meta-kid-project-planner

Junior & guardian persona meta-skill. Turns a child's project idea — "我要做火山", "I want to build a model rocket", "open a YouTube channel about insects" — into a kid-friendly step plan PLUS a parent-friendly oversight pack. The two audiences are concatenated in one markdown deliverable with clear ## 👦 For You (the kid) / ## 👨‍👩‍👧 For the Grown-up sections — a markdown-level workaround for the proposed audience: primitive (portfolio design §4.2).

Composition philosophy — multi-skill bundled orchestration

This meta-skill uses only OpenSquilla-bundled atomic skills plus the five built-in step kinds — no external dependencies. The DAG calls into 5 distinct bundled atomic skills:

Step kinds used: llm_chat, llm_classify, user_input, skill_exec, agent.

Vocab card generation is a plain llm_chat step (vocab_cards) grounded in outputs.outline_steps + outputs.material_list — the LLM produces 6 age-appropriate cards directly. No external flashcard skill is required.

Bilingual rendering for LANGUAGE: mixed is also prompt-side in the relevant steps — no separate translation skill required.

Safety design

Three layers of guardrail:

1. preferences step rejects clearly inappropriate topics by setting PROJECT_SAFE: no in its contract. This is prompt-side; cannot be bypassed by clever phrasing because the model's response is constrained to the return format.
2. feasibility classifier produces INAPPROPRIATE for any topic that involves weapons, dangerous chemistry, fire-without-adult, self-harm-adjacent themes. INAPPROPRIATE short-circuits the project pack and routes to redirect_unsafe.
3. redirect_unsafe produces a gentle, non-shaming redirect with 3 alternative project ideas that scratch the same itch safely.

The skill never silently degrades safety — if the topic is unsafe, the deliverable IS the redirect, with PACK_DELIVERED: no_safety_redirect.

Honest limitations (first-wave)

• audience: is markdown sections, not real two-principal output. When the proposed primitive ships, the kid section can go to a child-facing surface while the parent section goes to the guardian's channel, separately.
• No persistence of past projects. Each invocation is independent — without state:, the skill cannot remember which projects the child has already done.
• Vocab cards do not feed an FSRS deck. The vocab_cards step emits a one-shot card list; integrating with a spaced-repetition state machine is reserved for a future meta-spaced-rep-coach.
• Topic safety relies on prompt-side guardrails. A future dedicated safety-policy step kind would be more robust than prompt-side judgment under adversarial inputs.
