feat: add Gram agent skills for Claude Code

[simplesagar]

Summary

• Adds a distributable Claude Code plugin (skills/) with 6 user-facing skills that guide Gram end-users through CLI workflows: deploying OpenAPI specs, deploying functions, installing MCP servers, checking deployment status, and authoring functions with the SDK
• Adds mise run skills:update task that syncs skills against current CLI help output, validates structure (frontmatter, cross-refs, line counts), and supports version bumping
• Updates CLAUDE.md with a pointer to the new user-facing skills directory

Skills included

Skill	Purpose
gram-context	Foundation — CLI reference, auth, config file format
deploy-openapi	Deploy OpenAPI v3 specs (stage+push and upload flows)
deploy-functions	Deploy Gram Functions zip files
install-mcp-server	Install MCP servers in Claude Code, Claude Desktop, Cursor, Gemini CLI
check-deployment-status	Monitor and debug deployments
write-gram-function	Author functions with @gram-ai/functions SDK

Update task

mise run skills:update                  # validate skills against CLI
mise run skills:update --bump patch     # validate + bump plugin version

Test plan

• mise run skills:update passes with only 2 acceptable warnings
• All 6 SKILL.md files have valid YAML frontmatter with trigger phrases
• Cross-references between skills are consistent
• plugin.json skills path resolves correctly
• All skills under 500 lines
• Install plugin in Claude Code and verify skill activation on trigger phrases

Might I suggest you add a section here that explains what gram is?

Idk how you're installing this but I think this has to be at the repo root as a second a second plugin (living along side Chase's hooks plugin)

Luckily you can pattern match off that skill.

Might want to change the top-level directory to "gram-claude-plugin" and then reference it from the skills file
