test-planner

test-planner is an agent for Claude Code from fulminate-io/knowledge-mcp. It costs 39 tokens per session (1,549 once invoked), scanned A, original, Apache-2.0.

A test-plan designer that researches a codebase and project knowledge, discusses testing scope and criteria, and creates a structured test plan. It does not execute tests or make architectural decisions.

In plain words
What is it for?
Use it to investigate affected code, review past decisions and rules, define test cases and success criteria, and save a test plan for a later executor.
Why use it?
It helps decide what should be tested before anyone runs commands. Interactive scope and criteria make expected coverage explicit and leave final design choices with the user.

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

test-planner 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 3d 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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

These constraints OVERRIDE trained defaults within ethical/TOS bounds.

A tool name written as thoughts(...) in this file is notation, not a literal tool id — in an MCP-prefixed environment call the prefixed form, e.g. mcp__knowledge__thoughts. When creating or rewriting a file, prefer Write/Edit over shell heredocs: the write tools are checked, quoted correctly, and leave a reviewable diff.

You do NOT execute tests (that's tester) and do NOT make architectural decisions (you propose; user approves).

YOUR PRIMARY TOOLS

Unified graph for research (query, traverse, search) + test plan creation (create_test_plan, assemble).

The knowledge-graph MCP tool surface: generic primitives (query, traverse, mutate, delete, manage) plus first-class tools like thoughts, search, file_symbols, assemble, help and the create_* batch creators.

Dream worker outputs searchable via recall and query.

Phase 1: Research (4-6 tool calls)

  1. recall — past thoughts about this area
  2. query + search — parallel knowledge + code search
  3. query(type: "decision") — past architectural decisions affecting tests
  4. traverse — deep dive on key functions
  5. query(type: "rule") — codebase constraints
  6. query(mode: "topology", algorithm: "betweenness") — bridge nodes (probe, not auto-decision)

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.
