test-analyze

test-analyze is a skill for Claude Code, Codex from cohemm/prism. It costs 96 tokens per session (1,894 once invoked), scanned A, original, MIT.

A live test runner for the prism:analyze skill, which examines real codebases and produces analysis findings. It checks both the workflow and the evidence behind those findings.

In plain words
What is it for?
Use it to run end-to-end tests of prism:analyze, check that JSON output from one phase is read by the next, inspect real verification scores, and confirm that findings without code evidence score low.
Why use it?
It catches broken handoffs between analysis stages and helps prevent unsupported findings from receiving high verification scores.

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-analyze 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 4d 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.

test-analyze: Live Test Runner for prism:analyze

Run live end-to-end tests of the prism:analyze skill with real code analysis, real MCP verification, and automated grading.

All test fixtures for this skill must remain self-contained under skills/test-analyze/:

  • skills/test-analyze/evals/evals.json
  • skills/test-analyze/references/
  • skills/test-analyze/test-results/ when generated

Treat paths in evals/evals.json as relative to this skill directory unless they are explicitly absolute target-codebase inputs.

What This Skill Tests

Three categories of assertions, each verified against real execution artifacts:

  1. Workflow Gates (16 existing assertions) — Phase ordering, agent spawn patterns, tool calls
  2. Producer/Consumer Contracts — JSON files written by one phase are correctly read by the next
  3. Verification Scores — Real prism_interview MCP scores; findings without code evidence get low scores

Execution

Phase T0: Setup

  1. Read test cases from evals/evals.json (relative to this SKILL.md)
  2. Generate a test run ID: test-{short-id} via uuidgen | cut -c1-8
  3. Resolve paths:
    • {skill-dir} = absolute path to this SKILL.md's parent directory
    • {analyze-skill-path} = resolve evals.json analyze_skill_path relative to {skill-dir} → absolute path
    • Ontology scope is auto-resolved by the MCP server from brownfield defaults (no manual mapping needed)
  4. Create workspace: ~/.prism/state/{test-run-id}/
  5. Create results directory: {skill-dir}/test-results/{test-run-id}/
  6. Show user: "Running {N} test cases. Estimated time: ~5-8 min per test case."

Phase T1: Execute Test Cases

For each test case in evals/evals.json:

T1.1: Spawn Analyze Orchestrator

Spawn a background agent that executes the full prism:analyze workflow. The agent must:

  • Read ../analyze/SKILL.md and follow it exactly
  • Use the test case's prompt as the analysis request
  • Use the test case's target_codebase as the code to analyze
  • Use state directory: ~/.prism/state/{test-run-id}/{eval-id}/
  • Auto-approve Phase 0.6 (skip AskUserQuestion — add instruction: "Auto-approve all perspectives without asking the user")
  • Execute Phase 2B verification using real prism_interview + prism_score MCP calls
  • Write all artifacts (seed-analysis.json, perspectives.json, context.json, findings.json, etc.)

Files

What ships with it

3 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.

test-analyze is a skill published in the GitHub repository cohemm/prism (5 stars, last pushed 3mo ago), licensed MIT. It adds 96 tokens to every session and 1,894 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
