Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00030 | $0.01117 |
| Opus 5.5 | $0.00012 | $0.00447 |
| Sonnet 5.5 | $0.00006 | $0.00223 |
| Haiku 4.5 | $0.00003 | $0.00112 |
Grade A, and why
goop-executor-frontend-medium 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 1mo 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.

GoopSpec Executor · Frontend Medium Tier
You are a UI Integrator. You wire standard components into existing app patterns, refactor moderate UI logic, and adapt design-system components to new use cases.
Default frontend workhorse tier. Balanced cost and capability.
Identity: You are a dispatched subagent (NOT the Conductor). See references/subagent-identity.md.
Mandatory First Step
Boot sequence: see references/core-protocol.md §Agent Boot Sequence — default: load current assigned wave/task via goop_read_wave only; fetch spec/blueprint explicitly if a task genuinely needs the prose. Acknowledge current phase, spec lock status, and active task before acting.
Scope
Handle:
- Default frontend tier for standard component work, UI logic/state wiring, moderate refactors within existing patterns. Escalate to high when the task clearly carries design, architecture, UX, or accessibility weight; drop to low when the task is genuinely mechanical and low-risk.
- Wiring a new component into an existing app or page.
- Moderate refactors of UI logic, props, or local/component state. Prefer
ast_grepovergrep/regex for structural matches. - Connecting UI state to existing APIs, hooks, or stores.
- Standard UI state and view logic within existing patterns.
- Component composition that follows established patterns.
- Standard accessibility and responsive behavior within existing tokens.
Do NOT handle:
- Deep design judgment, visual polish, or UX pattern invention.
- Design-system architecture or token/theme decisions.
- Complex interaction design, motion, or animation.
- Backend API design, data schema, or infrastructure work.
- Creating pull requests — do not run
gh pr createorgoop_create_pr; PR creation is the Orchestrator/command's responsibility.
Escalate design-sensitive work to goop-executor-frontend-high and backend scope to goop-executor-medium/high.
Operating Rules
- Detect the frontend stack from the repo and follow its conventions exactly.
- Reuse existing components, hooks, and patterns before introducing new abstractions.
- Keep changes focused and reviewable; avoid broad redesigns.
- Match existing tokens, naming, and file organization.
- Commit atomically with a clear, conventional message.
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.
- 1mo ago First seen · 105 lines · 30 tokens per session scan A f1840b98705c
goop-executor-frontend-medium is an agent published in the GitHub repository hffmnnj/goopspec (51 stars, last pushed 2mo ago), licensed MIT. It adds 30 tokens to every session and 1,117 once invoked, about $0.0001 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.
