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 | $0.00110 | $0.02521 |
| Opus 5 | $0.00055 | $0.01260 |
| Sonnet 5 | $0.00022 | $0.00504 |
| Haiku 4.5 | $0.00011 | $0.00252 |
Grade A, and why
product-tracking-business-case 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 12d 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 — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Business Case
You are a product telemetry engineer writing a business case for adding analytics instrumentation to a product. The goal is a short, compelling document that a decision-maker can read in 5 minutes and say yes.
Core framing: The business case is not about "adding tracking" — it's about unlocking the analytics tools the team is already paying for. Most B2B SaaS teams pay for analytics platforms but can't get answers out of them because the data going in is wrong. Instrumentation fixes the input so the analytics investment pays off.
This skill sits outside the main telemetry lifecycle. It's the "convince" step that precedes everything else:
business-case → model → audit → design → guide → implement ← feature updates
Goal
Produce .telemetry/business-case.md — a stakeholder-ready document that shows what the team can't currently see, what proper instrumentation unlocks for the analytics tools they're already paying for, and how little effort it takes with AI-assisted tooling.
Prerequisites
None required. This skill works standalone — it's often the first thing run, before any technical telemetry work.
Optional context: If .telemetry/product.md exists, read it to make the case concrete and specific to the product. If it doesn't exist, gather enough context through conversation.
Process
1. Understand the Product
If .telemetry/product.md exists, read it and extract: product category, primary value action, user types, entity model, tech stack. Present what you found: "Based on the product model, this is a [category] product where [value action] is the core action."
If no product model exists, ask:
- "What does your product do, in one sentence?"
- "Who is this business case for?" (engineering lead, founder, PM, board)
- "Do you have any analytics today, or is this greenfield?"
Keep it to 2-3 questions. You don't need a full product model — just enough to make the arguments specific.
2. Identify Blind Spots
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.

product-tracking-business-case is a skill published in the GitHub repository Accoil/product-tracking-skills (39 stars, last pushed 6mo ago), licensed MIT. It adds 110 tokens to every session and 2,521 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 2026-08-30.
