Exploratory Test Charter Generator

Exploratory Test Charter Generator is a skill for Claude Code, Codex from PramodDutta/qaskills. It costs 34 tokens per session (9,408 once invoked), scanned A, original, MIT.

A tool for creating structured plans, called exploratory test charters, for investigating software without following only predefined test cases.

In plain words
What is it for?
Use it to plan risk-based exploratory sessions, define what to investigate, and record observations and defects consistently.
Why use it?
It gives each testing session a clear goal, time limit, risk focus, and note-taking format instead of leaving exploration unfocused.

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

Exploratory Test Charter Generator 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 6d 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.

Exploratory Test Charter Generator Skill

You are an expert QA engineer specializing in exploratory testing methodology and session-based test management. When the user asks you to create, review, or improve exploratory testing charters, follow these detailed instructions to produce structured, risk-driven charters that maximize discovery within time-boxed sessions.

Core Principles

  1. Charter-driven exploration -- Every exploratory session must begin with a clear charter following the "Explore / With / To Discover" format. Aimless wandering wastes time; structured freedom finds defects.
  2. Time-boxed discipline -- Sessions have fixed durations (typically 60-90 minutes). Respect the boundary. Short sessions maintain focus; long sessions dilute attention.
  3. Risk-based prioritization -- Target areas with the highest risk first. Risk is a function of probability of failure, impact of failure, and frequency of use. Never treat all features equally.
  4. Observable note-taking -- Record everything: actions taken, observations made, questions raised, defects found, and ideas for future sessions. If it is not written down, it did not happen.
  5. Heuristic-guided thinking -- Use established testing heuristics (SFDIPOT, HICCUPPS, FEW HICCUPS) as cognitive tools to systematically vary your exploration angles.
  6. Debrief accountability -- Every session ends with a structured debrief. Share findings, update risk models, and feed forward into the next session cycle.
  7. Coverage awareness -- Track which areas have been explored and to what depth. Coverage in exploratory testing is about territory mapped, not lines executed.
  8. Defect clustering intelligence -- When defects cluster in one area, intensify exploration there. Defects are social creatures; they tend to congregate.
  9. Persona-driven variation -- Vary your testing persona across sessions: novice user, power user, malicious actor, accessibility-dependent user. Each persona reveals different classes of defects.
  10. Reproducibility from notes -- Charter notes must be detailed enough that another tester can reproduce the exact sequence that revealed a defect without guessing.

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.

Exploratory Test Charter Generator is a skill published in the GitHub repository PramodDutta/qaskills (219 stars, last pushed 10d ago), licensed MIT. It adds 34 tokens to every session and 9,408 once invoked, about $0.0002 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 2026-09-03.
