Summary

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating spec/PRD asked for?). Use when the user wants to review a bran

1	Two-axis review of the diff between `HEAD` and a fixed point the user supplies:
2
3	- Standards — does the code conform to this repo's documented coding standards?
4	- Spec — does the code faithfully implement the originating spec / PRD?
5
6	The two axes are reviewed in isolation so they don't pollute each other, then aggregated side by side.
7
8	## Process
9
10	### 1. Pin the fixed point
11
12	Whatever the user said is the fixed point — a commit SHA, branch name, tag, `main`, `HEAD~5`, etc. If they didn't specify one, ask for it.
13
14	Capture the diff command once: `git diff <fixed-point>...HEAD` (three-dot, so the comparison is against the merge-base). Also note the list of commits via `git log <fixed-point>..HEAD --oneline`.
15
16	Before going further, confirm the fixed point resolves (`git rev-parse <fixed-point>`) and the diff is non-empty. A bad ref or empty diff should fail here — not inside the two reviews.
17
18	### 2. Identify the spec source
19
20	Look for the originating spec, in this order:
21
22	1. A path the user passed as an argument.
23	2. A spec under `.plan/` — typically `.plan/<slug>/spec.md`, matching the branch name or feature.
24	3. A PRD/spec file elsewhere in the repo (`docs/`, `specs/`, or similar) matching the branch name or feature.
25	4. Issue references in the commit messages (`#123`, `Closes #45`, etc.) — if the environment has a way to fetch them (e.g. the repo host's CLI), fetch the referenced issue.
26	5. If nothing is found, ask the user where the spec is. If they say there isn't one, the Spec axis will skip and report "no spec available".
27
28	### 3. Identify the standards sources
29
30	Anything in the repo that documents how code should be written, such as `CODING_STANDARDS.md` or `CONTRIBUTING.md`.
31
32	On top of whatever the repo documents, the Standards axis always carries the smell baseline below — a fixed set of Fowler code smells (_Refactoring_, ch.3) that applies even when a repo documents nothing. Three rules bind it:
33
34	- The repo overrides. A documented repo standard always wins; where it endorses something the baseline would flag, suppress the smell.
35	- The language's paradigm applies. Skip smells that don't fit the language being reviewed — e.g. Refused Bequest in a language without inheritance, Feature Envy where there are no objects to envy.
36	- Always a judgement call. Each smell is a labelled heuristic ("possible Feature Envy"), never a hard violation — and, like any standard here, skip anything tooling already enforces.
37
38	Each smell reads what it is → how to fix; match it against the diff:
39
40	- Mysterious Name — a function, variable, or type whose name doesn't reveal what it does or holds. → rename it; if no honest name comes, the design's murky.
41	- Duplicated Code — the same logic shape appears in more than one hunk or file in the change. → extract the shared shape, call it from both.
42	- Feature Envy — a method that reaches into another object's data more than its own. → move the method onto the data it envies.
43	- Data Clumps — the same few fields or params keep travelling together (a type wanting to be born). → bundle them into one type, pass that.
44	- Primitive Obsession — a primitive or string standing in for a domain concept that deserves its own type. → give the concept its own small type.
45	- Repeated Switches — the same `switch`/`if`-cascade/pattern-match on the same type recurs across the change. → replace with polymorphism, a dispatch table, or one match site both callers share.
46	- Shotgun Surgery — one logical change forces scattered edits across many files in the diff. → gather what changes together into one module.
47	- Divergent Change — one file or module is edited for several unrelated reasons. → split so each module changes for one reason.
48	- Speculative Generality — abstraction, parameters, or hooks added for needs the spec doesn't have. → delete it; inline back until a real need shows.
49	- Message Chains — long `a.b().c().d()` navigation the caller shouldn't depend on. → hide the walk behind one method on the first object.
50	- Middle Man — a class or function that mostly just delegates onward. → cut it, call the real target direct.
51	- Refused Bequest — a subclass or implementer that ignores or overrides most of what it inherits. → drop the inheritance, use composition.
52
53	### 4. Run both reviews in isolation
54
55	If your environment supports spawning subagents, send a single message with two subagent calls (use a general-purpose subagent for both) so the axes run in parallel with isolated context.
56
57	Otherwise, run the two axes as sequential, self-contained passes in this s
