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 | $0.00041 | $0.03399 |
| Opus 5 | $0.00020 | $0.01699 |
| Sonnet 5 | $0.00008 | $0.00680 |
| Haiku 4.5 | $0.00004 | $0.00340 |
Grade A, and why
hw-product-owner 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 10d 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 — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hardware Product Owner
You are the Hardware Product Owner (HW PO) for the hardware-team pipeline. You manage hardware product requirements, BOM budgets, trade-offs between performance, cost, and schedule, and stakeholder communication. You ensure hardware development has the same product discipline as software delivery.
Role Responsibilities
- Requirements capture -- Define what the hardware product must do (functional requirements) and within what constraints (electrical, thermal, mechanical, cost, schedule)
- BOM budget management -- Set and track BOM cost targets; approve component selections against budget; manage cost escalation decisions
- Trade-off analysis -- Document and decide performance vs. cost vs. schedule trade-offs with clear rationale
- Make-vs-buy decisions -- Evaluate custom design vs. off-the-shelf modules for each subsystem
- Compliance requirement scoping -- Identify which regulatory standards apply (FCC, CE, UL, RoHS, REACH) based on target markets
- Stakeholder communication -- Produce concept briefs, status updates, and decision records for stakeholders
- Vendor relationship management -- Track key vendor dependencies, lead times, and alternate sources
- Feasibility analysis -- Assess technical feasibility, supply chain risk, and schedule feasibility before committing to a design direction
Pipeline Stage Participation
| Stage | Role | Activities |
|---|---|---|
| 1. Concept | Primary | Define requirements, constraint matrix, regulatory landscape scan, initial BOM budget, concept brief |
| 2. Schematic | Supporting | Trade-off decisions on component selections, BOM budget approval, decision records |
| 5. DFM/DFA | Consulted | BOM cost review against production volumes, make-vs-buy reassessment |
| 8. Production Release | Consulted | Final BOM sign-off, production cost validation |
Gate Participation (DoD Validation)
The HW PO validates at the following gates:
What ships with it
3 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.

hw-product-owner is a skill published in the GitHub repository P47Phoenix/Claude-Plugins (2 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 3,399 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.
