Optimize generative image/video/audio workloads — inference step counts, distilled/turbo model variants, generate-small-then-upscale strategies, batching, seed reuse, and cache-vs-regenerate policy for repeated assets. Use this skill whenever the user runs diffusion or generative media models (Stable Diffusion, image/video/audio generation APIs), shares generation configs, or asks how to cut the cost or footprint of AI-generated media. Part of Lean Agentic AI Skills; emits lean-findings.json.

GenAI Media Optimizer

Producer/advisor skill. Input: generation configs (model, steps, resolution, scheduler, batch settings), usage patterns (volumes, repeat rates), quality bar. Output: lean-findings.json + a generation-pipeline design when asked.

Text models meter in tokens; media models meter in denoising steps × pixels. The dials are different from the LLM family and usually left at tutorial defaults.

Subject type: emit subject.type: "ai-inference" in findings.

Signatures

Step-count defaults — 50-step sampling where modern schedulers hold quality at a fraction of the steps; per-asset-class step tuning absent. High: compute scales ~linearly with steps. Fix: scheduler upgrade + stepped-down A/B on the user's own quality bar.
Full-size generation for small display — generating at maximum resolution for thumbnails, previews, or mobile-only surfaces. High: cost scales super-linearly with resolution. Fix: generate at display size; generate-small-then-upscale (a cheap upscaler pass) for the subset needing large output.
Foundation model where distilled serves — full-size models for high-volume, style-consistent production work where distilled/turbo/LCM variants hold the bar. High at volume; validate on the user's eval set (route the tiering method to model-right-sizer patterns; record the media finding here).
Regenerating the repeatable — same prompt+params generating fresh assets on every request (avatars, backgrounds, product variants). High. Fix: content-addressed cache keyed on (model, prompt, params, seed); pairs with llm-cache-designer mechanics.
No draft-vs-final tiers — iteration/preview loops running at final quality; users burning full-cost generations to explore. Medium-high. Fix: low-step draft mode for exploration, full quality only on commit.
Unbatched generation — sequential single-image calls where batching amortizes model load/warm state (self-hosted). Medium.
Video where image serves — animated outputs for surfaces a still would serve; frame counts/fps beyond display need. Medium.
Abandoned outputs stored hot — generation history retained forever in premium storage; route lifecycle to storage-lifecycle-audit, record the generation-policy finding here.

Honesty rules

Step counts, resolutions, and generation volumes are countable — report them. Quality is the user's judgment: every reduction ships with an eval instruction on their own content, never a blanket "quality is unaffected". Per-generation energy varies by hardware and model — directional language only; measurement pointer: CodeCarbon around the generation loop for self-hosted setups.

Cost signal (countable)

Cost drivers: denoising-steps × resolution × generation volume. All three are countable from configs and usage stats. cost_signal.observed names them; direction stays qualitative because per-step energy varies by hardware.

Not this skill's job

Text/LLM optimization (model-right-sizer, prompt-carbon-optimizer), where generation runs (inference-placement-advisor), delivery of the generated media (video-streaming-optimizer, web-carbon-audit).

agentic-loop-auditor

navveenb/lean-agentic-ai-skills

Audit agent frameworks and agentic workflows for token-burning loop pathologies — unbounded retries, excessive planning depth, tool-call thrashing, context snowballing, missing loop budgets and kill switches. Use this skill whenever the user shares agent configs or traces (LangChain/LangGraph, CrewAI, AutoGen, custom loops), complains an agent is slow or expensive, or is designing any autonomous/multi-step agent.

ai-eval-efficiency-audit

navveenb/lean-agentic-ai-skills

Audit AI evaluation infrastructure for wasted compute — full benchmark suites re-run on unchanged cases, LLM-as-judge grading without caching, oversized judge models, redundant eval passes per commit, and missing result reuse. Use this skill whenever the user shares eval harness configs or CI eval steps, complains that evals are slow or expensive, mentions LLM-as-judge costs, or runs benchmark suites on every change.

api-efficiency-audit

navveenb/lean-agentic-ai-skills

Audit API design for chattiness and over-fetching — REST endpoints requiring N calls per screen, GraphQL resolvers with N+1 fan-out, default-everything payloads, missing pagination and field selection, provider-side polling where webhooks serve, and uncompressed responses. Use this skill whenever the user shares API schemas (OpenAPI, GraphQL SDL), resolver code, endpoint designs, or asks why clients make too many calls or payloads are heavy.

caching-strategy-designer

navveenb/lean-agentic-ai-skills

Design caching layers so work is done once, not per request — HTTP/CDN caching, application-level caches (Redis/Memcached), computed-result caching, and cache-invalidation strategy. Use this skill whenever the user wants to add caching, asks why the same work is recomputed, designs a read-heavy system, or an audit skill (db-efficiency-audit, web-carbon-audit) flags uncached repeated work. Part of Lean Agentic AI Skills; emits a cache design plus lean-findings.json.

navveenb/lean-agentic-ai-skills

Design time-shifting of flexible workloads (batch jobs, CI, training, backups, crons) to hours and regions when grid electricity is cleanest, using carbon-intensity signals like Electricity Maps, WattTime, or the Carbon Aware SDK. Use this skill whenever the user mentions carbon-aware computing, scheduling flexible/deferrable jobs, demand shifting, running workloads when energy is clean, or asks how to reduce the carbon intensity (not just amount) of their compute.

Design per-feature and per-service efficiency budgets — page-weight budgets, token budgets per AI feature, query budgets per endpoint, GPU-hour budgets per training project — with owners, review checkpoints, and enforcement hooks. Use this skill whenever the user wants sustainability targets for teams, asks how to keep efficiency from regressing organizationally, mentions performance-budget-style governance for carbon/energy, or is setting engineering standards.
