Complexity reduction, measured
Reduce cognitive complexity and duplication in a subsystem or in a diff. Every claim is a number from a tool. Every edit is a pure move: behaviour identical, only the shape changes.
Cognitive complexity at or above 15 for one function marks a potential problem, in every language below. It is a threshold to report, not a rule to enforce.
1. Tools
Pick the tool by language. Never report a number you did not measure.
Java: pmd
pmd (Homebrew: brew install pmd). Two of its commands matter.
pmd check -R <skill dir>/pmd-complexity.xml --file-list <list> -f csv -r <out>.csv --no-progress
pmd cpd --minimum-tokens 45 --language java --file-list <list> --format csv
pmd-complexity.xml beside this file enables CognitiveComplexity (report level 15),
CyclomaticComplexity and NPathComplexity, and nothing else.
Rust: rust-code-analysis-cli
Install it with cargo. --locked is required: without it, v0.0.25 fails to compile, because
the dependency graph resolves two different tree-sitter versions (0.20 expected, 0.27 found).
cargo install --locked rust-code-analysis-cli
Measure, then pull out every function at or above the threshold:
rust-code-analysis-cli -m -p <path> -O json --pr > <out>.json
Scores live in a recursive spaces[] tree, at metrics.cognitive.sum. A flat filter misses
nested functions and closures, so recurse:
jq -r '
def scores($file):
(if .kind == "function" then
"\($file):\(.start_line)\t\(.name)\t\(.metrics.cognitive.sum)"
else empty end),
(.spaces[]? | scores($file));
. as $r | $r | scores($r.name)' <out>.json \
| awk -F'\t' '$3 >= 15'
-p takes a file or a directory. For a list of files, repeat the flag — -p a.rs -p b.rs.
A space-separated list after one -p fails, which is exactly the case diff mode hands you. Pass
-I '*.rs' to include and -X to exclude by glob.
There is no cpd equivalent here, so duplication in Rust is a read, not a measurement. Say so
rather than implying a tool checked it.
Reading the metric
Cognitive Complexity is the SonarSource metric. It charges for nesting depth, so a triply-nested condition costs far more than three flat ones. That is why extraction of a deeply nested region buys more than extraction of a long flat one, and it is why you always attack the deepest nesting first.
cpd finds only near-identical token runs. It cannot see a repeated decision whose branches
differ. Read for that yourself; it is usually the more valuable finding.
2. Pick the mode, then define the file set
Two modes. Ask the user which one if the request does not say.
| Mode | File set | Ends at |
|---|---|---|
| Subsystem (default) | The files a feature owns | Section 4, unless --refactor |
| Diff | The files a diff or PR changes | Section 4, unless --refactor |
The mode picks the file set. --refactor decides whether anything gets edited, and it is the
only thing that does.
Diff mode
Score whole changed files, not only the functions the diff touched. A small edit can push a neighbouring function past the threshold, and touched-only scoring hides that. Mark which findings the diff introduced and which were already there, so the author sees what they own.
git diff --name-only --diff-filter=d <base>...HEAD -- '*.java' # or '*.rs'
Use the PR's merge base as <base>, not HEAD~1: a branch of several commits is one unit of
review. --diff-filter=d drops deleted files, which no tool can measure.
Subsystem mode
Ask the user what the subsystem is if it is not obvious. Do not guess, and do not default to the diff.
In a git repo, the reliable way to find the files a feature owns:
git log --format='%H' --grep='<feature>' -i | while read -r c; do
git show --diff-filter=A --name-only --format='' "$c" -- 'src/**/*.java'
done | sort -u
Beware false positives: an unrelated old commit whose subject contains the same word. Read the commit subjects and drop the ones that do not belong.
Add the files the branch modifies. Then say plainly which files the feature owns and which are pre-existing, because that changes what is safe to touch.
3. Baseline, before any edit
Record all four. Without them you cannot prove the work helped.
- The complexity tool: total points, function count at or over threshold, and the per-file
breakdown. PMD reports all three directly; for Rust, sum
metrics.cognitive.sumyourself. - Duplication: the CPD blocks. Rust has no CPD, so record "not measured" rather than "none".
- Tests: the subsystem's tests, run on a clean build, and the passing count.
- Any performance guard the project already has, for example an allocation test that prints measured bytes. Record the numbers it prints, not just that it passed.
Read the test verdict from the runner's structured output, never from its exit code. For a
JUnit result XML, treat tests="0" as a failure: it means the class never started. For
cargo nextest, read the summary line, and treat a zero-test run the same way.
4. Report before you edit
Group the findings. For each, give the location, the measured cost, and the concrete change. Say which findings are in code the feature owns and which are pre-existing.
Do not rank findings by urgency and do not recommend an order of work. State the facts and let the user choose.
Stop here unless the user passed --refactor. Reporting is the default in both modes.
Sections 5 through 8 edit code; run them only on --refactor. Never start extracting because a
score looks bad, and never treat a bad score as the user asking you to fix it.
5. The constraints that outrank tidiness
Read the subsystem's own documentation first. A hot path usually carries promises that a naive extraction breaks.
- Allocation-free means allocation-free. If a class documents that it allocates nothing per row or per cell, an extraction may not return a new object. Use a reusable holder field.
- No extra copying. A buffer swap must stay a reference swap. Never turn an alias into a copy to make a signature nicer.
- Pure move only. If an extraction changes behaviour, it is not this skill's work. Stop and raise it.
- Coverage must not shrink. A deleted or skipped test is a finding, not a simplification.
Extraction changes JIT inlining in both directions. Never claim smaller is faster. Measure.
6. Work order
Deepest nesting first. Extract the innermost region before the region containing it, or the outer extraction simply inherits the score.
Re-run the complexity tool after each extraction, not once at the end. Then you can say which extraction bought what, and you notice immediately when one buys nothing.
7. Commit discipline
One commit per kind of change. Duplication removal and complexity extraction are separate commits; their diffs are unreadable when mixed.
Never amend unless the user says to. Never push.
If the repo uses a rebased branch stack, a new commit on a lower branch invalidates every branch above it. Say so, and rebase when the user asks.
8. Verify, then report
Clean build. Run the subsystem's tests. Compare against the Section 3 baseline:
- test count must not drop
- performance guard numbers must not regress
- the complexity total must fall, and no function may rise
Report the before and after side by side. If a number moved the wrong way, say so plainly rather than reporting the ones that improved.

# Complexity reduction, measured
Reduce cognitive complexity and duplication in a **subsystem** or in a **diff**. Every claim is a
number from a tool. Every edit is a pure move: behaviour identical, only the shape changes.
Cognitive complexity **at or above 15** for one function marks a potential problem, in every
language below. It is a threshold to report, not a rule to enforce.
## 1. Tools
Pick the tool by language. Never report a number you did not measure.
### Java: `pmd`
`pmd` (Homebrew: `brew install pmd`). Two of its commands matter.
```bash
pmd check -R <skill dir>/pmd-complexity.xml --file-list <list> -f csv -r <out>.csv --no-progress
pmd cpd --minimum-tokens 45 --language java --file-list <list> --format csv
```
`pmd-complexity.xml` beside this file enables CognitiveComplexity (report level 15),
CyclomaticComplexity and NPathComplexity, and nothing else.
### Rust: `rust-code-analysis-cli`
Install it with cargo. **`--locked` is required**: without it, v0.0.25 fails to compile, because
the dependency graph resolves two different `tree-sitter` versions (0.20 expected, 0.27 found).
```bash
cargo install --locked rust-code-analysis-cli
```
Measure, then pull out every function at or above the threshold:
```bash
rust-code-analysis-cli -m -p <path> -O json --pr > <out>.json
```
Scores live in a **recursive** `spaces[]` tree, at `metrics.cognitive.sum`. A flat filter misses
nested functions and closures, so recurse:
```bash
jq -r '
def scores($file):
(if .kind == "function" then
"\($file):\(.start_line)\t\(.name)\t\(.metrics.cognitive.sum)"
else empty end),
(.spaces[]? | scores($file));
. as $r | $r | scores($r.name)' <out>.json \
| awk -F'\t' '$3 >= 15'
```
`-p` takes a file or a directory. For a list of files, **repeat the flag** — `-p a.rs -p b.rs`.
A space-separated list after one `-p` fails, which is exactly the case diff mode hands you. Pass
`-I '*.rs'` to include and `-X` to exclude by glob.
There is no `cpd` equivalent here, so duplication in Rust is a read, not a measurement. Say so
rather than implying a tool checked it.
### Reading the metric
Cognitive Complexity is the SonarSource metric. It charges for nesting depth, so a triply-nested
condition costs far more than three flat ones. That is why extraction of a deeply nested region
buys more than extraction of a long flat one, and it is why you always attack the deepest nesting
first.
`cpd` finds only near-identical token runs. It cannot see a repeated *decision* whose branches
differ. Read for that yourself; it is usually the more valuable finding.
## 2. Pick the mode, then define the file set
Two modes. Ask the user which one if the request does not say.
| Mode | File set | Ends at |
|---|---|---|
| **Subsystem** (default) | The files a feature owns | Section 4, unless `--refactor` |
| **Diff** | The files a diff or PR changes | Section 4, unless `--refactor` |
The mode picks the file set. `--refactor` decides whether anything gets edited, and it is the
only thing that does.
### Diff mode
Score **whole changed files**, not only the functions the diff touched. A small edit can push a
neighbouring function past the threshold, and touched-only scoring hides that. Mark which
findings the diff introduced and which were already there, so the author sees what they own.
```bash
git diff --name-only --diff-filter=d <base>...HEAD -- '*.java' # or '*.rs'
```
Use the PR's merge base as `<base>`, not `HEAD~1`: a branch of several commits is one unit of
review. `--diff-filter=d` drops deleted files, which no tool can measure.
### Subsystem mode
Ask the user what the subsystem is if it is not obvious. Do not guess, and do not default to the
diff.
In a git repo, the reliable way to find the files a feature owns:
```bash
git log --format='%H' --grep='<feature>' -i | while read -r c; do
git show --diff-filter=A --name-only --format='' "$c" -- 'src/**/*.java'
done | sort -u
```
Beware false positives: an unrelated old commit whose subject contains the same word. Read the
commit subjects and drop the ones that do not belong.
Add the files the branch modifies. Then say plainly which files the feature **owns** and which are
pre-existing, because that changes what is safe to touch.
## 3. Baseline, before any edit
Record all four. Without them you cannot prove the work helped.
1. The complexity tool: total points, function count at or over threshold, and the per-file
breakdown. PMD reports all three directly; for Rust, sum `metrics.cognitive.sum` yourself.
2. Duplication: the CPD blocks. Rust has no CPD, so record "not measured" rather than "none".

JUnit result XML, treat `tests="0"` as a failure: it means the class never started. For
`cargo nextest`, read the summary line, and treat a zero-test run the same way.

which findings are in code the feature owns and which are pre-existing.
Do not rank findings by urgency and do not recommend an order of work. State the facts and let the
user choose.
**Stop here unless the user passed `--refactor`.** Reporting is the default in both modes.
Sections 5 through 8 edit code; run them only on `--refactor`. Never start extracting because a
