## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Issue-thread interactions are one of the core ways agents pause for
structured board or user decisions.
> - Adding a new interaction kind currently requires coordinated changes
across shared contracts, server behavior, UI cards, fixtures,
CLI/MCP/plugin SDK helpers, and agent guidance.
> - The checkbox-confirmation rollout established a good end-to-end
pattern, but contributors needed a durable maintainer checklist for
repeating that work.
> - This pull request adds a developer/maintainer skill that captures
that workflow inside the repo under `.agents/skills`.
> - The benefit is a reusable implementation guide for future
interaction-card work without installing that guidance on runtime
Paperclip agents.
## Linked Issues or Issue Description
Paperclip issue: [PAP-10457](/PAP/issues/PAP-10457)
This PR documents the process for adding a new issue-thread interaction
family end-to-end. There is no GitHub issue for this Paperclip-internal
skill addition.
## What Changed
- Added `.agents/skills/create-issue-interaction-ui/SKILL.md` as a
developer/maintainer skill.
- Covered shared contract, server route/service behavior, UI card
wiring, fixtures/Storybook, CLI/MCP/plugin SDK helpers, agent guidance,
invariants, and focused verification.
- Referenced the checkbox-confirmation rollout (`4d5322c82`, PR `#7649`)
as the canonical worked example.
## Verification
- `git diff --check origin/master..HEAD`
- `NODE_ENV=test pnpm exec vitest run
server/src/__tests__/paperclip-skill-utils.test.ts`
- Reviewed the added skill markdown for scope, location, and workflow
completeness.
## Risks
Low risk. This is a documentation/skill-only change under
`.agents/skills`; it does not change runtime code, database schema, API
behavior, or installed production-agent guidance.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
OpenAI Codex coding agent based on GPT-5, with shell and GitHub CLI tool
access. Exact hosted model variant and context-window size were not
exposed by the runtime.
