From 8b185ae312806e544c7a0f2518c938a505d4b5ce Mon Sep 17 00:00:00 2001 From: Natalia Venditto Date: Sat, 27 Jun 2026 11:28:57 +0200 Subject: [PATCH 01/10] feat(skills): read script-carrying skills + add skill_run_script orchestration tool MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - extend SkillIndexEntry/SkillSummary with optional execution (entry, runtimes, capabilities, timeoutMs) parsed from flat execution_* frontmatter fields; absent fields → execution: undefined (backwards-compatible) - folder-loader detects script.js sibling via sub-folder listing; populates execution on SkillSummary only when both execution_entry frontmatter and script.js are present - add skill_run_script client-executed tool (no execute fn) registered in CANVAS_CLIENT_ONLY_TOOLS; args carry only { skillId, input } — agent never passes capabilities or eligibility hints; client (da-nx) resolves those from the trusted manifest - update buildSkillsPromptSection to split prose vs script-runnable skills and instruct the model to call skill_run_script with { skillId, input } Agent reads/indexes only (no execution). The execution-metadata frontmatter parser is the reusable seam for future AO marketplace integration, which is deferred to avoid colliding with the in-flight feat/ao-harness-adapter branch that owns src/ao/.

To invoke one, call the \`skill_run_script\` tool with \`{ skillId, input }\` where \`input\` matches the shape documented in the skill's instructions. Do NOT include capabilities or execution metadata in the call — the client resolves those independently.\n\nWhen a script-skill needs an attached file as input, pass \`input: { attachmentRef: "" }\` (plus any other params the skill documents), where \`\` is the attachment id shown in the attached files list (e.g. \`[abc123]\` → \`"abc123"\`). Do NOT put file bytes or base64 data in the arguments — the client resolves the reference to the file contents.\n${lines}`; } section += diff --git a/test/prompt-builder.test.ts b/test/prompt-builder.test.ts index 5116cb3..712d3f4 100644 --- a/test/prompt-builder.test.ts +++ b/test/prompt-builder.test.ts @@ -158,6 +158,22 @@ describe('buildSystemPrompt with skills', () => { const prompt = buildSystemPrompt(undefined, null, { skills: [] }); expect(prompt).not.toContain('Available Skills'); }); + + it('includes attachmentRef guidance in the script-runnable skills section', () => { + const skillsIndex = { + skills: [ + { + id: 'import-csv', + title: 'Import CSV', + execution: { type: 'script' as const, scriptUrl: 'https://example.com/script.js' }, + }, + ], + }; + const prompt = buildSystemPrompt(undefined, null, skillsIndex); + expect(prompt).toContain('Script-Runnable Skills'); + expect(prompt).toContain('attachmentRef'); + expect(prompt).toContain('file bytes or base64'); + }); }); describe('buildSystemPrompt with agent', () => { From 7a9c3d22b5df810b4a60e72600e74081ecffd1f2 Mon Sep 17 00:00:00 2001 From: Natalia Venditto Date: Mon, 29 Jun 2026 12:35:39 +0200 Subject: [PATCH 05/10] test(skills): characterization net freezing existing skill load/read/save behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds test/skills/skill-loading.characterization.test.ts with 31 tests covering behaviors not asserted in the existing test files: - loadSkillsIndexFromFolders: [a-z0-9-]+ name regex (uppercase/underscore exclusion), all-unreadable folder (404 per file) → source=folder no sheet fallback, no execution field on any folder skill, fallback=false + 4xx folder → source=none - loadSkillBodyFromFolder: non-404 getSource error falls to sheet (bug characterization) - loadSkillsIndex: source=site vs none, title from plain first line vs heading, skips blank leading lines, id/value/body column variants, .md key suffix stripping - loadSkillContent: id column, value/body columns, .md suffix lookup normalization, getSiteConfig error → null, trimmed return value - saveSkillContent: creates skills sheet when absent, update vs create dedup, preserves/sets status, 404 config starts from {}, empty id error, .md id stripping, total count updated on append Co-Authored-By: Claude --- .../skill-loading.characterization.test.ts | 639 ++++++++++++++++++ 1 file changed, 639 insertions(+) create mode 100644 test/skills/skill-loading.characterization.test.ts diff --git a/test/skills/skill-loading.characterization.test.ts b/test/skills/skill-loading.characterization.test.ts new file mode 100644 index 0000000..a9be418 --- /dev/null +++ b/test/skills/skill-loading.characterization.test.ts @@ -0,0 +1,639 @@ +/** + * Characterization tests — frozen behavior of existing skill load/read/save for PLG customers. + * Do NOT change assertions without a deliberate migration decision. + * + * Cross-reference: many behaviors are already asserted in: + * - test/skills/folder-loader.test.ts (loadSkillsIndexFromFolders, loadSkillBodyFromFolder) + * - test/skills/loader.test.ts (loadSkillsIndex, loadSkillContent, saveSkillContent) + * + * This file covers only the gaps not present in those files. + */ + +import { describe, it, expect, afterEach } from 'vitest'; +import { + loadSkillsIndexFromFolders, + loadSkillBodyFromFolder, + _fallbackConfig, +} from '../../src/skills/folder-loader.js'; +import { loadSkillsIndex, loadSkillContent, saveSkillContent } from '../../src/skills/loader.js'; +import type { DAAdminClient } from '../../src/da-admin/client.js'; + +// --------------------------------------------------------------------------- +// Shared mock helpers +// --------------------------------------------------------------------------- + +type FolderClientOpts = { + listResponse?: unknown; + listError?: { status: number }; + listByPath?: Record; + sourceByPath?: Record; + configSkills?: { + key?: string; + id?: string; + content?: string; + value?: string; + body?: string; + status?: string; + }[]; +}; + +function mockFolderClient(opts: FolderClientOpts = {}): DAAdminClient { + return { + listSources: async (_org: string, _site: string, path: string) => { + if (opts.listByPath && path in opts.listByPath) { + return opts.listByPath[path] as ReturnType; + } + if (opts.listError) throw opts.listError; + return opts.listResponse ??

charset=UTF-8 Content-Transfer-Encoding: 8bit - define SkillMarketplaceProvider interface (listSkills, getSkillManifest, getScript) + SkillManifest type in src/marketplace/provider.ts - implement GitHubMarketplaceProvider in src/marketplace/gh-provider.ts — moves all existing gh-skills fetch logic behind the interface; constructor takes { owner, repo, branch, path } so any GH-hosted marketplace can be wired in without code changes - add AOMarketplaceProvider stub (src/marketplace/ao-provider.ts) — returns canned data, no real network call; proves the interface is swappable - introduce MARKETPLACES registry + providerFor factory in gh-skills.ts — single source of truth for active sources (future: driven by config sheet/UI); buildMarketplaceSkillsIndex iterates providers, concatenates + dedupes by id - add provider conformance suite (test/marketplace/provider-conformance.test.ts) — identical assertions run against both GitHubMarketplaceProvider and AOMarketplaceProvider, proving any conforming provider can be swapped in - add MARKETPLACES/providerFor/merge tests (test/marketplace/marketplace-config.test.ts) - all 393 tests pass;
