Hone:intent Clarity Audit

Intent Clarity Audit

What This Skill Does

Audits source code for patterns that make it harder to understand what the code is doing and why. Focuses on five categories of intent obscurity:

1. Unclear names: Single-letter variables outside tiny loops, generic names (data, temp, result, val, info, item) in non-trivial scopes, abbreviated names that sacrifice readability.
2. Nested ternaries: Ternary or conditional expressions nested two or more levels deep.
3. Unnamed boolean parameters: Function calls passing bare true/false literals without a named parameter, comment, or object wrapper to explain the meaning.
4. Overly clever one-liners: Dense expressions that chain multiple operations, bitwise tricks used for non-bitwise purposes, regex used inline without explanation, or reduce/fold with complex accumulators.
5. Restating comments: Comments that describe what the next line does rather than why (e.g., // increment counter before counter++).

Reports findings with file:line, the offending snippet, the category, and a brief explanation of why it harms clarity.

When To Use

• On a weekly schedule to audit recently changed files.
• After a large feature branch merges.
• When reviewing code written by unfamiliar contributors.
• When the user asks to "find unclear code" or "audit code clarity".

Do Not Use

• For method length — use hone:method-brevity-audit instead.
• For duplicated code — use hone:duplication-hunt instead.
• For test naming — use hone:test-naming-audit instead.
• For naming specificity (Manager, Handler, Utils) — use hone:naming-specificity-audit instead.
• To rewrite code. This skill reports findings only.

Inputs To Confirm

1. Scope: Which directories or file patterns to scan (default: files changed in the last 14 days per git log, falling back to entire repo if no git history).
2. Recency window: Number of days to look back for changed files (default: 14).
3. Categories: Which of the five categories to check (default: all).
4. Exclusions: Glob patterns for files or directories to skip.
5. Top-N: Maximum findings to report (default: 25).

Instructions

1. Determine file scope. If git history is available, run git log --since="<N> days ago" --diff-filter=ACMR --name-only to get recently changed files. Deduplicate and filter to source files only. If git is unavailable, scan the full tree (respecting exclusions).

2. Exclude non-source files. Skip vendored directories, build output, generated files, lock files, binary files, and user-specified exclusions.

3. Scan each file for all enabled categories. For each source file:

   a. Unclear names: Identify variable, parameter, and function declarations. Flag single-character names outside for/while loop indices of 5 lines or fewer. Flag generic names (data, temp, result, val, info, item, obj, thing, stuff, foo, bar, x, y outside math) in scopes longer than 3 lines.

   b. Nested ternaries: Find ternary operators (?: in C-family, if/else inline in Python, etc.) where a ternary appears inside another ternary expression.

   c. Unnamed booleans: Find function/method calls with bare boolean literal arguments. Exclude well-known single-boolean APIs (e.g., setVisible(true), Array.sort(reverse=true) with keyword syntax).

   d. Clever one-liners: Flag lines that combine 3+ chained operations, use bitwise operators in non-bitwise contexts, contain inline regex longer than 40 characters without a comment, or use reduce/fold with accumulators longer than one line.

   e. Restating comments: Find comments directly above or inline with code where the comment merely describes the operation (e.g., "add 1 to x" above x += 1). Use simple heuristic: if the comment contains the same verbs/nouns as the code tokens, flag it.

4. Classify severity. For each finding assign a severity:

   • High: Nested ternaries 3+ deep, single-letter names in 20+ line scopes, boolean parameters in public API calls.
   • Medium: Two-level nested ternaries, generic names in 5-20 line scopes, clever one-liners.
   • Low: Restating comments, minor naming issues.

5. Rank and truncate. Sort by severity (high first), then by file path for grouping. Truncate to top-N.

6. Produce the report per Output Requirements.

Output Requirements

Produce a Markdown report:

# Intent Clarity Audit

**Repo**: <repo name>
**Scope**: <N> files changed in last <D> days | **Findings**: <count>

## Findings

### High Severity

| # | Category | File | Line | Snippet | Why |
|---|----------|------|------|---------|-----|
| 1 | Nested ternary | src/parser.ts | 142 | `a ? b ? c : d : e` | 2-level nested ternary obscures control flow |

### Medium Severity

| ... |

### Low Severity

| ... |

## Summary

- **By category**: 5 unclear names, 3 nested ternaries, 2 unnamed booleans, ...
- **Hotspot files**: file1.ts (7 findings), file2.py (4 findings)
- **Trend**: [if prior run data available, compare finding counts]

Every finding must reference a real file path and line number. Snippets must be actual code from the file, truncated to fit a table cell (max 80 characters).

Quality Bar

• Every finding must be verifiable at the stated file:line.
• Snippets must be real code, not fabricated examples.
• Severity assignments must follow the criteria defined in step 4.
• Do not flag idiomatic patterns that are universally understood in the language (e.g., i in a 3-line for loop, _ for unused variables).
• Do not flag code in test fixtures or snapshot files.
• If no findings exist, state that explicitly.
• Keep the "Why" column concise (one sentence) and specific to the finding.
