Distillery v0.3.0 — Team Skills, Session Hooks & Corrections Chain

[norrietaylor]

Distillery v0.3.0 is out — the team release. Four new team skills, session hooks, a corrections chain, and new data model fields for entry lifecycle management.

Team Skills

Distillery grows from a solo knowledge base to a team-aware system with four new skills:

• /digest — team activity summaries across your shared knowledge base. See what your team has been capturing, reviewing, and correcting.
• /gh-sync — syncs GitHub issues and PRs into Distillery as knowledge entries. Track decisions, context, and outcomes alongside your other knowledge.
• /investigate — deep context builder that assembles a structured research brief from multiple knowledge entries, feed items, and GitHub activity. Use it before a meeting or when onboarding to a new area.
• /briefing — rewritten as a solo-first knowledge dashboard that also supports team mode. The default surfaces your personal activity, review queue, and recent entries. Pass --team for the full team view.

All four skills are transport-agnostic — they work over both stdio (local) and HTTP (hosted team) transports.

Session Hooks

Distillery now hooks into Claude Code's lifecycle events:

• UserPromptSubmit — nudges memory capture by counting prompts in your session and surfacing a reminder when you've been working for a while without distilling
• SessionStart — fires a briefing hook on session start so your knowledge dashboard greets you automatically

The /setup skill configures these hooks with scope-aware placement — plugin-level vs. project-level depending on your setup.

Corrections Chain

New distillery_correct tool lets you amend existing entries without losing provenance:

• Creates correction entries linked via entry_relations table
• Budget and size gates prevent runaway corrections
• Reserved tag-prefix guard (correction/) keeps corrections namespaced
• Transactions wrap the full write set atomically

Data Model Extensions

• session_id — first-class field on entries, exposed on MCP tool signatures, enabling session-scoped queries
• expires_at — time-limited entries with UTC normalization and date-only rejection
• verification — orthogonal quality tracking field for entry confidence scoring
• EntrySource expanded with inference, documentation, and external provenance values

Eval Improvements

• 11 new promptfoo scenarios covering features since v0.2.1
• Graders updated to tolerate Agent/Skill delegation patterns

Maintenance

• DuckDB lifespan shutdown now checkpoints WAL properly
• Feed SyncResult refactored to dataclass with retry + rate-limit handling
• Plugin version pinned to release tags with server version compatibility
• RELEASING.md documents the full release process
