What it does

Parallel Code Review is an agent skill from spencerpauly/awesome-cursor-skills. Run four parallel read-only subagents that each review the same diff from a different lens — security, performance, correctness, and readability — then merge findings into one report. Use before merging large or risky PRs.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Plain language and style rules, Subagents and Code review. The repository describes itself as: A curated list of awesome skills for Cursor. The licence is CC0-1.0.

When your agent uses it

  • Tasks that involve Plain language and style rules
  • Tasks that involve Subagents
  • Tasks that involve Code review

Example prompts

  • “/parallel-code-review”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Scope the change set
  2. Launch four parallel subagents
  3. Synthesize
  4. Optional — address findings

What it can do on your machine

Read from SKILL.md and the folder at commit 99cd265. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Parallel Code Review loads about 781 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~781

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Parallel Code Review

Use Cursor’s Task tool to run four explore (read-only) subagents at once. Each subagent only reads code and produces findings for one dimension. The main agent merges results into a single prioritized review — something only a multi-agent setup does efficiently.

When to use

  • Large diffs or refactors where a single pass misses categories.
  • Security-sensitive changes (auth, payments, parsing untrusted input).
  • Performance-sensitive paths (hot loops, N+1 queries, bundle entry points).

Workflow

1. Scope the change set

Prefer a concrete list of files for reviewers:

bash
git diff --name-only origin/main...HEAD

Or paste the PR link and let the main agent list changed files from the branch.

2. Launch four parallel subagents

Send one message with four Task invocations, each subagent_type: "explore" and readonly: true, with prompts like:

Security

Read-only review: SECURITY

Changed files:
<list>

Focus: injection (SQL, shell, XSS), authZ/authN gaps, secrets in code, unsafe deserialization, path traversal, SSRF, IDOR, dependency CVEs mentioned in diff.

Output:
- Critical / High / Medium / Low findings
- File:line and short fix recommendation
- "No issues" if nothing material

Performance

Read-only review: PERFORMANCE

Changed files:
<list>

Focus: N+1 queries, missing indexes, accidental O(n²) loops, bundle size impact, unnecessary re-renders, sync I/O on hot paths, unbounded caches.

Output: same severity + location format as above.

Correctness

Read-only review: CORRECTNESS

Changed files:
<list>

Focus: logic bugs, off-by-one, wrong edge cases, race conditions, error handling gaps, breaking API changes, test gaps for new behavior.

Output: same format.

Readability / maintainability

Read-only review: READABILITY

Changed files:
<list>

Focus: naming, duplication, abstraction boundaries, file size, unclear control flow, missing types/docs where they would prevent bugs.

Output: same format; prefer suggestions over nitpicks.
3. Synthesize

The main agent should:

  1. De-duplicate findings that appear in multiple dimensions (count once, worst severity).
  2. Order by severity, then by fix cost.
  3. Produce a short executive summary (5 bullets max) and a table or list of actionable items.
4. Optional — address findings

Fix in the main agent or spawn targeted non-readonly follow-up tasks only for approved items.

Notes

  • Keep prompts read-only so parallel runs never fight over writes.
  • If the diff is huge, split by directory and run four reviewers per directory in a second wave — do not cram unrelated megadiffs into one pass.
  • This complements human review; it does not replace compliance or security sign-off for regulated environments.
