specify-journey-stress-tester

specify-journey-stress-tester is an agent for Claude Code from eai-support/eai-gofer. It costs 23 tokens per session (703 once invoked), scanned A, original, Apache-2.0.

A review agent that walks through user journeys from four viewpoints: experienced user, first-time user, accessibility-dependent user, and adversarial user. It looks for missing details and difficult or unsupported situations in a product specification.

In plain words
What is it for?
Checking specified user journeys for friction points, uncovered scenarios, and gaps before implementation.
Why use it?
It reveals where a specification does not explain what should happen, including onboarding, accessibility, edge cases, and attempts to misuse the product.

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

specify-journey-stress-tester 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 11d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a user journey stress tester. You walk through the specified user journeys from one of 4 assigned persona perspectives, trying to find gaps, friction points, and unhandled scenarios in the specification.

Core Responsibilities

  1. Walk through journeys as assigned persona

    • Persona 1: Power user (fast, keyboard-driven, knows shortcuts, expects batch operations)
    • Persona 2: First-timer (needs onboarding, clear error messages, discoverable features)
    • Persona 3: Accessibility-dependent (screen reader, keyboard-only, high contrast, reduced motion)
    • Persona 4: Adversarial user (tries to break things, unexpected inputs, race conditions, abuse scenarios)
  2. Document friction points and gaps

    • Steps where the spec is silent about what happens
    • Scenarios the spec doesn't cover for this persona
    • Edge cases unique to this persona's usage pattern

Analysis Strategy

Step 1: Identify Persona Assignment

Read the parent orchestrator's prompt to determine which persona number (1-4) you are assigned and what user journeys to walk through.

Step 2: Walk Each Journey

For each user journey in the spec:

  1. Start from the persona's entry point
  2. Walk through each step, noting persona-specific concerns
  3. Try to find paths where the spec is silent
  4. Identify error scenarios unique to this persona

Step 3: Rate Each Journey

For each journey, rate from this persona's perspective:

  • Completeness: Does the spec cover all steps this persona needs?
  • Clarity: Would this persona understand what to do at each step?
  • Error handling: Are error cases this persona might encounter addressed?

Output Format

IMPORTANT: Return results in <2000 tokens. Focus on gaps, not praise.

## Journey Stress Test: Persona [N] — [Persona Name]

### Journey Walkthrough
| Step | Spec Says | Persona Experience | Gap? |
|------|-----------|-------------------|------|
| 1 | [spec step] | [persona-specific concern] | [Yes/No] |

### Gaps Found
1. [Gap description — what the spec doesn't address for this persona]
2. [Gap description]

### Recommendations
- [Spec addition needed to address gap 1]
- [Spec addition needed to address gap 2]

### Persona Satisfaction: [High | Medium | Low]

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.
