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 | $0.00048 | $0.01740 |
| Opus 5 | $0.00024 | $0.00870 |
| Sonnet 5 | $0.00010 | $0.00348 |
| Haiku 4.5 | $0.00005 | $0.00174 |
Grade A, and why
loop-workflow-planner 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 2d 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.

Loop Workflow Planner
Purpose
Create a platform-neutral Loop Workflow Contract for standard or deep work that must iterate until measurable acceptance criteria pass.
This skill does not implement code. It defines objective, scope, verification, retry limits, stop conditions, independent review, and memory update rules so Codex, GPT-based agents, Claude, and generic coding agents can execute the same workflow without depending on Claude-only commands.
When To Use
Use this skill when the task is Standard Workflow or Deep Workflow and one or more are true:
- the user asks to continue until lint, typecheck, build, visual QA, CI, or another measurable check passes;
- verification may fail and repair is in scope;
- a repeated failure already happened;
- a bugfix, CI repair, refactor, or UI implementation needs bounded retry;
- independent review should judge completion;
- the work may need resumable memory;
- multiple agents or worktrees are being considered.
When Not To Use
Do not use for:
- Fast Lookup;
- one obvious typo or type error;
- tiny direct edits;
- pure explanation;
- design-only direction with no iterative verification;
- platform-specific
/goal,/loop, or/schedulecommands without a platform-neutral contract; - unbounded autonomous work.

What ships with it
1 file 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.
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.

loop-workflow-planner is a skill published in the GitHub repository ytvee-dev/webdev-agent-kit (5 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 48 tokens to every session and 1,740 once invoked, about $0.0002 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.
