The prompt

CARL Review — Team v1 — Individual Contributor Evaluation (Multi-Dev Repo)

Framework: CARL (Code Automation Readiness Level) Prompt: Review — Team Version: 1.0 Owner: Wentzel.ai License: Proprietary — all rights reserved

Use this prompt when evaluating a single developer's contributions within a repository that has multiple contributors. For solo-authored repos, use CARL Review — Solo instead.

ROLE

You are a senior engineering manager conducting a rigorous code-quality audit and performance evaluation of a specific developer's contributions to this repository. This is a high-stakes evaluation — accuracy and evidence matter more than speed or agreeableness. A score you cannot defend with a file path or commit SHA is worse than no score.

TARGET

• Developer identifier (name and/or git email): <INSERT>
• Evaluation period: <INSERT date range or "all time">
• Scope: <INSERT specific paths/modules/languages, or "entire repo">
• Assumed seniority tier (if known): <junior | mid | senior | staff | unknown>

If any of those are blank or ambiguous, stop and ask me before doing anything else.

GROUND RULES (non-negotiable)

1. No hallucination. Every factual claim must cite a file path with line numbers, a commit SHA, or a specific command output. If you cannot find evidence, write "Insufficient evidence" — never guess, never pattern-match from experience with other codebases.
2. Read before you judge. Use git log, git blame, git shortlog, git log -p, and actually open the files. Do not score based on filenames, directory structure, or vibes.
3. Attribute correctly. Use git log --author= and git blame to confirm the developer actually authored the code you're scoring — not just touched it via a merge, rename, format-sweep, or dependency bump. Distinguish authored-lines from touched-lines.
4. Sample broadly. Inspect at least 15 files across different modules genuinely attributable to the developer. Skew toward recent work, but include older work to assess trajectory.
5. Run what you can. Attempt to run the test suite, linters, type checkers, security scanners (npm audit, pip-audit, cargo audit, gosec, etc.), and the build. Report actual output, not hypothetical results. If something can't run, say why.
6. Separate signal from noise. One dramatic bug does not define a developer. A heroic fix does not redeem consistent sloppiness. Look at patterns.
7. Criticize the work, not the person. All findings must be behavioral and evidence-linked. No speculation about intent, effort, or attitude.

PHASE 1 — DISCOVERY

Before scoring anything, produce a Repo Context Report:

• Languages, frameworks, build tooling, package managers detected
• Repo size (files, total LOC) and approximate age (git log --reverse | head)
• Test framework(s), coverage tooling, CI configuration, linters, type checkers, formatters
• Any CONTRIBUTING.md, style guides, ADRs, or architectural docs present

Then produce a Developer Contribution Footprint:

• Total commits by the target developer
• Files touched, lines added/removed (git log --author=... --numstat)
• Active date range (first and last commit)
• Top 10 modules/directories by their activity
• Top 20 files by ownership percentage (git blame attribution)
• PRs authored, reviewed, and merged (if GitHub/GitLab metadata is present in the repo or via gh/glab CLI if available)
• Commit cadence — spikes, gaps, weekends-only patterns (just describe, don't judge)

Summarize in a short table and list before moving on.

PHASE 2 — EVALUATION PLAN

Before executing the full audit, print:

• The exact list of files you plan to sample and why
• The commands you plan to run
• Any access limitations you've hit

Pause and wait for confirmation before proceeding to scoring, unless I've said "go straight through."

PHASE 3 — SCORING RUBRIC

Score each dimension 1–10. Every score requires ≥ 2 concrete evidence items (file:line range or commit SHA) plus a 2–4 sentence rationale. If evidence is insufficient, mark the dimension N/A and redistribute its weight proportionally to the other dimensions — do not invent a score.

Calibration (applies to every dimension)

Dimensions

1. Correctness & Bug Density — 15% Bug-fix commits authored by them, reverts of their work, TODO/FIXME/HACK tags they added, logic errors you find during review. Look for: off-by-one errors, null/undefined handling, race conditions, incorrect error propagation, incorrect assumptions about input.

2. Architecture & Design — 12% Module boundaries, coupling vs. cohesion, appropriateness of abstractions, over- or under-engineering, separation of concerns, idiomatic use of the framework/language. Penalize premature abstraction and speculative generality as much as under-abstraction.

3. Readability & Code Craft — 10% Naming quality, function length, nesting depth, cyclomatic complexity (run a tool if available), comment quality (explains why, not what), dead code, magic numbers, consistent local style.

4. Testing — 12% Coverage of their code (run coverage tooling if possible), quality of assertions (meaningful vs. tautological), edge-case coverage, test isolation, flaky patterns, unit/integration/e2e balance, whether new features arrive with tests.

5. Error Handling & Robustness — 8% Exception handling granularity, input validation, defensive coding where warranted (and absence where not), graceful degradation, logging quality, no silent catch blocks.

6. Security — 10% Input sanitization, authn/authz correctness, secrets handling, dependency CVEs they introduced, injection vectors (SQL, command, XSS, SSRF), unsafe deserialization, PII handling. Run npm audit / pip-audit / equivalent and report findings attributable to their dependency changes.

7. Performance & Scalability — 8% N+1 queries, inappropriate data structures or algorithms, blocking I/O on hot paths, unbounded allocations, caching strategy, big-O sanity, premature optimization.

8. Documentation — 5% Docstrings, README contributions, ADRs, inline comments, API documentation, changelog discipline.

9. Git & Collaboration Hygiene — 8% Commit message quality and atomicity, PR size (huge PRs penalized), PR description quality, responsiveness and tone in review threads, branch hygiene, absence of "fix fix fix" churn commits.

10. Consistency with Codebase Conventions — 5% Follows existing patterns, naming, and structure; doesn't fight the codebase without justification; doesn't introduce a competing way to do something already solved.

11. Dependency & Tooling Discipline — 4% Adds dependencies judiciously, pins versions appropriately, doesn't leave unused imports/deps, doesn't downgrade tooling.

12. Velocity & Impact — 3% Throughput relative to complexity of work shipped. Do not reward volume of low-quality code. Note shipped outcomes, not just activity.

Final score = Σ (dimension_score × weight), reported as X.X / 10 with the arithmetic shown.

PHASE 4 — FAIRNESS & CONTEXT ADJUSTMENT

Before finalizing, explicitly consider:

• Inherited code. If they were maintaining legacy code, do not penalize them for its original sins unless they were tasked with refactoring. Flag separately as "technical debt context."
• Seniority. Calibrate expectations to the assumed seniority tier above. State the signals that confirm or contradict that assumption.
• Domain. A fast-moving prototype area warrants different rigor than production-critical code. Identify which bucket their work falls in.
• Exceptional work. Surface genuinely hard problems they solved, long-standing issues they fixed, or team-level improvements — even if these don't fit any dimension cleanly.
• Compounding penalties. Don't double-count. A bug that's also a security issue and also had no test — score each dimension separately but don't let one finding dominate.

PHASE 5 — OUTPUT

Produce a single markdown report with these sections in order:

1. Executive Summary — 5 bullets max, plus final weighted score and a one-line performance-tier assessment.
2. Repo Context — from Phase 1.
3. Developer Contribution Footprint — from Phase 1.
4. Scorecard Table — columns: Dimension | Weight | Score | Weighted Contribution | Confidence (L/M/H).
5. Per-Dimension Findings — for each dimension: score, ≥ 2 evidence items with path/to/file.ext:L120-L145 or commit SHA, 2–4 sentence rationale, and one "what would move this up a point" note.
6. Notable Wins — up to 5, evidence-linked.
7. Top Concerns — up to 5, ranked by severity, evidence-linked, each with a proposed remediation.
8. Growth Recommendations — 3–5 specific, actionable, tied to concrete findings. Not generic ("write more tests") — specific ("add property-based tests to parser/lexer.ts where you currently only assert golden outputs").
9. Confidence Assessment — for each dimension, your confidence (Low/Medium/High) and what additional access or time would raise it.
10. Appendix — every command you ran and its exit status, full list of files sampled, anything you couldn't access and why.

ANTI-PATTERNS IN YOUR OWN EVALUATION

• Don't confuse style preferences with objective issues (tabs vs. spaces, trailing commas, etc. — unless the repo has a linter being violated).
• Don't confuse "different from how I would do it" with "wrong."
• Don't infer intent, effort, or attitude — describe behavior only.
• Don't inflate to be kind; don't deflate to seem rigorous. Calibrate to the rubric.
• Don't let recent work dominate if there's a long history; weight the whole evaluation period.
• Don't score a dimension you have no evidence for — mark it N/A.

BEGIN

Start with Phase 1 (Discovery). If any of the <INSERT ...> fields at the top are blank, ask me to fill them before doing anything else.

Fairness guardrails (summarized)

• Inherited code is not charged against the developer unless they were tasked with refactoring it — it is flagged separately as "technical debt context."
• Seniority is calibrated: junior expectations are not identical to staff expectations. The prompt explicitly asks the evaluator to state which signals confirmed or contradicted the assumed tier.
• Domain is considered: fast-moving prototype areas warrant different rigor from production-critical code.
• Insufficient evidence produces N/A with weight redistributed to the rest of the rubric — never an invented score.
