testland/session-based-test-management-reference

Pure-reference catalog of Session-Based Test Management (SBTM) - the Bachs' framework for running exploratory testing as time-boxed sessions: the session (60-90 min), the charter (Explore X with Y to discover Z), the session-sheet structure, the TBS metrics, the cross-session dashboard, and the PROOF debrief. Use when authoring exploratory-testing charters, reviewing session sheets, or setting up time-boxed test sessions. Distinct from manual-test-debrief (the PROOF debrief template), exploratory-tours-reference (the session themes), and the heuristic catalog hiccupps-f-heuristic.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured reference body with actionable templates, a sequenced workflow containing an explicit validation checkpoint, and clean one-level-deep progressive disclosure. The main weakness is redundancy: the session time-box and TBS ranges are repeated several times across sections.

Suggestions

State the 60-90 min / ~2-hour session cap once (e.g. in 'The unit: a session') and reference it from the Overview and How-to-use steps rather than restating it three extra times.

Consolidate the TBS healthy ranges into a single location and link outward, instead of repeating them in How-to-use step 4, 'The session sheet and metrics', and the reference file.

Merge overlapping rows between the 'Common confusions' and 'Anti-patterns' tables (e.g. session length, multi-charter sessions) to remove duplicated guidance.

DimensionReasoningScore

Conciseness

The 60-90 min / ~2-hour cap is restated four times (Overview, How-to step 2, 'The unit: a session', and the Bach quote) and the TBS healthy ranges are repeated three times, so the body is mostly efficient but could be tightened. It is not a level 3 because redundant restating competes with the context budget.

2 / 3

Actionability

Provides concrete, specific guidance: the 'Explore <area> with <tools> to discover <information>' charter template with a worked example, exact TBS percentages (T 60-80%, B 10-20%, S 10-15%), and the PROOF letter definitions. As an instruction-only reference the absence of code is not penalized since the guidance is actionable.

3 / 3

Workflow Clarity

The numbered 6-step 'How to use' is clearly sequenced and includes an explicit validation/feedback checkpoint in step 4 ('if T < 50%, stop and fix the cause... then re-run the session before aggregating'), matching the clear-sequence-with-validation anchor.

3 / 3

Progressive Disclosure

The body is a well-organized overview that points to a single, clearly signaled, one-level-deep reference (references/session-sheet-and-metrics.md, which exists and is real) via markdown links, with content appropriately split between the overview and the reference.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that names concrete framework components, gives an explicit 'Use when' trigger, and explicitly distinguishes the skill from its siblings. It cleanly satisfies the what/when/distinctiveness requirements without padding.

DimensionReasoningScore

Specificity

Enumerates multiple concrete framework components ('the session (60-90 min), the charter (Explore X with Y to discover Z), the session-sheet structure, the TBS metrics, the cross-session dashboard, and the PROOF debrief') and concrete Use-when actions ('authoring exploratory-testing charters, reviewing session sheets, or setting up time-boxed test sessions'), rather than vague language.

3 / 3

Completeness

Explicitly answers both 'what' ('Pure-reference catalog of Session-Based Test Management (SBTM)...') and 'when' via an explicit 'Use when authoring exploratory-testing charters, reviewing session sheets, or setting up time-boxed test sessions' trigger clause.

3 / 3

Trigger Term Quality

Covers natural terms a test lead would actually say — 'Session-Based Test Management (SBTM)', 'exploratory-testing charters', 'session sheets', and 'time-boxed test sessions' — giving good coverage of common phrasings.

3 / 3

Distinctiveness Conflict Risk

States a clear niche and explicitly differentiates siblings ('Distinct from manual-test-debrief..., exploratory-tours-reference..., and the heuristic catalog hiccupps-f-heuristic'), making mis-triggering unlikely. Voice is third-person, so no specificity penalty applies.
