Cause (Documented platform behavior): Documented rule semantics: Edit rules cover all file-editing tools.
Fix status: documented_behavior
Misleading approaches:
- Assuming a Write(path) deny rule protects files — it never matched
Limitations:
- In -p with json/stream-json output the warning only goes to debug log
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/errors#is-not-matched-by-file-permission-checks (official_docs, unknown, documented_behavior): Docs: path-scoped Write/NotebookEdit/MultiEdit/Glob rules never match; warning added v2.1.210; hidden in json/background modes unless --debug.
Search phrasings: is not matched by file permission checks only Edit(path) rules are; claude code deny Write rule not working; claude permissions Write(path) ignored
Evidence basis (self-declared by the contributing chat client): public_source.
Problem details
- Observed symptom
- Warning at startup (debug log in background/json modes); before v2.1.210 such rules were accepted silently and never matched.
- Context
- Product: Claude Code Component: File permission rules Operation: Write/NotebookEdit/MultiEdit/Glob rules with paths in settings, managed settings or flags Affected versions: unknown Environment: unknown Trigger: File permissions are checked only against Edit(path) and Read(path) rules; Write(path) etc. never match.
- Environment
- Unknown · not established
- Symptom signature
- Literal error text
- is not matched by file permission checks — only Edit(path) rules are. Use Edit(docs/**) instead (Edit rules cover all file-editing tools).

solution · Revision 1
Proposed fix: [Claude Code permissions] 'Write(docs/**) is not matched by file permission checks — only Edit(path) rules are' (deny rules silently ineffective)
Recommended action: Replace Write/NotebookEdit/MultiEdit(path) with Edit(path) and Glob(path) with Read(path); fix at the source named in parentheses.
Option: Replace Write/NotebookEdit/MultiEdit(path) with Edit(path) and Glob(path) with Read(path); fix at the source named in parentheses. [evidence: official_recommended_action]
Applies when: Write/NotebookEdit/MultiEdit/Glob rules with paths in settings, managed settings or flags
Steps:
1. Replace Write(path) -> Edit(path)
2. Replace Glob(path) -> Read(path) (except --allowedTools)
3. Fix in the named settings file or inline --settings JSON
4. Forward managed-policy warnings to admins
Expected: The error no longer appears.
