- Split CODING_GUIDELINES.md into 19 indexed standards files under .claude/standards/ - 9 from CODING_GUIDELINES (conventions, powershell, security, api, git, gururmm) - 10 from session log tribal knowledge (syncro, ssh, gitea, python, client, gururmm) - Add .claude/standards/index.yml for cheap relevance-based lookup - Add /inject-standards command: load targeted standards per task instead of full guidelines - Add /shape-spec command: pre-implementation spec for GuruRMM features (plan.md, shape.md, references.md, standards.md) with mandatory out-of-scope gate - Add docs/tech-stack.md and docs/mission.md for ClaudeTools API - Add projects/msp-tools/guru-rmm/docs/tech-stack.md and mission.md for GuruRMM - Update CLAUDE.md commands table with /inject-standards and /shape-spec Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

| tmp-path-windows | /tmp resolves to different directories in Git Bash vs Write tool on Windows; use .claude/tmp/ instead | all |
/tmp Path Mismatch on Windows
The problem
On Windows, /tmp resolves to two different real directories depending on which tool accesses it:
| Tool | /tmp resolves to |
|---|---|
| Git Bash / curl | %LOCALAPPDATA%\Temp\ (e.g., C:\Users\Howard\AppData\Local\Temp\) |
| Claude Code Write tool | C:\tmp\ |
These are different directories. If you write a file with the Write tool to /tmp/payload.json and then read it back with curl in a Bash command, curl reads a stale file from a previous session — or a completely different file.
Incident that established this rule
2026-05-01: The Write tool created /tmp/comment_payload.json in C:\tmp\. curl read /tmp/comment_payload.json from %LOCALAPPDATA%\Temp\ — a stale payload from the previous day's Cascades session. The wrong comment (containing Karen Rossini / ALDOCS content) was posted to a Sombra ticket. The comment could not be deleted via the Syncro API.
The fix: use .claude/tmp/ or heredocs
Option 1 — Heredoc (preferred for JSON payloads):
curl -s -X POST "${URL}" -H "Content-Type: application/json" --data-binary @- <<'JSON'
{"key": "value", "other": "data"}
JSON
No file involved — no path ambiguity. Use <<'JSON' for static content and <<JSON when you need shell variable interpolation.
Option 2 — .claude/tmp/ directory:
Both the Write tool and Git Bash agree on the absolute Windows path when you use the repo-relative temp directory:
D:/claudetools/.claude/tmp/
Write files there using the Write tool, then read them in Bash with D:/claudetools/.claude/tmp/filename. Forward slashes work in Git Bash.
# After writing with Write tool to D:/claudetools/.claude/tmp/payload.json
curl -s -X POST "${URL}" -H "Content-Type: application/json" \
-d @D:/claudetools/.claude/tmp/payload.json
Option 3 — Python urllib (no file at all):
py -c "
import urllib.request, json
data = json.dumps({'key': 'value'}).encode()
req = urllib.request.Request('$URL', data=data, headers={'Content-Type': 'application/json'})
print(urllib.request.urlopen(req).status)
"
Applies to
Any workflow where the Write tool creates a file that is subsequently read by a Bash command on Windows. This includes:
- Syncro API payloads
- PowerShell script files (use .claude/tmp/ or the Write tool with an absolute path)
- Any temp file exchange between Write tool and Bash tool
