processkit v0.5.0 — provider-neutral install + 11 MCP servers + all 18 schemas

processkit v0.5.0 lands the consumer-side install layout (per the aibox handover v2) and fills the major content gaps from BACK-002, BACK-003, BACK-004.

Highlights

Provider-neutral install paths

• All mcp-config.json fragments use context/skills/<name>/mcp/server.py
• The lib resolves consumer-installed schemas at context/schemas/ and state machines at context/state-machines/
• _find_lib() walks up to context/skills/_lib/processkit/ in installs
• Runtime cache moved to context/.cache/processkit/index.sqlite (gitignored)
• All references to .claude/skills/ removed from shipped content
• Reference-templates model documented (replaces processkit.manifest)

AGENTS.md as canonical agent entry

• New AGENTS.md at the repo root holds the authoritative instructions (per the agents.md ecosystem convention)
• CLAUDE.md is a thin pointer
• New src/scaffolding/AGENTS.md template for consumer projects

BACK-002 — all 18 primitive schemas

• 14 new: Actor, Role, Scope, Gate, Discussion, Binding, Category, Metric, Schedule, Constraint, Context, Process, StateMachine, Artifact
• 2 new state machines: scope, discussion

BACK-003 — 11 MCP servers (was 6)

• 5 new: actor-profile, role-management, scope-management, gate-management, discussion-management
• Each follows the existing boilerplate, validates against its schema, and is exercised end-to-end in scripts/smoke-test-servers.py

BACK-004 — 4 Process entities under src/processes/

• bug-fix, code-review, feature-development, release
• Promoted from legacy aibox .md files to formal kind: Process entities

BACK-007 — WAL mode in the SQLite index

Release-asset tarball convention (DEC-025 / aibox BACK-106)

• This release is the first to ship a processkit-<version>.tar.gz release asset alongside the source tag
• Reproducible via scripts/build-release-tarball.sh
• Top-level entry inside the tarball is processkit-v0.5.0/ so consumers can untar without --strip-components
• Sibling .sha256 file for verification

Other

• 80-column line-width policy with smart exemptions (encoded in .editorconfig, documented in AGENTS.md and CONTRIBUTING.md)
• Aibox issues filed: projectious-work/aibox#33 (AGENTS.md scaffolding), projectious-work/aibox#34 (sync perimeter docs)

Verifying the release asset

sha256sum -c processkit-v0.5.0.tar.gz.sha256

Expected:

processkit-v0.5.0.tar.gz: OK
