exploratory-testing SKILL.md skillA

exploratory-testing from qa-aman/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add qa-aman/claude-skills/exploratory-testing@git:20260303.9d46210

Pins git:20260303.9d46210 in mdr.lock. Pin the fingerprint instead.

Run structured exploratory testing sessions using test charters, timeboxing, and heuristics. Use when user says "exploratory testing", "charter-based testing", "explore the app", "unscripted testing", "session-based testing", "find unknown bugs", or needs to test an area without predefined scripts - even if they don't explicitly say "exploratory".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Overview

Exploratory testing is simultaneous learning, test design, and execution. Based on "Exploratory
Software Testing" by Elisabeth Hendrickson and "Explore It!" (same author), this approach replaces
rigid test scripts with structured investigation using charters, timeboxes, and heuristics.

The core insight: scripted tests only find bugs you already imagined. Exploratory testing finds the
bugs you didn't anticipate - the ones that emerge from real usage patterns, unexpected interactions,
and system behaviors that scripted coverage can never reach.

## Workflow

### Step 1: Write a test charter

A charter defines the scope and mission of one exploratory session. Format:

```
Explore [area or feature]
Using [technique, tool, or approach]
To discover [information or risk type]
```

Examples:
- "Explore the checkout flow using rapid input variations to discover validation gaps."
- "Explore file upload using boundary conditions (0 bytes, max size, wrong MIME type) to discover error handling failures."
- "Explore user permissions using role-switching sequences to discover authorization gaps."

One charter = one session. Keep scope narrow enough to complete in 60-90 minutes.

How to install

The exact contents, by fingerprint

mdr add qa-aman/claude-skills/exploratory-testing@sha256:7175dc9923f73eef

The line at the top of this page pins the label git:20260303.9d46210, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
