Gemini delegate

Skill davdittrich/gemini-delegate

A Claude Code skill that delegates coding tasks to Google's Gemini CLI via the Agent Client Protocol (ACP) -- structured JSON-RPC communication instead of shell subprocess piping.

Gemini Delegate (ACP)

Delegate tasks to Gemini via ACP bridge. Verification MANDATORY.

Bridge Mandates

MANDATORY: scripts/gemini_bridge.py only. NEVER call gemini directly.
Safe I/O: Use --prompt-stdin to prevent deadlocks.
Persistence: Use --output-file AUTO for unique result files.
Sessions: Capture/reuse SESSION_ID from JSON for follow-ups.
Timeout: Total 600s (10m). First chunk 300s.

Grounding & Web Search

Prefix: Queries MUST start with WebSearch: (e.g., WebSearch: API news 2026).
Grounding: Prefix forces web grounding. No prefix = fabrication risk.
Fallback: If bridge fails (timeout/crash), use built-in WebSearch. Report in one line.

Routing & Tasking

Task	Model	Template
Review (<200 lines)	`gemini-3-flash-preview`	Focused review
Bug/Arch (>3 files)	`gemini-3.1-pro-preview`	Tool-assisted
Search/Info	`gemini-3-flash-preview`	Web search
Adversarial/Plan	`gemini-3.1-pro-preview`	Critique

CLI Flags

Flag	Description	Default
`--prompt`	Prompt text
`--prompt-file`	Read prompt from file
`--prompt-stdin`	Read from stdin (MANDATORY for automation)
`--session-id`	Resume specific session
`--new-session`	Force fresh session
`--sessions-dir`	Override session storage dir
`--cd`	Workspace root directory	`.`
`--timeout`	Total max wall-clock seconds	600
`--idle-timeout`	Max seconds between chunks	120
`--first-chunk-timeout`	Max seconds for first chunk	300
`--verbose`	Print heartbeat markers to stderr
`--output-file`	Write JSON to file (`AUTO` for unique temp)
`--approve-edits`	Allow file writes within `--cd` scope
`--cache`	Content-addressed git-based caching	off
`--cache-ttl`	Cache TTL in seconds (1-2592000)	86400
`--clear-cache`	Clear result cache and exit
`--parallel-models`	Comma-separated models for parallel runs
`--log-feedback`	Append feedback entry `VERDICT	TASK
`--model`	Gemini model to use

Output Schema

{
  "success": true,
  "SESSION_ID": "...",
  "agent_messages": "...",
  "read_file_count": N,
  "fallback_occurred": boolean,
  "requested_model": "...",
  "actual_model_selection": "specified"|"automatic",
  "tool_calls": [...],
  "token_estimate": { "estimated_cost_usd": 0.00 }
}

STOP & VERIFY (Red Flags)

Violating the letter of these rules violates the spirit. STOP if:

read_file_count is 0 for code analysis (Gemini is guessing).
Response contains functions not present in source files.
Web search response lacks specific source URLs.
Requested Pro failed (fallback_occurred: true). Alert user immediately.
Calling gemini directly. Revert and use bridge.
Omitted WebSearch: prefix. Re-run with prefix.

Rationalization Table

Excuse	Reality
"I know this code already."	Code changes. RE-VERIFY key logic via `read_file`.
"File names explain it."	Guessing = fabrication. READ content.
"I'll skip WebSearch: prefix."	Internal 2026 knowledge is fabrication. GROUND every claim.
"Pro failed, Flash is fine."	pro-preview is the tier for logic. Fallback must be reported.

Permissions & Logs

Write: --approve-edits required for file writes.
Feedback: Log outcome via --log-feedback after every task.
Escalation: Rejection rate >50% -> escalate model tier.
