Agy Delegate (Cursor → agy CLI)

Spawn and steer agy turns from Cursor via the local CLI. agy must be installed and on PATH (typically ~/.local/bin/agy).

vs libr-delegate

Caller need	Skill
Cursor → agy (Gemini/Claude/etc. CLI)	This skill
Cursor → LibrAgent HTTP /api/sessions	libr-delegate

Preconditions

# Bash (Linux / macOS)
command -v agy >/dev/null || { echo "agy not on PATH"; exit 1; }

# PowerShell (Windows)
if (-not (Get-Command agy -ErrorAction SilentlyContinue)) { Write-Error "agy not on PATH"; exit 1 }

Only run agy models when the user asked for a non-default model, or the default id failed as unknown/stale.

Workflow

1. Write a self-contained handoff (agy does not see this Cursor chat)
2. Use this skill’s default --model (below). Do not pick a different model for “harder” work, cost, or preference
3. Run print mode (-p / --print) from the relevant cwd or pass --add-dir
4. Read stdout as the result; on failure check exit code and stderr
5. Follow-ups: new -p with fuller context, or --conversation <id> / --continue when resuming the same thread — same model as the first turn
6. Optional: --output-format json when you need status / response fields

Recipes: references/cli.md. Handoff / isolation: references/handoff.md. Optional wrappers: scripts/run.sh (Bash) or scripts/run.ps1 (PowerShell).

Default invoke (unattended)

Default model (do not change): gemini-3.8-flash-high

Linux / macOS (Bash)

agy -p "$TASK" \
  --model gemini-3.8-flash-high \
  --dangerously-skip-permissions \
  --print-timeout 300s \
  --add-dir "$WORKSPACE_ABS"

# Using bundled bash wrapper
./scripts/run.sh --dir "$WORKSPACE_ABS" -- "$TASK"
./scripts/run.sh --json --dir "$WORKSPACE_ABS" -- "$TASK"

Windows (PowerShell)

[!IMPORTANT] In PowerShell, unquoted multiline variables split across spaces. Always quote "$TASK" or pass via Here-String (@' ... '@).

$TASK = @'
Goal: ...
Scope: ...
'@

& agy -p "$TASK" `
  --model gemini-3.8-flash-high `
  --dangerously-skip-permissions `
  --print-timeout 300s `
  --add-dir "$WORKSPACE_ABS"

# Using bundled PowerShell wrapper (recommended on Windows)
& .agents/skills/agy-delegate/scripts/run.ps1 -Dir "$WORKSPACE_ABS" -Task "$TASK"
& .agents/skills/agy-delegate/scripts/run.ps1 -Dir "$WORKSPACE_ABS" -Json -Task "$TASK"

• Omit --dangerously-skip-permissions / -NoSkipPerms when the user must approve tool use
• Raise timeout for long coding/research turns; 0 waits until completion
• Repeat --add-dir / -Dir for extra roots
• Use --output-format json / -Json to parse status (SUCCESS / …) and response

Model selection (strict)

Rule	Action
Normal delegate	Always --model gemini-3.8-flash-high (or omit --model when using scripts/run.sh / AGY_MODEL default)
User names a model	Use exactly that id (verify with agy models if it fails)
Agent judgment (“this needs Pro/Claude”)	Forbidden — keep the default

Do not hardcode alternate model names into invocations. Do not “upgrade” to Pro/Opus/Claude unless the user asked. If agy rejects the default id as stale, list agy models and pick the closest flash-high equivalent — still do not silently jump to Pro.

Isolation (critical)

The agy session is not a clone of this Cursor chat:

• Default cwd is whatever shell cwd you launch with — set it, or pass absolute --add-dir
• Put objective, scope, paths, and output format in the -p prompt
• Require deliverables in stdout (final assistant text / JSON response)
• Do not assume Cursor files, notes, or skills are visible inside agy

Anti-patterns

• Calling nonexistent MCP tools (agy__*, spawnAgy, …)
• Vague prompts that rely on Cursor thread context
• Treating non-zero exit or JSON status ≠ SUCCESS as success
• Using this skill for LibrAgent Session API (use libr-delegate)
• Interactive-only flags (-i) for automation — prefer -p
• Changing --model without an explicit user request (including Pro/Claude “for quality”)
• Unquoted variables in PowerShell (agy -p $TASK splits words into CLI flags; always quote or use Here-Strings)
• Bash syntax in PowerShell (&&, \, ./scripts/run.sh — use ;, `, or run.ps1)
• Script sprawl: fabricating ad-hoc .bat/.py/.js wrappers instead of using direct invocations or the provided run.sh/run.ps1
