shell-session

shell-session Tool

Stateful bash: cd, env vars, and job state persist across calls.

REQUIRED: command (one shell command, NOT a script) OPTIONAL: timeout (seconds; default 30, use 120–300 for installs/builds)

RULES:

• ONE command per turn. Read the output before proposing the next.
• State persists: set vars / cd once, reuse later.
• Never run interactive commands (vi, less, top, python bare REPL). Use non-interactive equivalents (cat, sed -i, python -c '…').
• Output ends with [exit=N cwd=… timed_out=…] — check exit=0 before claiming success.
• If timed_out=true, do NOT just retry; diagnose (longer timeout, narrower command).

EXAMPLE:

{"name": "shell-session", "input": {"command": "cd /work && ls -la"}}

EXAMPLE with timeout:

{"name": "shell-session", "input": {"command": "pip install -q requests", "timeout": 180}}

Workflow

1. One command at a time: Run a single command, read output, then proceed
2. Leverage state: Set env vars or cd once, reuse in subsequent commands
3. Check exit code: Verify exit=0 in the footer before assuming success
4. Handle timeouts: If timed_out=true, diagnose the cause rather than retrying blindly
5. Avoid interactivity: Never run editors, pagers, or REPLs; use non-interactive equivalents
