Add job-hunt-skills plugin

[Jim-Coughlin]

Summary

Adds a single URL-reference entry to .claude-plugin/marketplace.json for job-hunt-skills, an open-source plugin for job hunters covering resume tailoring, cover letters, company research, interview prep, LinkedIn optimization, and reusable proof assets.

• Repo: https://github.com/Remotivated/job-hunt-skills
• License: MIT

• Category: productivity

Why URL-reference

The plugin is mature, self-contained, and actively maintained in its own repo. Following the pattern used by box, lseg, figma, postiz, and others rather than vendoring under partner-built/ so the plugin can be updated independently with SHA-bump PRs back here.

What the plugin does

• Resume / CV tailoring to specific roles (works with either format)
• Cover letter generation grounded in the user's actual experience
• Company research before applying
• Interview prep + interview coach with STAR+R story bank
• LinkedIn optimizer for headline, About, and experience sections
• Proof asset creator for reusable case studies
• Claim-check — distinctive guard against the most common LLM failure mode in this domain (fabricating experience the user doesn't have). Cross-references claims against source resume, story bank, and proof assets before output.

All artifacts are saved as local markdown the user owns under my-documents/.

Verification

• marketplace.json parses as valid JSON after the addition (verified with node -e "JSON.parse(...)")
• Plugin manifest at https://github.com/Remotivated/job-hunt-skills/blob/main/.claude-plugin/plugin.json matches the schema
• Plugin tested as a standalone marketplace via claude plugin marketplace add Remotivated/job-hunt-skills
• Pinned commit uses the modern skills/*/SKILL.md format throughout (no legacy flat-md commands/ files)

Happy to adjust any of the above based on review feedback.
