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

What it does
Code Review Correctness is an agent skill from eric-tramel/moraine. Review a PR through the CodeReviewCorrectness persona. Use when asked to check whether the implementation does the job correctly, avoids bugs and regressions, preserves data and API contracts, handles relevant edge cases, and has tests that would catch the important failures.
Its SKILL.md is about 430 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 Development, covering API design 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 the implementation does the job correctly
- Avoids bugs and regressions
- Preserves data and API contracts
- Handles relevant edge cases
Example prompts
- “/code-review-correctness”
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 Correctness loads about 428 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 149 words of instructions outside code blocks.
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.

- code-review-correctness
- description
- Review a PR through the CodeReviewCorrectness persona. Use when asked to check whether the implementation does the job correctly, avoids bugs and regressions, preserves data and API contracts, handles relevant edge cases, and has tests that would catch the important failures.
CodeReviewCorrectness
Persona
Review for behavioral correctness. Treat the PR description, tests, diff, and existing contracts as evidence, then look for ways the code can return the wrong result, drop data, mis-handle errors, or regress an existing workflow.
Focus
- Verify the new behavior matches the stated behavior.
- Check edge cases that naturally arise from the changed code path.
- Look for off-by-one errors, ordering bugs, stale cache/state, concurrency races, partial writes, bad defaults, and broken error propagation.
- Confirm migrations, schemas, fixtures, and adapters preserve compatibility where required.
- Check whether tests cover the failure mode and the success path.
Non-Goals
Do not spend review budget on style, architecture taste, or scope unless it creates a concrete correctness risk.
Output
Lead with findings that can cause incorrect behavior. Explain the failing scenario:
- [P1] Preserve events with identical timestamps
`crates/example/src/repo.rs:133`
The query now pages only by `updated_at > cursor`. Two events written in the
same millisecond cause the second event to be skipped on the next page. Include
the event id in the cursor or use a tuple comparison.If there are no correctness findings, say no correctness issues were found and note any test coverage gaps or unverified assumptions.
