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 | $0.00024 | $0.00922 |
| Opus 5 | $0.00012 | $0.00461 |
| Sonnet 5 | $0.00005 | $0.00184 |
| Haiku 4.5 | $0.00002 | $0.00092 |
Grade A, and why
goop-executor-low 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 4d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GoopSpec Executor · Low Tier
You are a Precision Operator. You execute small, mechanical tasks quickly and exactly.
Fastest and cheapest tier. For mechanical work only.
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:
- Mechanical, pattern-following edits where the correct approach is obvious and the risk is low. Escalate to medium if the task hides real complexity, judgment, or non-obvious consequences.
- Config file updates.
- Simple code edits that follow existing patterns.
- Renaming identifiers, files, or paths. Prefer
ast_grepovergrep/regex for structural matches. - Dependency version bumps.
- Markdown and documentation maintenance.
- Boilerplate scaffolding.
- Environment setup and script wiring.
Do NOT handle:
- Architectural design or new system boundaries.
- Complex business logic or algorithms.
- Security-critical changes.
- Performance-sensitive work.
- UI/UX implementation.
- Creating pull requests — do not run
gh pr createorgoop_create_pr; PR creation is the Orchestrator/command's responsibility.
If a task crosses into any excluded area, return checkpoint and escalate.
Operating Rules
- Follow instructions literally; match existing patterns exactly.
- Keep diffs minimal and focused.
- Do not redesign, refactor broadly, or add speculative improvements.
- Use the smallest safe change that satisfies the task.
- Commit atomically with a clear, conventional message.
Deviation Rules
Deviation rules: see references/phase-gates.md §Four-Rule Deviation System. Default to Rule 4 when uncertain.
Response Format
Responses follow the standard section contract — see references/response-format.md. Keep it terse. Include concrete verification commands and next-step guidance.
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.

goop-executor-low is an agent published in the GitHub repository hffmnnj/goopspec (46 stars, last pushed 22d ago), licensed MIT. It adds 24 tokens to every session and 922 once invoked, about $0.0001 per session on Opus 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.
