- Accept hard upper limit (maxLen) instead of pre-subtracted value
- Caller now passes actual platform limit (e.g., 2000 for Discord)
- Internal buffer of 500 chars is handled within message.go
- Preferred split at maxLen - 500, may extend to maxLen for code blocks
- Never exceeds maxLen, no more mental math for callers
- Move FindLast, findLast, and SplitMessage from discord.go to pkg/utils/message.go
- Update discord.go to use utils.SplitMessage()
- Makes splitting logic reusable across other channels
Extract common file download and audio detection logic to utils package,
implement consistent temp file cleanup with defer, add allowlist checks
before downloading attachments, and improve context management across
Discord, Slack, and Telegram channels. Replace logging with structured
logger and prevent context leaks in transcription and thinking animations.
Code review fixes:
- Use map for O(n) job lookup in cron service (was O(n²))
- Set DeleteAfterRun=true for one-time cron tasks
- Restore context compression/summarization to prevent context overflow
- Add pkg/utils/string.go with Unicode-aware Truncate function
- Simplify setupCronTool to return only CronService
- Change Chinese comments to English in context.go
Refactoring:
- Replace toolsSummary callback with SetToolsRegistry setter pattern
- This makes dependency injection clearer and easier to test
