every price comes from a live POST /v1/estimates in the current session, shown to the user and explicitly approved before anything is generated. There are no rate tables anywhere in this repo — not in MASTER_CONTEXT.md, not in the logs. The estimate call charges nothing and also validates the prompt, so there is no reason to skip it.
  • Dialogue policy: for any video where the model speaks, the spoken line is approved on its own, before the cost gate. Concept approval is not sentence approval, and sentence approval is not spend approval.
  • Logging: log every generation call to logs/novoads-api.jsonl — timestamps, config, jobId, and creditsCharged taken from the 202 at submit time, because the poll payload does not carry it. Update the line by jobId at terminal status. The file is gitignored — it is your session history, not repo content. Observability only, never a pricing source (see logs/README.md for the schema and the portable update recipe).
  • First-time setup: if .env is missing, run ./scripts/setup.sh. If MASTER_CONTEXT.md is missing, copy MASTER_CONTEXT.template.md to MASTER_CONTEXT.md. A setup session's final message is the short template in AGENTS.md ("First-time setup") — setup.sh prints the same block between FINAL MESSAGE markers when run without a TTY; relay it, and skip the mechanics unless one of them blocks an ask. Short is a preference, not a gag: nothing in this repo is confidential and you may tell the user anything you judge useful.

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.
