fix(skills): accept allowed-tools as a comma string, not only a sequence

[nocstah]

Summary

• Fixes skills that declare allowed-tools as a comma-separated string (Claude Code's convention) failing to parse, which silently drops their tools and surfaces as "tool not available" at run time.
• Adds a string-or-sequence deserializer so allowed-tools accepts either a YAML list or a comma-joined scalar, plus a tools alias.
• Affects popular community catalogs (e.g. antigravity-awesome-skills) that ship the scalar form.

Problem

WorkflowFrontmatter::allowed_tools deserializes as Vec<String>. A skill written as:

allowed-tools: Bash, Read, Grep, Skill, WebFetch

fails with invalid type: string, expected a sequence, logged as [skills] failed to parse frontmatter. The frontmatter is rejected and the skill's declared tools are dropped, so running that skill reports its tools (Bash, etc.) as unavailable. This is common: skills authored for the claude CLI use the scalar form, and OpenHuman refreshes such catalogs by default.

Solution

• de_string_or_seq: an untagged Seq(Vec<String>) | Str(String) deserializer. A scalar is split on commas and trimmed; empties dropped. A YAML list passes through unchanged.
• Add alias = "tools" so the common tools: key maps to the same field.
• No change to the serialized (write) form.

Submission Checklist

• Tests added or updated — allowed_tools_accepts_yaml_sequence, allowed_tools_accepts_comma_string, allowed_tools_accepts_tools_alias, allowed_tools_defaults_empty_when_absent (happy + the previously-failing scalar edge case).
• Diff coverage ≥ 80% — the changed lines are the deserializer + field attrs, all exercised by the new tests. pnpm test:rust passes locally.
• Coverage matrix updated — N/A: parser-tolerance fix, no feature row change.
• All affected feature IDs listed under ## Related — N/A.
• No new external network dependencies introduced.
• Manual smoke checklist — N/A: does not touch release-cut surfaces.
• Linked issue closed via Closes #NNN — N/A (no dedicated issue; addresses the tool-availability observation noted in [claude-code] Chat fails permanently — driver resumes a session it never created ("No conversation found") #5648).

Impact

• Skills subsystem, parse-time only. More skills load successfully; no change for skills that already used a YAML list. No migration, no new deps.

📝 Walkthrough

Walkthrough

WorkflowFrontmatter.allowed_tools now accepts YAML sequences and comma-separated strings. The parser trims values, removes empty entries, preserves aliases, and defaults missing fields to an empty vector. Tests cover each supported input form.

Changes

Allowed tools deserialization

Layer / File(s)	Summary
Allowed tools parsing and validation src/openhuman/skills/ops_types.rs	allowed_tools now uses de_string_or_seq. The helper accepts sequences or comma-separated strings, trims entries, removes empty values, and retains the tools alias. Tests cover supported inputs and the absent-field default.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e03c0

This change broadens skill frontmatter parsing to accept comma-separated tool names and the tools alias without expanding tool authority. No actionable merge-blocking risk remains beyond normal review and checks.

Poem

A rabbit parsed the tools with care,
From YAML lists or strings laid bare.
Empty crumbs hopped away,
Aliases joined the play,
And defaults kept the fieldship fair.

Add regression coverage for the remaining input variants.

The tests cover clean comma-separated values, but not trimming or empty-token removal. Add a case such as allowed-tools: " Bash, , Read, " and assert ["Bash", "Read"]. Also add a case for the retained allowed_tools alias.
