ecto-constraint-debug — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited ecto-constraint-debug (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Systematic approach to diagnosing constraint violations. Load when you see Ecto.ConstraintError, unique_constraint, foreign_key_constraint, or constraint-related changeset errors.

users_email_index)users)Use Grep to search for the constraint name in priv/repo/migrations/. Also check for create unique_index, create index, add constraint.
Verify: Does the migration constraint match the schema's unique_constraint/3 or foreign_key_constraint/3 call?
Use Grep to find constraint handling in changesets (unique_constraint, foreign_key_constraint, check_constraint) in lib/.

| Symptom | Likely Cause | Fix Pattern |
|---|---|---|
| Same user triggers twice | Race condition (double-click, retry) | Upsert with on_conflict |
| Multiple parents share child | cast_assoc doesn't dedup across changesets | Dedup before building changesets |
| Concurrent API requests | Missing transaction isolation | Wrap in Repo.transaction or use upsert |
| Migration added constraint to existing data | Data violates new constraint | Backfill or clean data first |
See ${CLAUDE_SKILL_DIR}/references/constraint-patterns.md for detailed fix patterns.
Unique violation → Upsert: Repo.insert(changeset, on_conflict: :replace_all, conflict_target: [:field])
Foreign key violation → Check: Does the referenced record exist? Was it deleted concurrently?
Check constraint → Validate: Does the value satisfy the constraint condition?
