feat(terraphim-skills-intro): add community skills

[AlexMikhalev]

What / 改动内容

Adds Terraphim Skills Introduction v0.2.2 to the official ZCode marketplace. The plugin gives agents three local-first Community skills for bounded code/document search, explicit operational learning capture, and role-scoped memory retrieval with provenance.

User-visible behavior

• Installs exactly terraphim-grep, terraphim-agent-learn, and terraphim-agent-memory.
• Documents Homebrew and signed-release dependency installation without automatic software installation.
• Defaults search to local/read-only operation; learning and memory writes require an explicit user request.
• Links neutrally to the Terraphim catalogue without checkout, transaction initiation, or bundled proprietary content.

Validation

• python3 scripts/validate.py: 22 plugins accepted.
• python3 scripts/build_dist.py: passed; Terraphim ZIP SHA-256 c96cd194e7bb1d1c56c0453b357fb1e33f295cd4b017f773e2f4d197d6ba0f92.
• ZIP integrity and 14-member inventory passed, including LICENSE and NOTICE.
• Installed Terraphim Clients v1.21.14 confirms every documented command and flag.
• Source skill files, signatures, and hashes match the immutable, SSH-signed public v0.2.2 release.
• Independent structured review: 5/5, no remaining P0/P1/P2 findings.
• Real ZCode GUI installation is transparently outstanding because the validation Mac is locked; the official validator, deterministic build, package inventory, command compatibility, and embedded ZCode CLI checks have completed.

Dependencies, permissions, and side effects

• Runtime binaries: terraphim-grep and terraphim-agent, installed separately by the user.
• Search reads only selected local paths.
• Learning/memory may write only to the user's configured local Terraphim store after an explicit request.
• Optional model synthesis is disabled by default; if requested, it may use the user's configured provider and incur provider charges.
• No bundled credentials, executables, hooks, background tasks, private endpoints, or telemetry.

Licence and provenance

Apache-2.0. Canonical LICENSE and NOTICE from the signed v0.2.2 source are bundled in the installable artifact. Source: https://github.com/terraphim/terraphim-cursor-plugin/tree/v0.2.2

Self-check / 自查清单

• Plugin name is unique kebab-case; directory is plugins/terraphim-skills-intro/
• version is identical in plugin.json and marketplace.json
• README.md and README_CN.md are equivalent
• description_i18n includes en and zh-CN
• No secrets, machine-specific paths, or private dependencies
• Model/API/network dependencies and side effects are documented
• validate.py, build_dist.py, and git diff --check pass

Additional real-host validation completed against the public terraphim/terraphim-cursor-plugin v0.2.2 repository using ZCode 0.15.2 in an isolated storage profile:

• plugins/marketplace/add added the public GitHub repository with no diagnostics.
• plugins/overview discovered terraphim-skills-intro v0.2.2.
• plugins/install installed it enabled at user scope with no diagnostics.
• plugins/validate returned ok: true with no diagnostics.
• plugins/describe returned exactly the three intended skills: terraphim-grep, terraphim-agent-learn, and terraphim-agent-memory.

This supplements the already-passing repository validator, distribution build, archive-integrity check, and independent structured review. GUI UAT remains explicitly separate from this app-server/CLI proof.

Updated the submission to Terraphim Skills Introduction v0.2.3.

• canonical homepage: https://terraphim-skills.md/
• canonical privacy policy: https://terraphim-skills.md/legal/privacy/
• release: https://github.com/terraphim/terraphim-cursor-plugin/releases/tag/v0.2.3
• release workflow: https://github.com/terraphim/terraphim-cursor-plugin/actions/runs/35075813921

The bundled plugin now uses first-party Terraphim links in end-user collateral, includes the re-signed v1.0.2 Community skills, and preserves GitHub only as machine-readable source provenance.

Validation repeated after rebasing onto current upstream main:

• python3 scripts/validate.py — 22 plugins passed
• python3 scripts/build_dist.py — built v0.2.3 package, SHA-256 3b249c96a65b…
• tsm validate — passed for all three signed Community skills
• git diff --check — passed
