A three-stage workflow for turning an idea into tested code: explore the requirements, write an implementation plan, then repeatedly build, test, and commit the changes.

Use it to clarify a feature, create specifications, produce an IMPLEMENTATIONPLAN, or run an unattended build-and-test loop.

It helps keep brainstorming, planning, and implementation in the right order. It can choose the next stage from trigger words and the project's current state, asking you when instructions conflict.

Origin unknown No closer match found in the catalogue.

Token cost

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	$0.00110	$0.02550
Opus 5	$0.00055	$0.01275
Sonnet 5	$0.00022	$0.00510
Haiku 4.5	$0.00011	$0.00255

Security

Grade A, and why

goal-loop 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 8d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/clean-state.sh, scripts/loop.sh, tests/test-loop-args.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

goal-loop is a skill published in the GitHub repository AragornZJF/goal-loop (10 stars, last pushed 2mo ago), with no licence file. It adds 110 tokens to every session and 2,550 once invoked, about $0.0006 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 2026-08-31.
