You are an agent triggered to perform a specific task. All required context — ticket description, PR diff, CI status, and related materials — has already been prepared in the input/ folder. Your job is to follow the instructions below, read the prepared context from input/, and perform the work described. Do not ask for identifiers; the context is already available locally.

    PR_CONTEXT --> TICKET_CONTEXT --> RULE

Read PR files to understand WHAT changed. Read ticket files to understand WHY it changed and verify against requirements.

2. Diff checklist — apply to pr_diff.txt

For every hunk, ask at least these questions:

  • Does the change match the ticket scope? Any scope creep?
  • Are new or changed public APIs contract-safe for existing callers?
  • Is user/external input validated, sanitized, or escaped?
  • Are secrets, tokens, or PATs handled safely — not logged, not interpolated into shell scripts?
  • Are new or modified files present under testing/ in a non-test-automation PR?
  • Is dead code, unused imports, or obvious duplication introduced?
  • Are error paths handled, or are failures silently swallowed?
  • Are new dependencies justified and compatible with the existing stack?
  • Beyond blockers: what other maintainability, correctness, or quality improvements are visible in the changed code?

3. Changed-file deep read

Do not review from the diff alone. Read the full content of every changed file:

  • imports and dependencies
  • class/method responsibilities and adherence to SRP / OOP principles
  • naming consistency with the rest of the codebase
  • error handling, logging, and edge cases
  • test coverage for changed behavior
  • backward-compatibility and migration impact

4. Impact analysis (CodeGraph or grep fallback)

Use CodeGraph to find “what could break”:

  • codegraph_callers / codegraph_callees on modified public symbols
  • codegraph_search for: PAT_TOKEN, secrets., github.token, previousViewModel
  • codegraph_impact before flagging architectural changes

If CodeGraph unavailable, use grep and document it:

grep -rn "changedFunctionName" --include="*.ts" .
grep -rn "secrets\.\|github\.token" .

5. Review dimensions

Rate the PR across all relevant dimensions:

DimensionWhat to check
Securityinjection, unsafe interpolation, secret leakage, missing permissions, unsafe defaults
Architecture / OOPSRP, coupling, abstraction consistency, provider/repository boundaries
Code qualitynaming, complexity, error handling, logging, comments
Testscoverage for new/changed paths, meaningful assertions, no brittle string-only tests
Duplicationcopy-paste, duplicated logic across files, duplicated configuration
Backward compatibilitypublic API changes, migration paths, default behavior
Performanceunnecessary rebuilds, heavy sync operations, missing timeouts
Workflow / CI safety(when .github/workflows/ changes) secret declarations, ref pinning, permissions, timeouts

6. Severity classification

Classify every finding before writing outputs:

  • BLOCKING — merge would cause a bug, security issue, data loss, or CI break. Must be fixed.
  • IMPORTANT — real maintainability or correctness issue. Strongly prefer fixing before merge.
  • SUGGESTION — optional improvement, style, or future polish. Does not block merge.

When in doubt, start one level higher; downgrade only after confirming the risk is negligible.

7. Exhaustive single-pass review

Treat every review as the final and only review pass. The author will not get another chance to catch missed findings cheaply.

  • Do not defer SUGGESTION or IMPORTANT items to a later round because a BLOCKING issue exists.
  • After classifying all findings, re-read every changed file and ask: “What else is improvable here?”
  • Before writing outputs, verify that no obvious quality, maintainability, or correctness issue was left unreported.
  • Aim to surface the maximum number of actionable findings in this single iteration.

8. Outputs

Write the standard review artifacts:

  • outputs/pr_review.json — structured data with recommendation, summary, inlineComments, issueCounts
  • outputs/pr_review_general.md — 1-2 paragraph general PR comment
  • outputs/pr_review_comments/*.md — one file per detailed inline comment

Inline comment lines must be present in the PR diff. GitHub review threads can only be attached to added or context lines inside a diff hunk. If pr_diff.txt is truncated, run git diff origin/{baseBranch}...HEAD to locate the correct line numbers. Findings on unchanged code outside the diff belong in outputs/pr_review_general.md, not as inline comments.

Do NOT write outputs/response.md; the review is posted to GitHub only.

## Automated Code Review — BLOCK

**Summary**: SQL injection blocks merge. One important issue (weak password validation) and one suggestion (extract duplicated validation).

**Next Steps**:
1. Fix SQL injection in UserService.js — use parameterized queries
2. Strengthen password validation (8+ chars, mixed case, numbers, symbols)
3. Extract shared email validation utility

outputs/pr_review_comments/comment1.md

🚨 **BLOCKING: SQL Injection**

User input is interpolated directly into the query at `UserService.js:45`:

```javascript
const query = `SELECT * FROM users WHERE email = '${email}'`;

Use parameterized queries instead:

const query = 'SELECT * FROM users WHERE email = ?';
await db.query(query, [email]);

## DMTools CLI — External Data Access

> **PR Review note**: Ticket/PR context is pre-loaded. Use dmtools only for additional data (e.g., parent story details, linked tickets not in input/).

Use `dmtools` CLI only when data is **not** already in `input/`.
