Review Response Workflow

Batch-process all pending review comments on a PR in a single pass.

Step 1: Identify the PR

If a PR number was provided as an argument, use it. Otherwise, detect the current PR:

gh pr view --json number,url,headRefName --jq '.number'

Step 2: Fetch all pending review comments

gh api repos/{owner}/{repo}/pulls/{number}/comments --jq '.[] | select(.position != null) | {id, path, line: .original_line, body, user: .user.login}'

Also check for PR review threads with unresolved status:

gh api graphql -f query='{ repository(owner:"{owner}", name:"{repo}") { pullRequest(number:{number}) { reviewThreads(first:100) { nodes { isResolved comments(first:10) { nodes { body author { login } path line } } } } } } }'

Step 3: Route comments by reviewer type

• Copilot comments (author is copilot or github-actions): Invoke /copilot-review {PR number} to handle these — it fetches, evaluates, applies, and replies automatically.
• Human reviewer comments: Process each one individually in the steps below.

Step 4: Apply fixes for human reviewer comments

For each unresolved human review comment:

1. Locate the code with Serena, not bare Read:

   • mcp__serena__get_symbols_overview on the referenced file to see what's there.
   • mcp__serena__find_symbol (with include_body=true only when you need the body) to jump straight to the function/method/struct the comment is about. Use name_path_pattern like Args/cat_rowskey rather than scanning the whole file.
   • mcp__serena__find_referencing_symbols before changing any signature, return type, or removing a symbol — confirms the blast radius across the codebase.
   • Only fall back to Read when the comment is about plain text (docs, comments, USAGE strings) that has no symbolic structure, or when Serena returns empty.

2. Verify library/API claims with Context7 before agreeing or disagreeing:

   • If the reviewer asserts behavior of a third-party crate/library/SDK (e.g., "the csv crate's byte_headers() consumes the row", "tokio's spawn_blocking returns JoinHandle"), call mcp__context7__resolve-library-id then mcp__context7__query-docs to confirm before acting. Reviewer claims are not always correct; library behavior can change between versions.
   • Skip Context7 only when the comment is purely about local code (project-internal logic, naming, project conventions).

3. Apply the fix using Edit (preferred) or mcp__serena__replace_symbol_body for whole-symbol rewrites.

Step 5: Verification gate

Before committing, verify accuracy of all changes:

• If any change touches documentation that references counts (tool counts, command counts, feature lists): explicitly list each item by name, then count the list. Never state a number without showing the enumeration.
• If any change references file paths, confirm they exist (Bash with ls/test -f).
• If any change references a symbol (function, struct, method, constant), use mcp__serena__find_symbol to confirm it exists at the path you wrote — not Grep. A grep hit on the name is not proof the symbol resolves there.
• If any change references CLI flags or options, verify they exist in the source or --help output.
• If any change relies on third-party library behavior, the relevant Context7 query from Step 4 must already be in this conversation. If you're verifying after the fact, run it now — do not commit on unverified library assumptions.

Step 6: Run tests

Run the appropriate test suite based on what was changed:

• Rust source (.rs): cargo test -F all_features
• MCP server (.ts): npm test (from .claude/skills/)
• Specific command: cargo t {command_name} -F all_features

Step 7: Commit

git add <changed files>
git commit -m "address review: <concise summary of fixes>"

Step 8: Reply to resolved comments

For each comment that was addressed, reply via the GitHub API:

gh api repos/{owner}/{repo}/pulls/{number}/comments/{comment_id}/replies -f body="Fixed: <what was changed>"

Step 9: Report summary

Output a summary table:

Metric	Value
Comments addressed	N
Copilot (via /copilot-review)	N
Human reviewer	N
Tests	passed/failed/skipped
Commit	<hash>
