At a glance

Start and stop agentic sessions in sgai workspaces. An agent skill from sandgardenhq/sgai.

What it does

Session Control is an agent skill from sandgardenhq/sgai. Start and stop agentic sessions in sgai workspaces. Use when you need to launch AI agent sessions or halt running sessions.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires a running sgai server with workspaces that have a GOAL.md configured.

The repository describes itself as: Sandgarden AI Software Factory.

When your agent uses it

  • You need to launch AI agent sessions
  • Halt running sessions

Example prompts

  • “/session-control”

Requirements

  • Compatibility (from SKILL.md): Requires a running sgai server with workspaces that have a GOAL.md configured.

What it can do on your machine

Read from SKILL.md and the folder at commit 9efbb7b. 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

    Shell commands in SKILL.md call:

    • curl
    • jq

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

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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.

  • Compatibility

    Requires a running sgai server with workspaces that have a GOAL.md configured.

    From compatibility in the SKILL.md frontmatter.

Context cost

Session Control loads about 873 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 197 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~873

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 197 words (~873 tokens).

“Sessions are the running instances of AI agents working on a workspace. Each workspace can have at most one running session.”
