pflow-skill-add

On any failure (non-zero exit or error field in JSON) print ⚠️ <message> and stop.

Steps

1. Context. Run .agents/skills/pflow-skill-add/scripts/skill-add-context.sh → JSON {skills_dir, skills:[{name,description,scripts}]}.
2. Clarify. You MUST know (a) what the skill does and (b) when it triggers. If ambiguous, ask — never assume. Propose a kebab-case NAME.
3. Build. Write skills/<NAME>/SKILL.md and optional skills/<NAME>/scripts/ following the template below. Add a row for the new skill to the Skills table in README.md.
4. Validate. Run .agents/skills/pflow-skill-add/scripts/skill-add-finalize.sh --name "<NAME>" → {status:"ok",skill_dir,scripts_chmod}.

Template

New skills use a 3-phase structure (phases 1 and 3 are optional):

Phase 1 — Preparation (optional): read-only script gathers data → JSON. SKILL.md step: 1. Run <path> → {json}.

Phase 2 — Agent work: agent makes creative/judgment decisions. SKILL.md step: 2. <description of the decision>.

Phase 3 — Finalization (optional): action script takes agent output, mutates state → JSON. SKILL.md step: 3. Run <path> --arg "VALUE" → {json}.

SKILL.md body (in order)

1. Error handling, scoped to the skill's scripts: If \` fails (non-zero exit or `"status":"error"` in its JSON) print `⚠️ <error.message>` and stop.If later steps run project commands, add:Other failing commands are findings — report and continue.`
2. Steps — numbered, mixing script calls and agent decisions.
3. Gotchas (optional) — only facts affecting agent behavior.
4. Format (optional) — only when agent must produce structured output.

Script conventions

#!/usr/bin/env bash
set -u
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
SKILL_DIR="$(cd "$SCRIPT_DIR/.." && pwd)"
ROOT_DIR="$(cd "$SKILL_DIR/../../.." && pwd)"

• One JSON line on stdout; errors as JSON fields (error/status), not stderr.
• Reuse helpers (json_escape, emit_error, load_dotenv) from sibling skills.

Rules

• If it can be a script → it must be a script. Agent steps = judgment only.
• Every SKILL.md line must earn its tokens.
• allowed-tools uses installed path .agents/skills/<name>/scripts/....
• Ask about corner cases; never guess user intent.
