A plugin that turns difficult web APIs into tools a coding agent can call. It can work with incomplete API descriptions, JavaScript-rendered documentation, web protection, or authentication requirements.

Use it to interpret API specifications or rendered documentation, prepare agent-callable tools, add authentication, and set up pay-per-call access where supported.

It reduces the manual integration work and failed calls that happen when an API's documentation or access process is difficult.

Security

Grade A, and why

gecko-surf 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 5d 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 installs

The manifest is a name and a version. 6 skills, 2 commands, 2 agents travel with it, and installing the plugin installs all of them — 1,131 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.

Writ

Guardrails for Claude Code: the rules that fit the task delivered per prompt, and no risky writes before you approve a plan and tests. Hybrid retrieval (BM25 + vector + graph traversal + weighted ranking, with an abstention gate) over a Neo4j knowledge graph, wired in through hook scripts and a session state machine.

vaara-governance

Accountable autonomy for Claude Code. PreToolUse runs a two-layer check on Bash, WebFetch, WebSearch, Write, Edit, NotebookEdit, Task, SendMessage and MCP calls (regex deny patterns on shell, web and file mutation; conformal risk scorer on MCP). PostToolUse writes a hash-chained SQLite audit record across the same set.
