  • The user says work with engineering
  • SKILL.md covers Is this the right thing?, Step 1 — Preflight (before the…, Step 2 — Discovery with eng… and Step 3 — What engineering…, plus 7 more sections

What it does

Eng Design Collab is an agent skill from andreaskelm/pm-brain. Partner effectively with engineering and design — feasibility and scope negotiation, tech debt tradeoffs, design reviews, discovery with builders, and PRD handoffs that don't get thrown away. Covers what eng needs, what design needs, how to frame debt, and language for hard conversations. Use when the user says "work with engineering", "design review", "tech debt negotiation", "is this feasible", "PRD handoff", "get eng bought in", "design partnership", "scope negotiation", or is stuck between product intent and…

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/criteria.md` and `references/handoff.md`).

It sits in Product & Project Management, covering PRD writing, Design review and critique and Technical debt. The repository describes itself as: AI-powered product management thinking & operating system. Playbooks, guides, templates, and frameworks that bridge PM theory to daily execution.

When your agent uses it

  • The user says work with engineering
  • Tech debt negotiation
  • Is this feasible
  • Get eng bought in

Example prompts

  • “work with engineering”
  • “design review”
  • “tech debt negotiation”
  • “/eng-design-collab”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Preflight (before the room)
  2. Discovery with eng and design (before the PRD is sacred)
  3. What engineering needs from you
  4. What design needs from you
  5. Tech debt and scope negotiation
  6. PRD handoff that sticks

What it can do on your machine

Read from SKILL.md and the folder at commit 38696ac. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Eng Design Collab loads about 2.1k tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 138 tokens; SKILL.md has 1,186 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~138
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,186 words (~2,150 tokens).

“The handoff isn't a meeting where you read the PRD aloud. It's the moment your thinking meets people who have to live inside the constraints you waved past. The failure mode I see: PM shows up with a polished doc…”
