talk-stage2-research

Performs git archaeology, changelog analysis, and builds a verified factual timeline by cross-referencing git history with source material. REX mode only (skipped automatically in Concept mode). Use when building a REX talk and you need verified commit metrics, release timelines, and contributor data from a git repository.

Quality

Content

77%

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

The body is highly actionable with executable git commands and concrete output templates, and its workflow is clearly sequenced with a validation checklist. Its weaknesses are mild overview redundancy and a monolithic structure that bundles large templates inline rather than splitting them out.

Suggestions

Trim the redundant intro paragraph and "What This Skill Does" list, which restate the frontmatter description, to improve token efficiency.

Move the three full output-format templates into a separate reference file (e.g. references/output-templates.md) referenced one level deep, keeping SKILL.md as a leaner overview.

Tie the git commands to the numbered workflow steps so the execution order is explicit rather than implied by a separate command block.

Dimension	Reasoning	Score
Conciseness	The intro paragraph ("Builds the git proof for a REX talk. Cross-references git history, CHANGELOG, and the Stage 1 summary...") and the "What This Skill Does" list restate the description, so while most content earns its place, the overview prose could be tightened.	2 / 3
Actionability	Read-only git commands are fully executable and copy-paste ready (with the {repo_path} input placeholder), and three concrete output templates give specific, ready-to-use guidance.	3 / 3
Workflow Clarity	A six-step "What This Skill Does" sequence, a Validation Checklist, and verification rules ("Verify before asserting", "Cross-reference: flag inconsistencies") provide a clear sequence with explicit validation, appropriate for a read-only analytical skill.	3 / 3
Progressive Disclosure	The file is well-sectioned with clear navigation, but at ~140 lines it embeds three full output-format templates inline; that monolithic content could be split into reference files rather than kept entirely in SKILL.md.	2 / 3

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.

The description is specific, third-person, and clearly answers both what the skill does and when to use it, with a distinct niche that avoids conflict risk. It is a strong, concise description with no notable weaknesses.

Dimension	Reasoning	Score
Specificity	"Performs git archaeology, changelog analysis, and builds a verified factual timeline by cross-referencing git history with source material" lists multiple specific concrete actions (archaeology, changelog analysis, timeline building, cross-referencing), matching the score-3 anchor.	3 / 3
Completeness	It clearly states what it does (git archaeology, changelog analysis, verified timeline) and gives an explicit "Use when building a REX talk and you need verified commit metrics..." trigger, satisfying both what and when.	3 / 3
Trigger Term Quality	The trigger clause surfaces natural terms a user would say — "verified commit metrics, release timelines, and contributor data from a git repository" — giving good coverage rather than jargon-only phrasing.	3 / 3
Distinctiveness Conflict Risk	The REX-talk Stage 2 niche with git-archaeology/timeline triggers is highly specific and unlikely to fire for unrelated skills, matching the clear-niche anchor.	3 / 3
