What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.01581 |
| Opus 5.5 | $0.00017 | $0.00632 |
| Sonnet 5.5 | $0.00008 | $0.00316 |
| Haiku 4.5 | $0.00004 | $0.00158 |
Grade A, and why
subagent-delegation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Subagent Delegation Protocol
Delegation is not an optimization in GSD — it is the mechanism that makes the quality thresholds in PROJECT_RULES.md achievable. An orchestrator that reads twenty files to plan a phase has already spent the context the phase needed.
Requirements
Native subagents require Antigravity 2.0 or later (invoke_subagent).
Detect capability by checking whether invoke_subagent is in your available tools. Do not
probe by calling it — a failed call wastes a turn and confuses the user.
| Capability | Behavior |
|---|---|
invoke_subagent available |
Delegate per this protocol |
| Not available | Inline fallback (see below) |
Plan requirements: none beyond 2.0. Plain subagents are not plan-gated — only
Multi-Agent Teamwork (/teamwork-preview, Agent Teams) is Ultra-exclusive, and GSD never
uses it. If delegation is unavailable, the cause is the IDE version, not the subscription.
What to Delegate
| Work | Subagent | Why |
|---|---|---|
| Executing a PLAN.md | gsd-executor |
One clean context per plan is the core GSD promise |
| Authoring plans for a phase | gsd-planner |
Plan authoring reads spec + roadmap + research |
| Verifying a phase | gsd-verifier |
Independence requires a context that never saw the work |
| Codebase mapping / research | gsd-researcher |
Exploration is the largest single context cost |
| Diagnosing a bug | gsd-debugger |
A polluted context repeats its own failed hypotheses |
Keep in the orchestrator: argument parsing, file existence checks, wave grouping, reading compact subagent results, updating STATE.md and ROADMAP.md, and talking to the user.
Everything else is delegable. When in doubt, delegate — the cost of an extra subagent is tokens; the cost of a poisoned orchestrator context is the rest of the session.
Invocation
Call invoke_subagent, targeting the subagent by the name in its .agents/agents/*.md
definition. The tool's exact parameter schema is supplied by the IDE — follow it. This
protocol governs what you put in the prompt, not the wire format.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

subagent-delegation is a skill published in the GitHub repository toonight/get-shit-done-for-antigravity (975 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 1,581 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
