## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - People ask chat agents about their work, and agents answer with Markdown links to tasks, runs and agents > - A chat agent sometimes writes a company link target with two leading slashes, for example `(//ACME/agents/<agentId>/runs/<runId>)` > - A browser reads that target as a link to a website whose host is `ACME`, so the link leaves the app and fails > - Task links still worked because the issue-reference parser finds `/issues/<id>` in any path, but run, approval and agent links did not > - This pull request renders such a link as the company path when its "host" is exactly a known company prefix, and tells chat agents to start link targets with one slash > - The benefit is that a person can open the run, approval or agent the agent linked ## Linked Issues or Issue Description No public issue exists. Related, but different: #17864 (same-origin absolute links). **What happened** In a chat-feature eval, a person asked what happened on a failed website attempt. The agent read the run, explained the failure and linked both runs as `[...](//ACME/agents/<agentId>/runs/<runId>)`. The rendered anchors kept `href="//ACME/..."`, which opens `http://acme/...`. The agent made the same `//` slip in an earlier attempt of the same case. **Expected behavior** A link to a company page opens that page in the app. A target like `//ACME/...`, where `ACME` is a company prefix, can only mean the company path `/ACME/...`. **Steps to reproduce** 1. Render Markdown `[Failed run](//ACME/agents/a/runs/r)` in a chat or comment while the viewer belongs to company prefix `ACME`. 2. Inspect the anchor. 3. See `href="//ACME/agents/a/runs/r"`. Click it, and the browser goes to host `acme`. ## What Changed - `ui/src/components/MarkdownBody.tsx`: add `companyPathFromProtocolRelativeHref`. When a link target is `//<host>...` and `<host>` is exactly one of the viewer's company prefixes, render it as `/<host>...` (query and fragment kept). Other protocol-relative links, absolute URLs and renders without known prefixes stay unchanged. - `server/src/services/agent-conversations.ts`: chat guidance now says to start each link target with exactly one slash, because a `//` target points to a different website. - Tests for both. ## Verification - `cd ui && pnpm exec vitest run src/components/MarkdownBody.test.tsx`: 69 passed. With the normalization removed, the new company-path test fails (red/green checked). - `server/src/__tests__/agent-conversations.test.ts` gets one added `toContain` assertion for the new guidance sentence. I could not run that suite locally in this worktree (its linked workspace packages are from an older checkout), so CI supplies it. - End to end: the change is cherry-picked onto a chat-eval case branch and run through the remote `runs-adapters.inspect-failed-run` eval. ## Risks - Low risk. The rewrite applies only when the protocol-relative host matches a company prefix the viewer already has, exactly and case-sensitively. A real single-label intranet host with the same uppercase name as a company prefix would now open the company path instead. Chat guidance already forbids invented hostnames for Paperclip links. - Guidance text grows by one sentence. ## Model Used - Anthropic Claude Opus 5.5 (`claude-opus-5-5`), tool use and code execution in Claude Code. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Editor dependency identity
Keep the root and workspace overrides for @codemirror/state,
@codemirror/view, and @lezer/common aligned. CodeMirror requires shared
extension identity, while Lezer parsers and syntax highlighters require shared
NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with
tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the
installed dependency graph and highlights sample code through the editor's real
language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
