claude-skill

claude-skill is a skill for Claude Code from neat-technologies/neat. It costs 0 tokens per session (1,850 once invoked), scanned B, original, Apache-2.0.

A Claude Code skill that connects coding agents to NEAT's live graph of project services and dependencies. NEAT is a system that records how services relate, what happens at runtime, and which policy rules may be violated.

In plain words
What is it for?
Finding root causes, listing downstream effects, inspecting direct or transitive dependencies, comparing code declarations with runtime dependencies, and querying NEAT's instrumentation tools.
Why use it?
It gives agents project context for tracing failures, comparing declared dependencies with observed production behavior, and understanding the impact of a change.

Token cost

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.

Security

Grade B, and why

claude-skill scanned grade B with 1 finding 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (hooks/neat-search-nudge.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

NEAT — Claude Code skill

This skill exposes NEAT's live semantic graph to Claude Code over MCP. Once installed, Claude can ask the running NEAT daemon (neatd) about a project's services, dependencies, recent errors, and policy violations — same as any other agent NEAT supports.

What you get

Sixteen MCP tools, served by @neat.is/mcp over stdio — ten read-only graph queries plus six /neat extend tools for instrumentation. The canonical list lives in MCP_TOOL_NAMES (@neat.is/types); the server registrations are the source for every description below.

Read tools

Tool What it does
get_root_cause Trace a failing node up its dependency graph to the underlying cause. Use when something is breaking and you want the upstream culprit.
get_blast_radius List every node downstream of a node — what would break if it failed or was redeployed.
get_dependencies Transitive outgoing dependencies, BFS to depth N, each carrying distance, edge type, and provenance (EXTRACTED vs OBSERVED).
get_observed_dependencies Only the runtime (OBSERVED via OTel) outgoing dependencies — compare what code declares against what production does.
get_incident_history Recent OTel error events recorded against a node, most recent first.
get_divergences Places where the code (EXTRACTED) and production (OBSERVED) disagree, ranked by confidence × severity. The most NEAT-shaped query — reach for it on "is anything weird?"
get_graph_diff Diff a saved graph snapshot against the current live graph — added/removed/changed nodes and edges.
get_recent_stale_edges Most recent OBSERVED → STALE transitions — integrations that have gone quiet.
check_policies Inspect or dry-run the project's policy.json. Returns current violations, or violations a hypothetical action would cause.
semantic_search Search nodes by natural-language query (embedding vectors when available, substring fallback otherwise).

What ships with it

5 files 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.

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.

claude-skill is a skill published in the GitHub repository neat-technologies/neat (18 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,850 tokens. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
