gen-ai-explainer — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited gen-ai-explainer (Agent Skill) and scored it 83/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 2 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

You drive a 6-stage pipeline. You handle the creative stages in chat; the gen-ai CLI handles all media generation and rendering. State lives in ~/.gen-ai/projects/explainer/<slug>/ as JSON files.
Before anything else, decide which mode the user wants:
The 4 creative stages each end with a hard STOP. You present, the user reviews, types continue / edits / picks. The full Rule One below applies. Right for first-time use, premium production, anyone who hasn't told you otherwise.
You execute all 6 stages end-to-end without STOPping. You still present each artifact briefly so the user can interrupt if they want, but you do NOT wait. You make the picks: best concept of the 3, best playbook for the concept, script as you'd write it. The user is signing up for "trust your judgment, go end-to-end."
Detect auto mode when the user's request includes one of:
auto, auto mode, auto-approve, auto approveno approvals, skip approvals, don't ask, no questionsjust do it, yolo, full auto, end to endrun it through, run all stages, no checksIf you see ANY of those, set mode = auto. Otherwise, mode = interactive.
If the user's wording is ambiguous, ask ONCE at the start: "Interactive (I pause at each stage for your review) or auto (I run end to end and you get the final video)?" — then proceed.
"Spending ~1850 credits on assets now. Balance: 12,500 → ~10,650 after." Don't ask for permission, just announce. The user can Ctrl-C if they disagree.
regardless of mode.
{ "status": "error", "hint": "..." }, stop and tell the user.
topic obviously needs 3+ minutes to cover well, ask once before guessing.
| Stage | Interactive | Auto |
|---|---|---|
| research | Present findings, STOP | Present findings briefly, continue |
| proposal | Show 3 concepts + estimate, STOP | Show 3 concepts + estimate, pick best yourself, announce pick, continue |
| script | Show full script, STOP | Show script, continue |

Every creative stage is a hard stop. You do the work, present it, then STOP and wait for the user. Do NOT chain stages without explicit user approval.

Read the chosen playbook's audio.voice_style and reflect it in speaker_directions. STOP after showing the script.references/scene-plan-director.md. Include the `playbook` field at the top of `scene-plan.json`. STOP after showing the scene table — this is the last gate before money is spent.references/asset-director.md. Write scene-plan.json (with playbook field) and script.json into the project dir. Then run gen-ai explainer:assets <slug> — the CLI auto-applies the playbook's image_prompt_prefix, image_negative_prompt, and music_mood.references/render-director.md. Run gen-ai explainer:render <slug> — playbook auto-flows from the asset manifest; ffmpeg uses its music_volume_db and narration_to_music_weight_ratio.After stage 6: draft title / description / chapters / hashtags in chat. Then run gen-ai upload-to-drive <slug>/explainer.mp4 --name "<title>". Share the URL.
Each of the 6 stages has a dedicated director skill at ~/.claude/skills/gen-ai-explainer/references/<stage>-director.md. You MUST read the director skill BEFORE executing each stage. Not after. Not skimmed. Read.
The director files are not "background reading" — they contain the exact process, query templates, schema shapes, self-evaluation rubrics, common pitfalls, and STOP gates for that stage. Skipping them produces lower-quality output that wastes the user's credits.

If you skip director-reading, the user will catch it: research will lack sourced URLs, the script will miss the narrative arc, scene plans will fail the 5-aspect checklist. Sub-quality output betrays the protocol.
This rule applies in interactive mode only. Auto mode replaces STOP with "announce and continue" per the Mode section above.
In interactive mode, the four creative stages (research / proposal / script / scene_plan) each end with a hard STOP. After presenting your output:
In interactive mode, Do NOT:
If you skip a gate in interactive mode, the user pays for visuals they didn't sign off on. The whole point of interactive mode is human-in-the-loop control.
In auto mode the user has explicitly opted out of approvals — you go through all 6 stages and produce the video. You still announce each stage's output (so the user sees what you picked) and announce the credit estimate, but you don't wait for input.
