video-analysis

video-analysis is a skill for Claude Code from sonilo-ai/skills. It costs 109 tokens per session (2,794 once invoked), scanned A, original, MIT.

A video-review tool that returns a written plan for adding sound to footage. The plan divides the video by time and includes ready-to-use prompts for generating music or other audio; it does not create files itself.

In plain words
What is it for?
Use it when deciding how a video should sound or when an earlier generated result missed the intended mood, timing, or events.
Why use it?
It turns unclear requests such as “make this sound good” into specific options based on what happens in the footage. The analysis is a paid Sonilo call.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is **Setup:** See the [setup-api-key](../setup-api-key) skill to connect the Sonilo MCP server and authenticate — `sonilo login` (no key) or `SONILO_API_KEY`..

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

video-analysis scanned grade A 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sonilo Video Analysis

Hand Sonilo a video and it returns a creative brief for scoring it: a time-aligned segments plan (what each stretch of footage wants) plus one or more variations, each a single ready-to-use generation prompt.

This skill generates nothing. No audio, no video, no file. Its whole output is text, and the text is the input to the next call.

Setup: See the setup-api-key skill to connect the Sonilo MCP server and authenticate — sonilo login (no key) or SONILO_API_KEY.

⚠️ Cost: this is a paid call, even though nothing is generated. Billing has a 10-second floor and variants_num is billed per brief, so 3 variations cost 3×. Only call it when the user has actually asked. Check get_account_services (see the account skill) if you're unsure whether free-trial runs remain.

When to reach for this

Use it when:

  • The user doesn't know what the video should sound like. "Make this sound good" is not a prompt. Analyze first, show them the variations, let them pick.
  • A first generation missed. A bad result usually means a bad brief, not a bad model. Analyzing beats rerolling: a reroll is a fresh charge on the same weak prompt.
  • The video has distinct sections and you want them scored deliberately rather than as one continuous bed. segments gives you the section boundaries the footage actually has.

Do not use it when the user already told you what they want. If they said "tense synths, drop at the 20-second mark", go straight to video-to-music — analysis would just be an extra charge between them and their track.

Transport: MCP or CLI

Pick one at the start of the session and stay on it. Do not mix the two inside a single job, and do not announce the choice.

  1. Sonilo MCP tools visible in this session (analyze_video and friends) — use them. This is the preferred path: it needs no shell, and it is the only one that survives a very long generation. If a call fails to authenticate — rather than failing on its inputs — this transport is not usable in this session: go to 2 instead of retrying it.
  2. No usable Sonilo MCP tools, but sonilo account exits 0 — use the CLI commands below. Same API, same account, same credential file. Probe with sonilo account, not sonilo whoami: whoami exits 0 even when signed out, so it cannot tell the two states apart.
  3. Neither — stop and run the setup-api-key skill. Do not call api.sonilo.com with curl to work around it; both transports handle uploads, polling and retries that a bare request does not.

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.

video-analysis is a skill published in the GitHub repository sonilo-ai/skills (114 stars, last pushed 3d ago), licensed MIT. It adds 109 tokens to every session and 2,794 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
