Why This Matters

When AI coding agents search for functions to complete a task, they rely on function
names to understand what code does. Clear, descriptive names increase the likelihood
that an agent will find the right function instead of reimplementing existing logic.
Functions in the same package also call each other, so reviewing them together gives
better context for rename decisions.

Rename Suggestions

pkg/fileutil/executable.go

No rename suggestions in this file.

All functions in this file (for reference):

• ResolveExecutablePath() — ✅ Clear, no change needed

pkg/fileutil/fileutil.go

Current Name	Suggested Name	Reason
resolveWithAncestorSymlinks()	resolvePathWithExistingAncestorSymlinks()	The current name hints at symlink handling but does not make the key behavior discoverable: it resolves a path by walking up to the longest existing ancestor when the final path may not exist yet. The suggested name surfaces both path resolution intent and the existing-ancestor fallback that callers care about when searching for safe path-boundary logic.
copyFileContents()	copyToFileAndSync()	The current name sounds like a generic reader-to-writer copy helper, but the function also syncs the destination and removes partial output on failure. The suggested name better exposes that this helper writes into a file-like destination and performs a durability step agents would otherwise miss.

🤖 Agentic Implementation Plan

Agentic Implementation Plan

This issue is designed to be assigned to a coding agent. The agent should implement
all rename suggestions below in a single pull request.

Prerequisites

• Read each rename suggestion and verify it is accurate by reviewing the function body
• Check for any Go interface constraints that prevent renaming (e.g., must match interface method name)

Implementation Steps

For each rename suggestion, follow this sequence:

1. Rename the function in pkg/fileutil/fileutil.go

// Old
func resolveWithAncestorSymlinks(p string) (string, error) {

// New
func resolvePathWithExistingAncestorSymlinks(p string) (string, error) {

// Old
func copyFileContents(in io.Reader, out syncWriteCloser, dst string) (err error) {

// New
func copyToFileAndSync(in io.Reader, out syncWriteCloser, dst string) (err error) {

2. Update all call sites

Use grep to find every caller and update the reference:

grep -rn "resolveWithAncestorSymlinks\|copyFileContents" pkg/ --include="*.go"

Also check test files:

grep -rn "resolveWithAncestorSymlinks\|copyFileContents" pkg/ --include="*_test.go"

Known references from this analysis:

• ValidatePathWithinBase() calls resolveWithAncestorSymlinks() in pkg/fileutil/fileutil.go
• CopyFile() calls copyFileContents() in pkg/fileutil/fileutil.go
• TestCopyFileContents() references copyFileContents() in pkg/fileutil/fileutil_test.go

3. Verify compilation after each rename

make build

4. Run tests after all renames are complete

make test-unit
make lint

Commit Convention

Each rename should be a focused commit:

refactor: rename <oldName> to <newName> for clarity

Validation Checklist

• All renames implemented
• All call sites updated (Go files and test files)
• make build passes with no errors
• make test-unit passes
• make lint passes
• PR description explains the agent-discoverability rationale

Notes for the Agent

• This is a pure rename refactor — behavior must not change, only names
• If a rename causes unexpected complexity (e.g., name conflicts, interface constraints),
  skip it and leave a comment in the PR explaining why
• Follow existing naming conventions documented in AGENTS.md
• Unexported functions used only as closures or immediately-invoked can be skipped
