chronology

Build or update a chronology from declared document sources and uploads — dated events extracted, de-duped, and tagged by significance per the matter theory. Use when the user asks to build a chronology or timeline from a production or matter file, says "chron from the production" or "what happened when", or needs a working, statement-of-facts, or witness-specific timeline.

Quality

Content

77%Weight 40%Scale 1-3

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

A thorough, highly actionable legal workflow with strong sequencing and validation gates, but it is verbose in places and ships as a single large file that could offload detail to references.

Suggestions

Trim motivational/rationale prose (e.g., the "Facts happen in order…" intro and "Why a gate and not just a warning" block) to the essential rule, keeping the gate behavior without the justification paragraph.

Move the full output-format template and the marker-discipline / privilege-doctrine detail into reference files (e.g. references/output-template.md, references/privilege.md) and link them one level deep from SKILL.md to improve progressive disclosure.

Consolidate the repeated provenance-tagging rules (Step 2 "Source attribution", "Tagging reaches every section…") into a single canonical list to reduce redundancy.

DimensionReasoningScore

Conciseness

The body is mostly efficient and domain-specific, but motivational framing ("Facts happen in order… garbage-in, garbage-out") and rationale blocks ("Why a gate and not just a warning…") pad the prose and could be tightened.

2 / 3

Actionability

Concrete file paths, per-source extraction formats, enumerated tag values (🔴/🟡/⚪, priv: ok/flag/review), and a full copy-paste output template give fully executable instruction-only guidance.

3 / 3

Workflow Clarity

Steps 0–6 are clearly sequenced with explicit validation gates (privilege gate, conflicts gate), stop-and-ask feedback loops, SME-VERIFY flags, and a confirm-before-finalize checkpoint for this batch extraction operation.

3 / 3

Progressive Disclosure

No bundle files exist and the ~280-line SKILL.md is monolithic, with the output template, privilege doctrine, and marker discipline kept inline rather than split into one-level-deep reference files.

Description

100%Weight 40%Scale 1-3

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 states concrete capabilities and provides explicit, natural-language triggers covering multiple invocation scenarios. It clearly distinguishes the skill from neighboring ones.

DimensionReasoningScore

Specificity

"Build or update a chronology from declared document sources and uploads — dated events extracted, de-duped, and tagged by significance" names several concrete actions (extract, de-dupe, tag) in third-person imperative voice.

3 / 3

Completeness

It explicitly answers what (build/update a chronology from sources with extraction, de-dupe, tagging) and when via an explicit "Use when…" trigger clause covering several scenarios.

3 / 3

Trigger Term Quality

Natural phrasing a user would say is well covered: "build a chronology or timeline", "chron from the production", and "what happened when".

3 / 3

Distinctiveness Conflict Risk

The litigation chronology niche is clearly scoped with distinct triggers (production/matter files, SoF/witness timelines) unlikely to fire for unrelated skills.
