Summary

The CI link checker (lychee) reports 4 broken file references in docs/CONTRIBUTING.md. All four errors stem from paths resolving to a non-existent docs/docs/ directory.

Broken links

1. docs/assets/connected_devtools.png — Malformed image syntax

Line: Under the "React DevTools" section
Current syntax:

![[](/docs/assets/connected_devtools.png)]

The extra outer brackets make this invalid Markdown. The file docs/assets/connected_devtools.png exists but the link doesn't resolve. Should be:

![connected devtools](./assets/connected_devtools.png)

2. docs/faq.md — File does not exist at referenced path

The "Need help?" section links to:

[FAQ](https://gemini-cli.com/docs/resources/faq)

This external URL is correct for the hosted site, but the link checker appears to be resolving a local file:// reference to docs/docs/faq.md, which does not exist. There is no faq.md anywhere in the docs/ directory. If a local-relative link is intended, it should point to the correct path or be excluded from the checker.

3. docs/integration-tests.md — Path resolved one level too deep

The "Integration tests" section links to:

[Integration Tests documentation](https://gemini-cli.com/docs/integration-tests)

The file docs/integration-tests.md exists at the top level of docs/. The checker resolves it to docs/docs/integration-tests.md which doesn't exist.

4. docs/sidebar.json — Path resolved one level too deep

The "Documentation structure" section links to:

[sidebar.json](https://github.com/google-gemini/gemini-cli/blob/main/docs/sidebar.json)

The file docs/sidebar.json exists. The checker resolves it to docs/docs/sidebar.json.

Root cause

The primary bug is #1 — the malformed image markdown with double brackets. For #2–#4, the link checker appears to be resolving paths relative to the file's location (docs/) and then prepending another docs/ prefix, creating the non-existent docs/docs/ base path. This may be a configuration issue in the lychee link checker setup (base URL or --base flag), or the external URLs are being incorrectly transformed into local file paths before checking.

Suggested fix

• docs: Add setup instructions for API key to README #1: Fix the image syntax from ![[](/docs/assets/connected_devtools.png)] to ![connected devtools](./assets/connected_devtools.png)
• Improve readability issues #2–Rename Tool.invalidParams to Tool.verifyParams #4: Investigate the link checker's base path configuration to determine why external/absolute URLs are being resolved as local files under docs/docs/. If intentional, add these paths to .lycheeignore.
