Also https://www.contracts.md/changelog.json, https://www.contracts.md/changelog.atom and the whats_new tool over the API and MCP. Re-fetch the skill at https://www.contracts.md/contracts.md when the version changes; every API response carries X-MD-Version and X-MD-Updated.

## Changes

### 2026-10-23, version 1.1: Starter files, obligation_calendar, scope_check and parse_contracts

New. Five starter files at /starters, also served by the contract_starter tool: agent subscription, statement of work, API usage terms, data handling and retainer. Each passes check_contract at strict with no errors. obligation_calendar lists every dated obligation across one or more files (deliverables, notice deadlines, renewals, expiries, and payment due dates from invoice dates plus net days) and returns the same list as iCalendar text to save as a .ics file. scope_check tests one planned action against an agreement before the agent acts and answers within, needs_approval or outside, citing the line of each rule. parse_contracts returns a file as canonical JSON with two hashes. The format gains in_scope, out_of_scope and needs_approval tags, the approval_over limit, and count limits such as 1500 requests per month. Files written for 1.0 still read, and a limit like 30 days is no longer taken for money.

### 2026-10-22, version 1.0: CONTRACTS.md: the format and 6 tools

New. The CONTRACTS.md format, version 1: one section per agreement with parties, scope, deliverables, price, payment terms, service levels, credits, limits, term, notice, renewal, dispute path and status. Six read-only tools over HTTP and MCP: check_contract lints a file with line numbers, key_dates works out the last day to give notice, the renewal date, expiry and days left, term_cost adds up a term with proration, a yearly escalator and a one-time fee, compare_contracts tables the differences between two files, sla_credit turns stated targets, measured numbers and the stated credit ladder into a credit, and contract_template writes a file to save. Plus the skill, settings, this changelog and the whats_new tool.

## What's next

Being built (no dates; check back):

- A merge tool: Two copies in, a merged copy out, matched by agreement id. The newer copy wins, a status never moves backwards, and every change is listed with its line.
- Invoice and deliverable checks: Match an invoice (amount, period, due date) and a list of delivered items against an agreement's price, payment terms and deliverables, and flag what does not fit.

Ideas being weighed (not promised):

- Done marks for dated items: A way to record in the file that a deliverable was delivered, an invoice was paid or notice was given, so obligation_calendar and scope_check can leave finished items out.
- Amendment records: A sub-section per agreement that records what changed and when, so compare_contracts can show an agreement's history, not only two files.
