From 3444cc5301f04690ed01d546f32b3928066ff046 Mon Sep 17 00:00:00 2001 From: Sergio Marcelino Date: Wed, 13 May 2026 18:10:47 -0300 Subject: [PATCH 1/2] Refactor skill handling in iii-directory - Updated skill retrieval methods: replaced `directory::skills::fetch-skill` with `directory::skills::get` for fetching individual skill bodies. - Enhanced `directory::skills::list` to return enriched skill metadata including title and description. - Adjusted related documentation and comments to reflect the new method names and their usage. - Removed deprecated `fetch-skill` references throughout the codebase and documentation. - Updated tests to align with the new skill handling approach. --- AGENTS-NEW-WORKER.md | 41 +- harness/docs/iii-skill.md | 8 +- harness/web/src/App.tsx | 2 +- harness/web/src/components/Composer.tsx | 17 +- harness/web/src/menuItems.test.ts | 78 +- harness/web/src/menuItems.ts | 58 +- iii-directory/README.md | 52 +- iii-directory/config.yaml | 8 +- .../skills/directory/engine/functions/info.md | 15 +- iii-directory/skills/directory/prompts.md | 130 +++ .../skills/directory/skills/download.md | 10 +- .../skills/directory/skills/fetch-skill.md | 118 --- iii-directory/skills/directory/skills/get.md | 98 +++ iii-directory/skills/directory/skills/list.md | 63 +- iii-directory/skills/index.md | 8 +- iii-directory/src/config.rs | 9 +- iii-directory/src/functions/directory.rs | 4 +- iii-directory/src/functions/mod.rs | 2 +- iii-directory/src/functions/skills.rs | 779 ++++-------------- iii-directory/src/how_to.rs | 10 +- iii-directory/src/lib.rs | 8 +- iii-directory/src/main.rs | 2 +- iii-directory/tests/features/read.feature | 127 ++- iii-directory/tests/steps/read.rs | 145 ++-- shell/src/lib.rs | 4 +- turn-orchestrator/src/agent_call.rs | 21 +- turn-orchestrator/src/states/provisioning.rs | 232 ++++-- turn-orchestrator/src/system_prompt.rs | 39 +- 28 files changed, 959 insertions(+), 1129 deletions(-) create mode 100644 iii-directory/skills/directory/prompts.md delete mode 100644 iii-directory/skills/directory/skills/fetch-skill.md create mode 100644 iii-directory/skills/directory/skills/get.md diff --git a/AGENTS-NEW-WORKER.md b/AGENTS-NEW-WORKER.md index 08e8d633..d7911253 100644 --- a/AGENTS-NEW-WORKER.md +++ b/AGENTS-NEW-WORKER.md @@ -207,8 +207,6 @@ links every worker. - 1+ segments separated by `/`. - Each segment: lowercase ASCII letters, digits, `-`, `_`; max 64 chars per segment. - Total id length ≤ 1024 chars. -- First segment MUST NOT be the literal `fn` (reserved for section URIs). - For workers in this repo, the router id equals the folder name — a single segment.
