Jonathan Hefner debfb29c8e Fix allowed-tools to use spec-compliant space-delimited strings (#139)
* Fix `allowed-tools` to use spec-compliant space-delimited strings

Per the agentskills.io specification, `allowed-tools` must be a single
string of space-delimited patterns, not a YAML list. Converted all 23
SKILL.md files from the `- Item` list format to the correct
`"Item1 Item2"` string format. Also updated the frontmatter examples in
CLAUDE.md and the workflow-skill-design skill template to match.

* Fix remaining allowed-tools format in firebase-apk-scanner and workflow-skill-design docs

- Convert firebase-apk-scanner from comma-separated to space-delimited
- Update anti-patterns.md and tool-assignment-guide.md examples from YAML lists to space-delimited strings
- Remove unnecessary quotes from SKILL.md template placeholder

* Cover commands, new SKILL.md files, and fix template placeholder

Extends the previous spec-compliance fixes:

* Convert command frontmatter (commands/*.md) — per Claude Code
  docs, command files use the same frontmatter as skills, so the
  same space-delimited rule applies.
* Convert three SKILL.md files added since the original PR:
  mutation-testing, trailmark-structural, trailmark-summary.
* Fix the placeholder in the workflow-skill-design template.
  The previous "[minimum tools needed, space-delimited]" was YAML
  flow-sequence syntax, which parses as a list — the opposite of
  what the placeholder claims. Replaced with a concrete-looking
  space-delimited example plus a comment.

Zeroize-audit agent files still use `allowed-tools:` in YAML list
form. They are intentionally excluded: per the project's own docs
(workflow-skill-design references), agents declare tools with
`tools:` (not `allowed-tools:`). Fixing those requires changing
the field name as well as the format and is out of scope for this
PR.

* zeroize-audit agents: switch allowed-tools to tools

Subagents declare their tool allowlist via `tools:` (comma-separated),
not `allowed-tools:` — see Claude Code's subagent docs and this
repo's own designing-workflow-skills/SKILL.md:47:

> Skills use `allowed-tools:` in frontmatter. Agents use `tools:`
> in frontmatter.

Before this change, the zeroize-audit agents declared their tool list
under `allowed-tools:`, which Claude Code does not read for subagents.
The field was effectively a no-op; the spawned agents had no tool
restriction enforced.

Renames the field on all 11 agents to `tools:` and reformats the YAML
list as comma-separated to match the documented format and existing
agents elsewhere in the repo (e.g. function-analyzer.md,
spec-compliance-checker.md). Tool sets are unchanged.

Behavior change: tools now actually constrain what each spawned agent
can call. The lists are the ones the original author intended.

* skill-improver: convert command allowed-tools to space-delimited

The two command files in plugins/skill-improver/commands/ still used
the JSON flow-array format (`allowed-tools: ["..."]`), which the rest
of this PR converted everywhere else. Convert them to the spec-compliant
space-delimited string form for consistency.

Iteratively reviews and fixes a Claude Code skill until it meets quality standards. Triggers on 'fix my skill', 'improve skill quality', 'skill improvement loop'. <SKILL_NAME_OR_PATH> [--max-iterations N] Bash(${CLAUDE_PLUGIN_ROOT}/scripts/setup-skill-improver.sh:*) Task Read Edit Write Glob Grep

Skill Improver

Step 1: Resolve Skill Path

The user provided: $ARGUMENTS

Resolution rules:

  1. If input ends with /SKILL.md and file exists, use directly
  2. If input is a directory containing SKILL.md, use that path
  3. Otherwise, search for matching skills:
Glob(pattern="**/SKILL.md")

Filter results to find skills matching the user's input (by skill name or path substring).

  • Multiple matches: Ask the user to choose
  • No matches: Report available skills
  • Single match: Proceed with that path

Store the resolved absolute path to the skill directory in RESOLVED_SKILL_PATH.

Step 2: Initialize the Loop

Run the setup script with the resolved path:

"${CLAUDE_PLUGIN_ROOT}/scripts/setup-skill-improver.sh" "<RESOLVED_SKILL_PATH>" [--max-iterations N]

Substitute <RESOLVED_SKILL_PATH> with the actual path. Add --max-iterations N only if specified.

Step 3: Follow the Skill Methodology

Apply the skill-improver:skill-improver skill to iteratively improve the target skill. The loop continues automatically via the stop hook until completion.
