Growth Lab is an open-source growth system that uses coding agents to understand a product, research markets, execute growth activities, and learn from the results. It is designed for teams that want to manage growth work across channels such as SEO and Xiaohongshu through natural-language collaboration, persistent product context, and recorded outcomes. Catalogue add-ons define parts of its product models, research methods, execution workflows, and agent operation.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00325 |
| Opus 5 | $0.00028 | $0.00162 |
| Sonnet 5 | $0.00011 | $0.00065 |
| Haiku 4.5 | $0.00006 | $0.00032 |
Grade A, and why
media-crawler-douyin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Douyin collection
Follow media-crawler. Require purpose, keywords/links, sample size, date window, comments/media scope, and destination under the invoking Model's Memory.
Build queries across problem, category, and audience. Run --platform dy --type search serially; shortlist on topical relevance, hook/format diversity, recency and engagement. Search cards are discovery evidence only. For exact enrichment, set DY_SPECIFIED_ID_LIST in config/dy_config.py; it accepts full video URLs, URLs containing modal_id, short links, or video IDs. For creators set DY_CREATOR_ID_LIST to profile URLs or sec_user_id, then use --type creator. PUBLISH_TIME_TYPE controls the upstream publish-time filter.
Enable comments or ENABLE_GET_MEIDAS only for the shortlist, then run --type detail. Verify canonical video ID, author, caption, publish time, engagement, media mapping, comment coverage and any truncation. Deduplicate by video ID and retain the discovery query. Stop on login/risk control; never loop retries.
Return raw/copied paths, query and selection rationale, search/detail/creator counts, comment/media coverage, time and upstream commit.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

media-crawler-douyin is a skill published in the GitHub repository tsingyuai/growth-lab (1,998 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 57 tokens to every session and 325 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
