From f0d4a5e7857e3e0215023e90b5a095e351c59c55 Mon Sep 17 00:00:00 2001 From: ApiliumDevTeam Date: Tue, 14 Jul 2026 10:56:16 +0200 Subject: [PATCH] feat(skills): official akashi skill, connect the user's second brain Query-first grounded retrieval against the user's Akashi vault over the mcp-client extension (HTTP + per-runtime bearer token): mandatory source:lines citations with signed provenance, groundedness verdicts surfaced, consent-based write-back following vault conventions, and typed helpers for the ground response shape with tests. Akashi never executes; tool results are treated as data. Published to the Hub as slug akashi; joins the 8 official skills at platinum quality (README, CHANGELOG, LICENSE, types, tests). --- skills/official/akashi/CHANGELOG.md | 15 ++++ skills/official/akashi/LICENSE | 21 ++++++ skills/official/akashi/README.md | 64 +++++++++++++++++ skills/official/akashi/SKILL.md | 90 ++++++++++++++++++++++++ skills/official/akashi/citations.test.ts | 50 +++++++++++++ skills/official/akashi/citations.ts | 21 ++++++ skills/official/akashi/package.json | 17 +++++ skills/official/akashi/tsconfig.json | 11 +++ skills/official/akashi/types.ts | 32 +++++++++ 9 files changed, 321 insertions(+) create mode 100644 skills/official/akashi/CHANGELOG.md create mode 100644 skills/official/akashi/LICENSE create mode 100644 skills/official/akashi/README.md create mode 100644 skills/official/akashi/SKILL.md create mode 100644 skills/official/akashi/citations.test.ts create mode 100644 skills/official/akashi/citations.ts create mode 100644 skills/official/akashi/package.json create mode 100644 skills/official/akashi/tsconfig.json create mode 100644 skills/official/akashi/types.ts diff --git a/skills/official/akashi/CHANGELOG.md b/skills/official/akashi/CHANGELOG.md new file mode 100644 index 00000000..d8584293 --- /dev/null +++ b/skills/official/akashi/CHANGELOG.md @@ -0,0 +1,15 @@ +# Changelog + +## 1.0.0 (2026-07-14) + +First release of the official Akashi skill for Mayros. + +- Connection bootstrap via the `mcp-client` extension (HTTP transport, + per-runtime bearer token). +- Query-first grounded retrieval protocol over `aingle_ground`, + `aingle_vault_map`, `aingle_note_context`, and `aingle_sources`. +- Honesty rules: mandatory `source:lines` citations, groundedness verdicts + surfaced, stale-index warnings, no invented vault content. +- Consent-based write-back following vault conventions. +- Typed helpers for the ground response shape and canonical citations + (`types.ts`, `citations.ts`) with tests. diff --git a/skills/official/akashi/LICENSE b/skills/official/akashi/LICENSE new file mode 100644 index 00000000..a574083e --- /dev/null +++ b/skills/official/akashi/LICENSE @@ -0,0 +1,21 @@ +MIT License + +Copyright (c) 2026 Apilium Technologies OÜ + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
