* refactor: replace manual urlencoded() with reqwest .query() builder
Remove duplicate hand-rolled urlencoded() functions from workflows.rs
and calendar.rs. All query parameters are now passed via reqwest's
.query() API, which handles percent-encoding correctly and completely.
* fix: percent-encode path parameters to prevent path traversal
Use percent_encoding::utf8_percent_encode for calendar_id, cal.id,
message_id, and file_id before interpolating into URL path segments.
Addresses code review feedback on security regression.
* fix: add shared URL safety helpers for path params
Add encode_path_segment() for single-segment IDs and
validate_resource_name() for multi-segment resource names.
encode_path_segment: percent-encodes all non-alphanumeric chars,
used for calendar IDs, file IDs, and message IDs.
validate_resource_name: rejects path traversal (..) and control
chars while preserving intentional / structure, used for Chat
space names, task list IDs, and subscription names. Returns clear
error messages for LLM callers.
* test: add AI edge case tests for URL safety helpers
Cover query/fragment injection, double-encoding, unicode, spaces,
path traversal via encoding, control chars (CR/tab), and clear
error message assertions for LLM callers.
* fix: warn on stderr when API calls fail silently
- Daily briefing calendar events fetch
- Daily briefing tasks fetch
- Daily summary calendar events fetch
- Daily summary unread email count fetch
Addresses PR review feedback about confusing silent failures,
especially for LLM callers that cannot see visual cues.
* fix: harden input validation for AI/LLM callers
- Add src/validate.rs with validate_safe_output_dir, validate_msg_format,
and validate_safe_dir_path helpers
- Validate --output-dir against path traversal in gmail +watch and
events +subscribe
- Validate --msg-format against allowlist in gmail +watch
- Validate --dir against path traversal in script +push
- Add clap value_parser constraint for --msg-format
- Document input validation patterns in AGENTS.md
Closes#23
* chore: add changesets for PR #21 commits
* test: add comprehensive test coverage for input validation handlers
* docs: document input validation and URL safety patterns in AGENTS.md and CONTRIBUTING.md
* fix: address PR review comments — reject ?/# in resource names, validate subscription arg, remove redundant validate_msg_format
* fix: store validated PathBuf, remove dead code, delete duplicate SubscribeConfig
Addresses review comments:
- Store validated PathBuf from validate_safe_output_dir instead of
discarding it (output_dir is now Option<PathBuf>)
- Remove duplicate SubscribeConfig from events/mod.rs
- Delete unused validate_msg_format (clap value_parser handles this)
- Remove all #[allow(dead_code)] annotations
* fix: per-segment traversal check in validate_resource_name, fix docs
* fix: harden security validation and deduplicate logic
