Skillscript — What's New

Pragmatic, task-oriented notes on each release: what changed, why you'd care, and how to use it. This is the friendly companion to the CHANGELOG — the CHANGELOG is the terse authoritative record (every change + its upgrade impact); these pages are the "here's the feature, here's how you'd actually use it" walkthrough.

If you're deciding whether a release matters to you, start here. If you need the exact list of what changed, read the CHANGELOG.

Release notes

Newest first. Each page covers the problem a release solves, the few things you can now do, a copy-paste example, and the gotchas.

• 0.37.0 — Bounding external work: the right lever — per-leg timeout= + (fallback:) for a partial-tolerant gather, vs. the whole-run # Deadline: cap.
• 0.36.0 — Autonomous-fire failure supervision — a cron/event run fails; the runtime pushes it to a handler skill instead of leaving it in a trace nobody reads.
• 0.35.0 — Deadlines & cancellation — bound a whole run in wall-clock time; real cancellation, not race-and-abandon.
• 0.34.0 — REST-backed connectors + secret hardening — a plain REST API is a first-class connector (no MCP server needed); shell ops no longer leak secrets into child processes.

Feature guides

Deeper how-tos for individual capabilities, independent of the release they shipped in.

• Tagging skills (# Tags:) — organize and find skills; group a big skill menu into families.

Where else to look

• Language reference — the canonical spec (syntax, ops, semantics): docs/language-reference.md
• Adopter playbook — wiring substrates, security boundaries, running as a service: docs/adopter-playbook.md
• help({topic}) — the language surface, reachable from your agent over MCP (ops, frontmatter, connectors, lint-codes, error-handling).
