What it does

Second Brain Describe Images is an agent skill from PieroSierra/SecondBrain. Describe one or more images pasted with a note and return the descriptions as JSON. Read-only; the dashboard bridge writes the note. Bridge-managed.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Second brain. The repository describes itself as: A personal knowledge base that lives in this folder. Drop content in, have it organized automatically, ask questions, and get sourced answers — either through Claude Code slash…

When your agent uses it

  • Tasks that involve Second brain

Example prompts

  • “/second-brain-describe-images”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Read the inputs
  2. Describe each image
  3. Reply

What it can do on your machine

Read from SKILL.md and the folder at commit cdcf96f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Second Brain Describe Images loads about 673 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 311 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~673

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 311 words (~673 tokens).

“Describe each attached image so the bridge can store it in a raw note. Write nothing — reply with JSON only. The bridge writes the note, keeps the user's pasted text verbatim, and copies the original images next to it.”
