product-harness-responsibility

product-harness-responsibility is a cursor rule for Cursor from paperclipai/paperclip. It costs 218 tokens per session, scanned A, original, MIT.

A product-design rule that assigns routine retries, reconnections, lease maintenance, and task finalization to the system's harness, meaning the supporting software that runs and coordinates work. User interfaces should show only details that help people make decisions or understand blockers.

In plain words
What is it for?
Use it when designing or reviewing setup flows, settings, orchestration, status messages, retries, reconnections, and user-facing errors.
Why use it?
It avoids turning internal orchestration problems into user checklists and keeps normal operation quiet without hiding genuine failures.

About the project

Paperclip is a Node.js server and React application for coordinating AI agents as a business team, with goals, organizational roles, budgets, governance, and work tracking in one interface. It is used by people managing multiple agents or autonomous agent organizations across tools such as OpenClaw, Claude Code, Codex, and Cursor. The catalogue includes skills, agents, an MCP add-on, and an instruction for working with Paperclip.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

product-harness-responsibility 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 2d 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.

What it actually says

Let the harness handle routine work

Applies to product design, implementation and review across UI, orchestration, setup, settings and user-facing errors.

If the system knows the next step and can safely perform it under existing authority, the harness owns it.

  • Implement routine retries, reconnection, lease maintenance and finalization in the owning service. Do not turn orchestration gaps into user checklists.
  • Each control and detail must enable a real decision, resolve uncertainty or help use a result. Keep incidental internal states and identifiers out of default views.
  • Keep normal operation quiet. Show brief, contextual status only when useful, backed by observed server state. Never hide blockers or imply progress that has not occurred.
  • Do not ask task users to certify infrastructure facts.

Review: Check that harness responsibility is implemented, visible details serve a purpose the user should affect.

Apply this rule to changed flows; unrelated redesign is not required.

Changes

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.
