Security: Avoid committing .env files with credentials to version control.
The .env file contains hardcoded database credentials (postgres:password). Committing this file to version control poses a security risk, even with default credentials.

In backend/.env lines 1–1 the file contains hardcoded DB credentials
("postgres:password"), which must not be committed; add .env to .gitignore,
remove the committed secret from the repo (e.g., git rm --cached backend/.env
and commit) to stop tracking the file, rotate or replace the exposed password in
the database, create backend/.env.example with placeholder values and no real
secrets for documentation, and ensure future local secrets are stored only in a

Verify field length constraints are appropriate for domain data.
Line 7 specifies phone VARCHAR(15) and Line 8 specifies address VARCHAR(100). Phone numbers can exceed 15 characters when including country codes, extensions, or formatting. Addresses commonly exceed 100 characters for complete details. Consider increasing these limits or confirming the length constraints match your data requirements.

In
backend/prisma/migrations/20251111235207_add_recruitment_entities/migration.sql
around lines 7-8, the current columns use "phone" VARCHAR(15) and "address"
VARCHAR(100) which may be too short for international phone formats, extensions,
and long postal addresses; update these constraints to appropriate lengths
(e.g., phone to VARCHAR(30) or VARCHAR(50) and address to VARCHAR(255) or TEXT)
in the migration SQL, adjust any corresponding Prisma schema/type definitions to
match, and regenerate/apply the migration so the database and schema stay
consistent.

🧩 Analysis chain
Clarify the purpose and location of base-schema.sql.
This file is located in backend/prisma/migrations/ but does not follow Prisma's migration naming convention (TIMESTAMP_description/migration.sql). Additionally, it defines the same 12 tables as 20251111235207_add_recruitment_entities/migration.sql, which would cause a conflict if both are applied.
Possible issues:
- If this is meant to be a migration, it needs to be moved to a timestamped directory (e.g.,
20251110000000_base_schema/migration.sql) and applied before the recruitment entities migration. - If this is documentation or a reference schema, it should be moved outside the migrations directory to avoid confusion.
- If both files are in the PR, clarify which one should be applied—having duplicate CREATE TABLE statements will cause migration failures.
Recommend verifying the PR's migration sequence and removing or relocating this file accordingly.
I'll verify the concerns in this review comment by examining the migration files in the codebase.

Remove backend/prisma/migrations/base-schema.sql—it duplicates schema.prisma and doesn't belong in migrations.
The file at backend/prisma/migrations/base-schema.sql is a Prisma schema DSL file (not SQL), containing an identical copy of backend/prisma/schema.prisma. Prisma schema definitions belong in the root prisma/ directory, not in migrations/. This file should be deleted.
The actual SQL migration 20251111235207_add_recruitment_entities/migration.sql is correctly formatted and contains the proper CREATE TABLE statements—no conflict exists there.

Add missing onDelete specifications to match migration foreign key constraints.
Four relations lack onDelete specifications that are enforced by the migration SQL, creating a mismatch between database constraints and Prisma schema:
- Line 124:
interviewTyperelation should haveonDelete: Restrict(migration line 239:ON DELETE RESTRICT) - Line 155:
interviewFlowrelation should haveonDelete: Restrict(migration line 245:ON DELETE RESTRICT) - Line 197:
employeerelation should haveonDelete: SetNull(migration line 260:ON DELETE SET NULL) - Line 198:
interviewSteprelation should haveonDelete: Restrict(migration line 257:ON DELETE RESTRICT)
Without these specifications, Prisma won't enforce or properly handle these database constraints, potentially causing unexpected errors at runtime.

In backend/prisma/schema.prisma around lines 124, 155, 197-198, add the missing
onDelete specifications to the relation fields to match the migration SQL: for
the InterviewStep model at line 124 set the interviewType relation to use
onDelete: Restrict; for the Position model at line 155 set the interviewFlow
relation to use onDelete: Restrict; for the Interview model at line 197 set the
employee relation to use onDelete: SetNull and at line 198 set the interviewStep
relation to use onDelete: Restrict. Update the relation attribute syntax
accordingly (e.g. @relation(fields: [...], references: [...], onDelete:
Restrict/SetNull)) so the Prisma schema matches the DB constraints.

Add @db.Text annotations to String fields that are TEXT in the migration.
Multiple String fields are defined as TEXT in the migration SQL but lack @db.Text annotations in the schema. Without these, Prisma defaults to VARCHAR, causing a mismatch:
- Position.description (line 137, migration line 113)
- Position.jobDescription (line 141, migration line 117)
- Position.requirements (line 142, migration line 118)
- Position.responsibilities (line 143, migration line 119)
- Position.benefits (line 147, migration line 123)
- Position.companyDescription (line 148, migration line 124)
- Application.notes (line 170, migration line 140)
- Interview.notes (line 193, migration line 156)
Subsequent runs of prisma db push might attempt to alter these column types from TEXT to VARCHAR.

🤖 Prompt for AI Agents
In backend/prisma/schema.prisma around line 137 (and also lines 141-143,
147-148, 170, 193), several String fields are TEXT in the migration but lack the
@db.Text annotation causing Prisma to treat them as VARCHAR; update the
Position, Application, and Interview models to add @db.Text to the following
fields: Position.description (line 137), Position.jobDescription (141),
Position.requirements (142), Position.responsibilities (143), Position.benefits
(147), Position.companyDescription (148), Application.notes (170), and
Interview.notes (193); modify each field declaration to append @db.Text so the
schema matches the migration and prevents prisma db push from trying to change
types.

1-312: Verify the filename aligns with module format requirements.The PR objectives reference a required file named
prompts-iniciales.md, but this file is namedprompts.md. Ensure the filename matches the expected module format. If the naming convention is flexible, this can be ignored; otherwise, consider renaming toprompts-iniciales.md.
5-312: Excellent comprehensive guide addressing the module requirement.This file fulfills the PR objective's requirement for prompts documentation. The five-stage workflow systematically guides users from ERD interpretation through database optimization, with each stage containing clear objectives, actionable LLM prompts, and relevant examples. Stage 3 correctly integrates with the existing Prisma schema style, and the embedded Mermaid diagrams ensure visual consistency across workflows. The guide aligns well with the recruitment domain model already defined in the schema and addresses the normalization, indexing, and scalability concerns flagged by the previous reviewer.
