Canonical Associations

Q: What is a Claude Code skill and how does the Canonical Associations skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Canonical Associations is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

The repeatable recipe for canonicalizing entity-to-entity relationships onto the ONE association system (platform.associations) and for canonicalizing Supabase table references post-2026-reorg. Use whenever a task touches a bespoke M2M junction table, an associate_*/get_*_associations/attach_*/tag_* RPC, FK-tag duplication (project_id/task_id columns used as "tagging"), a "list/attach/count things related to X" UI, or a bare .from("<moved-table>") that should be schema-qualified. Triggers on "associate", "attach", "link", "tag", "related to", "M2M", "junction table", "resources for this org/scope/project", "PGRST205 / 42703 table-not-found", or "canonicalize table ref". Holds the load-bearing boundary (associations vs iam.permissions/iam.memberships), the three recipes (replace-an-M2M, put-a-card-on-a-container, canonicalize-a-table-ref), the entity-token + registry rules, and the campaign backlog.

From the source SKILL.md

There is ONE way to relate two entities (content↔content, content↔container) in this app: an edge in platform.associations, written ONLY through associationsService (features/scopes/service/associationsService.ts), which is the sole caller of the assoc_ RPCs. Every bespoke M2M junction table, associate_/get_*_associations RPC, and FK-tag column used as a relationship is debt to migrate onto this edge. This skill is the exact recipe a subagent follows, one file at a time.

What this skill does

Canonical Associations is a community-contributed Claude Code skill in the databases sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/canonical-associations/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever a task touches a bespoke M2M junction table, an associate_*/get_*_associations/attach_*/tag_* RPC, FK-tag duplication (project_id/task_id columns used as "tagging"), a "list/attach/count things related to X" UI, or a bare .from("<moved-table>") that should be schema-qualified.

Who uses this skill

The Canonical Associations Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 186,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
