Get Advice from Top‑Tier P7‑P9 Engineers with My Open‑Source AI Skills

The author, an AI expert and agent engineer, observed that people at different seniority levels focus on different aspects of the same problem, and therefore created three open‑source “Skill” packages that encode the capability models of P7 (team‑level expert), P8 (domain‑level leader) and P9 (business/organization director) from leading tech companies.

Each Skill can be queried by sending a description of a dilemma, plan, or project; the underlying AI then responds from the perspective of the corresponding senior role, offering evaluation and suggestions.

The capability dimensions captured in the Skills include common titles, core abilities, impact scope, technical requirements, business understanding, organizational collaboration, and typical deliverables. For example:

P7 – titles: Technical/Product Expert; core abilities: solving complex problems, owning projects, leading small teams; impact: single team/module; technical depth required; business focus on delivery.

P8 – titles: Senior Expert/Architect; core abilities: domain planning, architectural decisions, department‑level influence; impact: an entire business or technical domain; breadth plus depth.

P9 – titles: Senior Expert/Director; core abilities: business judgment, strategic planning, cross‑domain integration; impact: multiple teams and business lines, shaping decisions.

The Skills are hosted on GitHub under the repository chujianyun/skills. Installation is done by providing the Skill link to an agent tool such as Qoder Work, which follows prompts to set it up.

Usage examples show how the P7 Skill can point out common pitfalls—e.g., start with high‑value material and solve three real problems before scaling the system—while the P8 Skill offers a different, higher‑level viewpoint. Users can also include their own seniority level in the query to help the AI tailor advice.

Practical advice includes avoiding premature adoption of heavy components like vector stores or complex permission systems; instead, begin with Markdown, Git, rg, and Obsidian/Codex, and only consider more advanced search solutions once the knowledge base grows substantially.

Overall, the open‑source Skills provide a higher‑level reference point that can reveal blind spots in personal or team projects, supporting tasks such as project planning, technical architecture, product evaluation, knowledge‑base construction, and personal growth reviews.
