Windows: projectTranscriptDir mis-encodes cwd (backslash/colon/space)

[Reapper-Stack]

Bug

On Windows, /cco-overhead (and any command using projectTranscriptDir) reports "No session transcripts found" even when transcripts exist. It looks in a malformed path, e.g.:

Looked in: C:\Users\User\.claude\projects\C:\Program Files\Git

The real transcript folder is ...\projects\C--Program-Files-Git.

Root cause

src/overhead.js:

export function projectTranscriptDir(cwd) {
  return join(homedir(), ".claude", "projects", cwd.replace(/[/.]/g, "-"));
}

The regex only replaces / and .. On Windows the cwd contains \, :, and spaces (e.g. C:\Program Files\Git), which Claude Code's own transcript-folder naming also converts to - (giving C--Program-Files-Git). Since those chars are not replaced, the path stays malformed and no transcripts are found. This also silently breaks the MEMORY.md / CLAUDE.md itemization (same helper), so everything is lumped into the "system prompt/tools/MCP" line.

Fix

Broaden the character class to match Claude Code's folder encoding:

return join(homedir(), ".claude", "projects", cwd.replace(/[/.:\\ ]/g, "-"));

C:\Program Files\Git becomes C--Program-Files-Git. (The helper appears duplicated across other command scripts - worth a shared util fix.)

Workaround

Pass a transcript path directly, which bypasses the folder scan:

node src/overhead.js <path-to-a-session>.jsonl

Env

Windows 11, Claude Code 2.1.198, cco 4.3.0, Node 24.
