ECC 2.2.2

ECC 2.2.2 adds pi/core, a curated Pi-native skills+prompts-only profile built for downstream packagers that mirror GitHub Releases, plus a set of packaging, memory, hooks, and Windows compatibility fixes.

Pi core profile

pi/core/ is a self-contained package (ecc-pi-core) that downstream mirrors of the release tarball can copy directly: no build step, no extensions, no hooks, no runtime downloads, and no network or SaaS dependencies.

• 123 curated skills (language and framework patterns, testing/TDD, code review, non-offensive security review, planning, refactoring, docs, and git/PR workflows) and 24 prompt commands that are pure prompt workflows.
• Generated deterministically from the explicit include/exclude lists in manifests/pi-core.json by scripts/build-pi-core.js and committed, so the release tarball contains it verbatim. pi/core/CURATION.md lists every excluded skill and command with its reason; the council skill ships as ecc-council inside pi/core to avoid catalog name clashes.
• The build fails on safety violations: non-allowlisted URL hosts, pipe-to-shell or fetch-and-run download forms, secrets or tokens, absolute per-user home paths, symlinks, invalid SKILL.md frontmatter, and duplicate skill names.
• CI rebuilds pi/core on every PR and verifies it is up to date, then installs the Pi coding agent CLI and proves the profile loads fully offline (PI_OFFLINE=1), asserting that every curated command actually registers.
• The release workflow additionally verifies that VERSION matches the tag and that pi/core is current before publishing.

Downstream consumption: poll /releases, download archive/refs/tags/vX.Y.Z.tar.gz, pin its sha256, copy pi/core/, and load it offline with pi --offline --skill pi/core/skills --prompt-template pi/core/commands.

Packaging

• The compiled OpenCode payload is explicitly included in the npm package, and packing is verified from a clean state with lifecycle scripts enabled.

Memory and MCP

• Incomplete memory reads are distinguished from missing records, and directory traversal failures are classified.
• The reserved _meta parameter is accepted on memory MCP ping requests.

Hooks and Windows compatibility

• hooks.json stays within Claude Code's schema; stable hook metadata moved into a validated sidecar.
• The no-verify guard handles stuck optional values and long-option prefixes.
• Windows linter paths and ESLint 9 are supported, and settings updates tolerate missing Windows device IDs while retaining full-precision inode checks.

Workflow guidance, catalog, and dependency security

• Epic sync filters issues by label; dependency bumps no longer document auto-merge; naming and Boolean guidance is language-neutral; the prp-pr command alias is distinguished; Rails skill discovery, invoice tax calculation order, and framework documentation were corrected; Serply and Squish catalog entries were removed.
• lru updated to 0.18.2 (RUSTSEC-2026-0253) and js-yaml to 4.3.2 (GHSA-2883-xcg3-v3hh).
