cold-outbound-optimizer

Design, analyze, and optimize cold outbound email campaigns for Instantly. Handles end-to-end ICP definition, expert panel scoring (recursive to 90+), sequence copywriting, infrastructure audit, capacity planning, and implementation docs. Use when asked to build cold outbound sequences, optimize cold email, analyze outbound campaigns, build sales sequences, build Instantly sequences, create cold outbound strategies, or design email campaigns. Supports both "start from scratch" and "optimize existing" modes.

Quality

Content

85%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.

A well-organized, mostly lean skill body with a clearly sequenced multi-phase workflow, explicit validation/feedback loops, and clean one-level-deep progressive disclosure verified against real bundle files. The only trim opportunities are the telemetry preamble and a reference table that restates inline citations.

Suggestions

Consider moving the telemetry/version-check preamble into a short reference or collapsing it to a single line, since it is incidental to the core outbound workflow and consumes tokens on every load.

Add one short inline example of a scored email step (subject + first line + CTA) so the core copywriting craft is actionable without forcing a jump to references/copy-rules.md.

Dimension	Reasoning	Score
Conciseness	The body is largely lean and assumes Claude's competence without explaining basic concepts, but the telemetry preamble (version check, telemetry_init, privacy note) and the end Reference Files table restate inline-given information and could be trimmed.	4 / 5
Actionability	Provides concrete executable commands ('python3 scripts/instantly-audit.py --api-key <KEY>'), a copy-paste capacity formula, and a metrics table, but the core copywriting craft has no inline example and is delegated to reference files — mostly executable with minor gaps.	4 / 5
Workflow Clarity	A clearly sequenced multi-phase process (Startup → Phase 1 Discovery → Phase 2 Scoring → Phase 3 Deliverables) with explicit validation checkpoints: warmup-readiness flags, the 'iterate until 90+' feedback loop, and a Human Review Gate requiring explicit approval before API writes.	5 / 5
Progressive Disclosure	Clear overview with well-signaled, one-level-deep references; every inline reference (icp-template.md, expert-panel.md, instantly-rules.md, copy-rules.md, and the five scripts) resolves to a real bundle file, and a Reference Files table maps each file to its purpose for easy navigation.	5 / 5

Description

96%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 concretely lists capabilities and provides explicit, natural trigger phrases covering both modes of operation. Only minor overlap risk from a few broadly-worded triggers keeps distinctiveness just below the top anchor.

Suggestions

Tighten the broadest triggers ('design email campaigns', 'build sales sequences') by scoping them to cold/outbound context (e.g., 'build cold sales sequences') to reduce overlap with general email-marketing skills.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'ICP definition, expert panel scoring (recursive to 90+), sequence copywriting, infrastructure audit, capacity planning, and implementation docs' — giving comprehensive coverage of the skill's capabilities.	5 / 5
Completeness	Explicitly answers both 'what' (Design, analyze, and optimize... Handles end-to-end...) and 'when' (Use when asked to build...) with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	Natural user phrasing with synonym coverage — 'build cold outbound sequences, optimize cold email, analyze outbound campaigns, build sales sequences, build Instantly sequences, create cold outbound strategies, or design email campaigns' — maps well to what a user would actually say.	5 / 5
Distinctiveness Conflict Risk	Mostly distinct niche (cold outbound for Instantly), but broader triggers like 'design email campaigns' and 'build sales sequences' carry minor overlap risk with general email-marketing skills, placing it just below the top anchor.	4 / 5
	Total	19 / 20 Passed
