What it does

Treehouse is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Safely acquire, inspect, and return leased Treehouse workspaces.

Its SKILL.md is about 1.5k 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: IntelliJ IDEA & IntelliJ Platform.

Example prompts

  • “/treehouse”

Requirements

  • Pre-approved tools (allowed-tools): Bash(../../../community/tools/treehouse.cmd read:*), Bash(../../../community/tools/treehouse.cmd write:*), Bash(../../../tools/treehouse.cmd read:*), Bash(../../../tools/treehouse.cmd write:*), Bash(./community/tools/treehouse.cmd read:*), Bash(./community/tools/treehouse.cmd write:*), Bash(./tools/treehouse.cmd read:*), Bash(./tools/treehouse.cmd write:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Before an acquire, check that the built-in request_permissions tool is available. If it is
  2. Run from this skill directory, and request two approval prefixes. They are
  3. A change of the working directory of a tool does not add the leased workspace to the writable
  4. If the grant is denied, do not enter, edit, or run a command in the leased workspace. Return

What it can do on your machine

Read from SKILL.md and the folder at commit 562e3a2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(../../../community/tools/treehouse.cmd read:*)
    • Bash(../../../community/tools/treehouse.cmd write:*)
    • Bash(../../../tools/treehouse.cmd read:*)
    • Bash(../../../tools/treehouse.cmd write:*)
    • Bash(./community/tools/treehouse.cmd read:*)
    • Bash(./community/tools/treehouse.cmd write:*)
    • Bash(./tools/treehouse.cmd read:*)
    • Bash(./tools/treehouse.cmd write:*)

    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 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

Treehouse loads about 1.5k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 827 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 827 words (~1,507 tokens).

“Use this skill when a task needs an isolated workspace. Read Workspace Isolation for the policy around it. The CLI wraps only the leased lifecycle of Treehouse: read status, write acquire, and write return. It never installs Treehouse, and it…”
