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 | $0.00058 | $0.02467 |
| Opus 5 | $0.00029 | $0.01234 |
| Sonnet 5 | $0.00012 | $0.00493 |
| Haiku 4.5 | $0.00006 | $0.00247 |
Grade A, and why
checkout-analysis 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Noibu Checkout Performance & Health Analysis
Surfaces where shoppers drop off in checkout and what to do about it, as a ranked triage board built from Noibu session, value, and error data.
How it works
Run Setup, then pick one of two behaviors from the user's prompt:
- Quick answer (one focused question) → run 1–2 queries, answer directly, offer to go deeper.
- Full analysis (broad request, bare invocation, or "yes" to the offer) → the four-step workflow below.
Full analysis flow: (1) broad overview (Q1–Q7, current + prior window) → (2) cross-reference + period-over-period → (3) pick the top 3 regressions → (4) run targeted follow-ups → render the board (one widget). Signals are flagged on change vs the prior window, not absolute level — see references/queries.md "Signal model".
Setup — before any query
Work quietly. Don't narrate plumbing — resolving the domain, loading reference files, and reading the board format all happen silently, with no "let me…" commentary. The first thing the user sees is the Step 1 overview line ("Starting with a broad look…"); after that, narrate only real analytical progress (what the data shows), never file reads or tool setup.
- Resolve the domain first; keep the company id it returns. If the user gave a domain (name or UUID), use it. If not, ask which one via
AskUserQuestionpopulated from the user's domains — don't interrogate for anything else; take the default window and proceed. If the account has exactly one domain, skip the question and use it. Domain resolution returns a company id alongside the domain UUID; some tools (priority errors, data-connection checks) need that company id too — carry both. - Load the Noibu context reference (the
querying-noibu-dataskill/reference). It maps the role-based names used here ("session query tool", "funnel depth field", etc.) to the real Noibu tools/columns and documents query constraints. If it isn't available, discover tools and field names from the live Noibu API / tool schema instead — don't stop or guess. - Confirm every field name by role before using it (from the context reference, else the live schema). Steps below name fields by role, never by hard-coded column, so when the API changes only the lookup moves.
- Default analysis window: the one in the context reference; if none, last 30 days.
- Call
list_scheduled_tasksnow — note whether any task's prompt references this domain; this sets the action-bar Schedule button label later ("Schedule insights" vs "Edit scheduled insights") without blocking rendering.
What ships with it
5 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.
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.

checkout-analysis is a skill published in the GitHub repository Noibu/ai-plugin (5 stars, last pushed 8d ago), licensed MIT. It adds 58 tokens to every session and 2,467 once invoked, about $0.0003 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.
