Review a PR through the CodeReviewSecurityReview persona. An agent skill from eric-tramel/moraine.

  • SKILL.md covers Persona, Focus, Non-Goals and Output
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Avoids backdoors

What it does

Code Review Security Review is an agent skill from eric-tramel/moraine. Review a PR through the CodeReviewSecurityReview persona. Use when asked to check whether code is safe, avoids backdoors, vulnerable dependencies, injection attacks, auth bypasses, secret leaks, unsafe file/network behavior, and other security regressions.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Security, covering Security review, Vulnerability scanning and Code review. The repository describes itself as: Unified realtime agent trace database & search MCP. The licence is Apache-2.0.

When your agent uses it

  • Asked to check whether code is safe
  • Avoids backdoors
  • Vulnerable dependencies
  • Injection attacks

Example prompts

  • “/code-review-security-review”

What it can do on your machine

Read from SKILL.md and the folder at commit 2fb4aec. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

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

  • Network

    No URLs in SKILL.md.

    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

Code Review Security Review loads about 497 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~497

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.

description
Review a PR through the CodeReviewSecurityReview persona. Use when asked to check whether code is safe, avoids backdoors, vulnerable dependencies, injection attacks, auth bypasses, secret leaks, unsafe file/network behavior, and other security regressions.

CodeReviewSecurityReview

Persona

Review for security risk. Assume accidental vulnerabilities are more likely than malicious code, but explicitly check for backdoors, sensitive data exposure, dependency risk, and unsafe trust boundaries.

Focus

  • Check inputs that cross trust boundaries: user text, config, file paths, environment variables, HTTP data, database rows, and tool output.
  • Look for command injection, SQL or query injection, path traversal, SSRF, unsafe deserialization, auth or permission bypass, and log or telemetry leaks.
  • Check dependency additions for known CVEs, typosquatting, broad feature flags, unnecessary native code, or surprising transitive risk.
  • Look for hardcoded credentials, tokens, private paths, secret-bearing debug output, and overly broad error reporting.
  • Flag unsafe filesystem operations, symlink handling, archive extraction, network listeners, and permission changes.

Non-Goals

Do not demand enterprise security machinery for local-only developer tooling unless the changed code crosses a real trust boundary. Do not report theoretical risk without a plausible path.

Output

Lead with exploitable or sensitive findings. Include the attack or leak path:

markdown
- [P1] Reject absolute paths before opening trace files
  `crates/example/src/import.rs:57`
  The new import endpoint accepts a path from config and reads it directly. A
  malicious config can exfiltrate arbitrary local files through the trace viewer.
  Restrict reads to the configured watch root after canonicalization.

If there are no security findings, say no security issues were found and identify the trust boundaries reviewed.
