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.

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

This is a well-structured, highly actionable skill with executable git commands, complete output templates, and clear validation steps. Its main weakness is moderate verbosity—the inline output format templates are thorough but lengthy, and some introductory sections are redundant. The workflow is clear with good safety constraints and cross-referencing requirements.

Suggestions

Remove or consolidate the 'When to Use This Skill' and 'What This Skill Does' sections into the intro paragraph to reduce redundancy

Consider extracting the three detailed output format templates into a separate reference file (e.g., FORMATS.md) and linking to it, keeping SKILL.md as a concise overview

Dimension	Reasoning	Score
Conciseness	The skill is reasonably efficient but includes some unnecessary sections like 'When to Use This Skill' and 'What This Skill Does' that largely repeat the intro and description. The output format templates are extensive and could arguably be more concise, though they do serve as concrete specifications. The 'Tips' section adds marginal value.	2 / 3
Actionability	Provides fully executable git commands with proper parameterization, complete output file templates with exact markdown structure, clear input/output file naming conventions, and a validation checklist. Everything is copy-paste ready and specific.	3 / 3
Workflow Clarity	The workflow is clearly sequenced (read summary → git archaeology → changelog analysis → cross-reference → build timeline → write 3 files). Includes explicit validation checklist with safety constraints (read-only only), cross-reference verification steps, and anti-patterns that serve as error prevention. The 'Verify before asserting' and conflict-flagging rules provide feedback loops.	3 / 3
Progressive Disclosure	The skill references related stages via relative links which is good navigation. However, the three complete output format templates inline make the file quite long (~180 lines of templates). These could be split into a separate FORMATS.md or similar reference file, keeping SKILL.md as a leaner overview. No bundle files exist to offload this content to.	2 / 3

Description

85%

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

This is a well-crafted description that clearly defines both what the skill does and when to use it, with a distinct niche around REX talk preparation via git history analysis. The specificity of actions and the explicit 'Use when...' clause are strong. The main weakness is that trigger terms are somewhat domain-specific and may not cover all natural phrasings a user might employ when needing this functionality.

Suggestions

Add more natural trigger term variations such as 'git log', 'commit history', 'version history', or 'repository analysis' to improve keyword coverage for users who may not use the term 'git archaeology'.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'git archaeology', 'changelog analysis', 'builds a verified factual timeline', 'cross-referencing git history with source material', 'verified commit metrics, release timelines, and contributor data'.	3 / 3
Completeness	Clearly answers both what ('performs git archaeology, changelog analysis, builds verified factual timeline by cross-referencing git history') and when ('Use when building a REX talk and you need verified commit metrics, release timelines, and contributor data from a git repository').	3 / 3
Trigger Term Quality	Includes some relevant keywords like 'git', 'changelog', 'commit metrics', 'release timelines', 'contributor data', and 'git repository', but the terms are somewhat specialized (e.g., 'git archaeology', 'REX mode') and may not match common user phrasing. Missing natural variations like 'git log', 'git history', 'commit history'.	2 / 3
Distinctiveness Conflict Risk	Highly distinctive with a clear niche: it's specifically for REX talk preparation using git history analysis. The mention of 'REX mode only' and the specific combination of git archaeology + timeline building makes it very unlikely to conflict with other skills.	3 / 3
