open

A command that opens a selected workspace in VS Code and shows its notes sidebar. A workspace is a project folder with its related editor settings and notes.

In plain words
What is it for?
Use it to open a workspace by repository and name, by name across repositories, or from the current folder.
Why use it?
It removes the need to find the project folder and open the right editor setup manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

open 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 yesterday.

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.

What it actually says

Open a workspace in VS Code with notes sidebar.

Resolve the metarepo path by reading ~/.claude/workspace-config.json and expanding ~ to $HOME.

The user's request: $ARGUMENTS

Steps

  1. Read ~/.claude/workspace-config.json to get the metarepo path. Expand ~ to $HOME.
  2. Determine which workspace to open:
    • If <repo>/<workspace> specified, use it
    • If just <workspace>, search across repos
    • If no argument, infer from cwd
    • If unable to determine, list workspaces and ask
  3. Verify workspace exists at <metarepo>/repos/<repo>/<workspace>/.
  4. Run the open script:
    bash ${CLAUDE_PLUGIN_ROOT}/scripts/workspaces/open-workspace.sh <repo> <workspace>
    
  5. Report what was opened.

Important

  • Always resolve metarepo from ~/.claude/workspace-config.json, never hardcode paths.
  • Workspaces live at <metarepo>/repos/<repo>/<workspace>/.
  • Notes live at <metarepo>/notes/<repo>/<workspace>/.
  • Requires VS Code CLI (code) in PATH.
  • If code is not available: VS Code > Cmd+Shift+P > "Shell Command: Install code command in PATH".

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.
