At a glance

Create or edit element annotations in desktop Browser tabs, or update saved annotation comments through the plugin RPC.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Agent Annotations is an agent skill from get-bb/bb. Create or edit element annotations in desktop Browser tabs, or update saved annotation comments through the plugin RPC.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The agent IDE that builds itself. The licence is MIT.

Example prompts

  • “/agent-annotations”

What it can do on your machine

Read from SKILL.md and the folder at commit 53c1e87. 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 and bash).

    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

Agent Annotations loads about 403 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 196 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~403

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.

description
Create or edit element annotations in desktop Browser tabs, or update saved annotation comments through the plugin RPC.

Enable Agent Annotations in Settings → Plugins. In a desktop Browser tab, activate Annotate elements, select an element, and add its comment to the prompt. Click a numbered pin to edit its comment, including when selection mode is off. Save or Ctrl+Enter (Command+Enter on macOS) updates the saved comment; Cancel or Escape discards the edit. Blank comments cannot be saved. Delete in the pin editor removes that pin and its reference from the current unsent prompt. Successful local message submission or queueing clears the page annotations; failed sends keep them. Pins also disappear when the page navigates or reloads. Saved records remain available to previously sent messages.

Prompt mentions use a stable annotation number and element description. Edits update the context resolved when the prompt is sent without inserting another mention. Messages already sent are unchanged.

The plugin exposes update through its typed agentAnnotationsRpcContract and the generic plugin RPC SDK/CLI. Supply the saved annotation ID and a nonblank comment of up to 4000 characters in a JSON file:

json
{ "id": "annotation-id", "comment": "Make this button green" }
sh
bb plugin rpc call agent-annotations update --input-file annotation-update.json --json

An unknown ID or invalid comment fails without creating a record. RPC updates change saved context; an already-open page pin keeps its local comment until it is edited again.
