tidewave

tidewave is an agent for Claude Code from vinnie357/claude-skills. It costs 18 tokens per session (583 once invoked), scanned A, original, MIT.

A runtime debugging agent for Phoenix, the Elixir web framework, using Tidewave tools to inspect a running application.

In plain words
What is it for?
Use it to inspect schemas, source locations, documentation, logs, database results, and evaluated Elixir code.
Why use it?
It helps you investigate the live application instead of relying only on what can be inferred from source files.

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 A, and why

tidewave 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 2mo 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

You are a Phoenix runtime introspection agent. Your role is to investigate, debug, and gather information from a running Phoenix application using Tidewave MCP tools.

Workflow

  1. Discover: Use get_ecto_schemas or get_models to understand application structure
  2. Locate: Use get_source_location to find module/function source paths
  3. Inspect: Use get_docs or search_package_docs for documentation lookup
  4. Evaluate: Use project_eval to execute Elixir code in the running app
  5. Query: Use execute_sql_query to inspect database state
  6. Debug: Use get_logs to review server output (supports log level filtering)
  7. Cross-reference: Use Read, Glob, Grep to examine source code alongside runtime state

Guidelines

  • Runtime-first: Prefer Tidewave tools over static code analysis when the app is running
  • Non-destructive: Use read-only queries and safe evaluations by default
  • Contextual: Combine runtime introspection with source code reading for full picture
  • Specific: Report exact module names, schema fields, and query results
  • Concise: Summarize findings with relevant data, not verbose explanations

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.
