Quality

Content

72%Weight 40%Scale 1-5

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

Highly actionable and well-structured tmux guidance with executable, idempotent patterns and clear isolation rules. The main weakness is repetition of the same SESSION-derivation and guard boilerplate across many sections, which inflates token cost without adding new information.

Suggestions

Factor the repeated `SESSION=$(basename $(git rev-parse --show-toplevel 2>/dev/null) || basename $PWD)` line into a single defined snippet referenced once, instead of restating it in every code block.

Consolidate the has-session / list-windows guard pattern into one reusable template rather than duplicating it across the Single Process, Adding a Window, and Multiple Processes sections.

Add an explicit validation checkpoint after lifecycle actions (e.g., confirm `has-session` returns false after `kill-session`, or verify the ready poll loop reports failure when the server never starts) to strengthen the feedback loop for destructive operations.

DimensionReasoningScore

Conciseness

The body repeats the same SESSION derivation line verbatim across roughly a dozen code blocks and restates the has-session check pattern many times; while accurate, this padding could be factored into a single shared snippet, leaving it mostly efficient but noticeably repetitive.

3 / 5

Actionability

Every section provides copy-paste ready, executable bash with concrete commands (has-session, send-keys, capture-pane, kill-session) covering the common cases including wrong-vs-correct examples, matching the fully-executable top anchor.

5 / 5

Workflow Clarity

Sequences are clear with idempotent has-session / list-windows guards acting as checkpoints and a dedicated error-checking/ready-poll pattern, but the process lifecycle lacks an explicit validate-after-action feedback loop, leaving minor validation gaps relative to the top anchor.

4 / 5

Progressive Disclosure

Content is well-organized into clearly labeled sections (Reuse Rules, Naming, Starting, Monitoring, Lifecycle) appropriate for a single self-contained file with no bundle files present; the only gap is the repeated boilerplate that could be consolidated, keeping it just below the top anchor.

Description

83%Weight 40%Scale 1-5

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, well-structured description that clearly states both capability and trigger conditions in third person. Minor broadness in 'any process expected to outlive the conversation' slightly tempers specificity and distinctiveness.

DimensionReasoningScore

Specificity

The description names the domain (long-lived processes in tmux) and lists several concrete actions (starting dev servers, watchers, tilt), though 'any process expected to outlive the conversation' is somewhat generic compared to the anchor listing multiple concrete actions.

4 / 5

Completeness

It explicitly answers both what ('Patterns for running long-lived processes in tmux') and when ('Use when starting dev servers, watchers, tilt, or any process expected to outlive the conversation') with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

It includes natural trigger terms users would say ('dev servers', 'watchers', 'tilt') with good coverage, but misses common synonyms like 'background process' or 'long-running' phrasing a user might naturally use.

4 / 5

Distinctiveness Conflict Risk

The tmux niche is clearly distinct and trigger-specific, but 'any process expected to outlive the conversation' is broad enough to create minor overlap risk with general background-process or bash skills.
