Update Changelog

Update Changelog

After making significant project changes or decisions, record them in the "Recent Updates & Decisions" section at the bottom of AGENTS.md.

---

When to Update

Add an entry whenever you:

• Make a technology or architecture decision
• Establish or change a coding convention
• Add, remove, or rename features or commands
• Perform significant refactoring
• Bump the project version
• Change build, test, or deployment procedures
• Make any decision that future contributors should know about

---

Entry Format

Each entry starts with a heading containing the date, time, and an optional short label:

### YYYY-MM-DD HH:MM (label)

- Description of change or decision
- Reasoning if non-obvious
- Version bump if applicable

Rules:

• Use ISO date format: YYYY-MM-DD
• Always include the time in 24-hour format: HH:MM
• Add a parenthetical label when the change needs a short identifier (e.g. version number, feature name)
• Use bullet points for individual items within an entry
• Keep each bullet concise: what changed and why
• Mention version bumps inline: Version bump: X.Y.Z to X.Y.Z (TYPE - reason)
• Newest entries go first (reverse chronological order)

---

Where to Write

The section must be at the end of AGENTS.md. Look for:

## Recent Updates & Decisions

If the section does not exist, create it by appending the following to the bottom of AGENTS.md:

---

## Recent Updates & Decisions

Then add the new entry below the heading.

Also update the Last updated timestamp near the top of AGENTS.md to today's date.
