What it does
This skill reviews the diff against `HEAD~1` instead of whole files. The agent first calls `get_minimal_context_tool` and, if the graph is not ready, builds it with `build_or_update_graph_tool`. It then calls `detect_changes_tool` for risk-scored changed functions, test gaps and affected flows, and `get_review_context_tool` when it needs source snippets and review guidance such as untested functions or a wide blast radius.
For each untested high-risk function it confirms the gap with `query_graph_tool` using a tests_for pattern, and it moves from minimal to standard detail only for a high-risk item that stays unclear, avoiding whole-file loads. The report has a one-line summary, a low, medium or high risk rating based on blast radius, issues (bugs, missing tests, style), the impacted files and functions, and recommendations.
When your agent uses it
- Reviewing the changes in the latest commit before pushing
- Finding which functions a change affects and whether they have tests
- Keeping a code review short on tokens in a large repository
Example prompts
- “Review my last commit and tell me what it could break.”
- “Run a delta review and list any high-risk functions that have no tests.”
- “What is the blast radius of the changes I just made?”
Requirements
- The code-review-graph MCP tools such as `detect_changes_tool`
- A git repository with a previous commit to compare against

What it can do on your machine
Read from SKILL.md and the folder at commit 6b12d11. 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
Review Delta loads about 325 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 134 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.

Review Delta
Review only the changed code and its blast radius.
Steps
- Call
get_minimal_context_tool(task="review changes"). If it returnsstatus: not_ready, callbuild_or_update_graph_tool()and continue. - Call
detect_changes_tool(detail_level="minimal")for risk-scored changed functions, test gaps and affected flows. Changes come fromgit diffagainstHEAD~1; if the argument names a file, pass it inchanged_files. - Call
get_review_context_tool(detail_level="minimal")when you need source snippets for the changed areas andreview_guidance(untested functions, wide blast radius, inheritance changes). - For each untested high-risk function, confirm with
query_graph_tool(pattern="tests_for", target="<function>"). - Use
detail_level="standard"only for a high-risk item the minimal output leaves unclear. Do not load whole files unless a snippet is not enough.
Report
- Summary: one line
- Risk: low, medium or high, from the blast radius
- Issues: bugs, missing tests, style
- Blast radius: impacted files and functions
