denis 0b901cf2f9 feat: KeiSeiKit v0.1.0 — initial public release
Generic Constructor-Pattern agent kit for Claude Code. Zero personal data,
fully English, MIT-licensed.

Contents:
- 34 reusable blocks (baseline, rules, stack/deploy/domain/api/scraper)
- 14 cross-project agent manifests (code/ml/infra/researcher/critic/...)
- 6 portable skills (/new-agent, /research, /test-gen, /debug-deep, /pr-review, /refactor)
- Rust assembler (single binary, ~500 KB)
- 3 hooks (auto-reassemble, pre-commit validate, no-hand-edit)
- install.sh (idempotent, cargo-builds on first run)
- MIT LICENSE

All 6 sanity greps pass: 0 Russian text, 0 specific project names,
0 incident numbers, 0 user paths, 0 hardcoded IPs, 0 API keys.

cargo check + assemble --validate: both pass on 14 manifests.

API — Apify (web scraping platform)

Live pricing: WebFetch https://apify.com/pricing before any run >$5. Treat the table below as a starting sketch and always re-verify on the live pricing page.

Platform plans (sample — re-verify on live pricing page):

Plan $/mo Credits CU cost Max RAM Retention
Free $0 $5 $0.30 4-8 GB 7d
Starter $49 $49 $0.30 32 GB 14d
Scale $199 $199 $0.25 128 GB 21d
Business $999 $999 $0.20 256+ GB 31d

CU (Compute Unit) formula: CU = Memory(GB) × Duration(hours). Browser scraper ≈ 300 pages/CU; HTTP scraper ≈ 3000 pages/CU. Most actors 0.1-5 CU/run.

Per-actor rates (sample — re-check pricing page before any batch):

Platform Best actor $/1K Risk Free alternative
YouTube apidojo/youtube-scraper $0.50 LOW YouTube Data API v3 (FREE, 10K units/day)
LinkedIn harvestapi/linkedin-profile-scraper $4 (no email) / $10 (email) HIGH linkedin_scraper (Python)
Instagram apify/instagram-scraper (official) $2.30-2.60 VERY HIGH Instaloader
Instagram apidojo/instagram-scraper (3rd party) $0.50 VERY HIGH
Facebook apify/facebook-posts-scraper $5-8 VERY HIGH facebook-scraper
Telegram via Apify $1-3 LOW Telethon/Pyrogram (FREE, MTProto)

Prefer free path when available — Telethon (Telegram) and YouTube Data API v3 are 100% FREE and fully featured.

Proxies:

  • Datacenter — included in plan; $0.6-1.0/IP overage. Blocked by IG/FB on first hit.
  • Residential — $7-8/GB. Required for Instagram/Facebook. GDPR risk for EU targets (BGH Germany Nov 2024: €100/user scraping compensation).
  • SERP — $2.50/1K.

Webhooks: POST on ACTOR.RUN.SUCCEEDED / .FAILED → your endpoint receives runId, datasetId. Use for pipelines; poll only for manual one-offs.

Input schema validation: every actor has a JSON schema (input_schema.json). Validate inputs client-side before POST — failed inputs still eat CU in the startup phase.

Legal landscape: hiQ v. LinkedIn (2022) CFAA ≠ public data; Meta v. Bright Data (2024) Meta lost; BGH Germany Nov 2024: GDPR Art. 82 → €100 per scraped user. All 6 major platforms' ToS prohibit scraping (contractual, not criminal).

LinkedIn HIGH RISK: harvestapi no-cookie actors are safer ($4-10/1K). Cookie-based (curious_coder) = ban + ToS exposure. Max 500 profiles/day deep. Always legal review before EU LinkedIn runs.

Forbidden: LinkedIn batch without legal sign-off (GDPR + ToS); residential proxies against EU targets without documented consent basis; batch runs without per-item cost estimate to cost-guardian; using main personal account for any cookie-based actor (curious_coder line); launching an actor before validating input against its input_schema.json; paying Apify for Telegram when Telethon is free.
