TinyFish Cookbook is a collection of example applications, recipes, and automations built with TinyFish, a web service that lets AI agents search the live web, read pages, and perform browser-based tasks. Developers use it to learn how to build web agents and connect them with workflows such as research, monitoring, and data collection. The catalogue entries provide agent skills and integrations for working with these examples and TinyFish endpoints.
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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high YARA Match · line 10 YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
- low Excessive Agency · line 327 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
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 | $0.00158 | $0.05650 |
| Opus 5.5 | $0.00063 | $0.02260 |
| Sonnet 5.5 | $0.00032 | $0.01130 |
| Haiku 4.5 | $0.00016 | $0.00565 |
Grade A, and why
kb-builder 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 786 lines — stays where its author put it; the contents beside it link to each section on GitHub.
KB Builder
Build a topic-specific markdown knowledge base by using TinyFish to browse public web sources and extract structured evidence.
This skill is for builder knowledge bases, not personal journals and not direct code generation.
The output is a folder you can drop into Obsidian immediately, and update later without starting over.
Core principle
Do not produce a pile of source summaries.
The KB should help the reader understand:
- the core mental model
- the main approaches or schools of thought
- what is foundational vs derivative
- what actually matters
- what is unresolved
- what to read first if they want genuine understanding
If the output only says what each source said, the skill has failed.
Pre-flight check
Run both checks before any TinyFish call:
which tinyfish && tinyfish --version || echo "TINYFISH_CLI_NOT_INSTALLED"
tinyfish auth status
If TinyFish is not installed, stop and tell the user:
npm install -g @tiny-fish/cli
If TinyFish is not authenticated, stop and tell the user:
tinyfish auth login
Do not continue until both checks pass.
Scope
- Allowed: public web pages, public GitHub repos, public papers, public docs, public datasets, public blog posts
- Not allowed: private sources, local private files, authenticated dashboards, chat logs, email, Slack, or anything the user cannot access publicly
- Primitive: use explicit
tinyfish agent runcommands - Output shape: always
index.md,sources.md,audit.md, andmanifest.json; everything else is dynamic
Input modes
You support two modes:
- Topic only
- Example:
Build me a knowledge base on web agent frameworks
- Example:
- Topic + starter URLs
- Example:
Build me a knowledge base on web agent frameworks and start from these URLs: ...
- Example:
- Update an existing KB
- Example:
Update my knowledge base on Kolmogorov-Arnold Networks with these new URLs: ...
- Example:
- Trace mode
- Example:
Build me a knowledge base on browser agents --trace
- Example:
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.

kb-builder is a skill published in the GitHub repository tinyfish-io/tinyfish-cookbook (2,261 stars, last pushed 11d ago), licensed MIT. It adds 158 tokens to every session and 5,650 once invoked, about $0.0006 per session on Opus 5.5. 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.
