customer-win-back-sequencer

For churned accounts, research what has changed since they left — new funding, team growth, competitor dissatisfaction, product updates that address their pain — then assess re-engagement potential and generate a personalized win-back email sequence with timing recommendations. Chains web research and LinkedIn monitoring with email sequence generation.

Quality

Content

76%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.

The body is highly actionable with concrete search queries, a scoring rubric, and complete templates, but the batch workflow lacks explicit validation checkpoints, and the long email/output blocks could be split into reference files for cleaner progressive disclosure.

Suggestions

Add explicit validation steps in the batch workflow — e.g., after Phase 1 research, verify each account's contact email is still valid and confirm at least one change signal before scoring; after Phase 3, confirm sequences are populated for every High Priority account before saving.

Move the full email templates and output-format spec into reference files (e.g., references/email-templates.md and references/output-format.md) and link to them from the body to improve progressive disclosure.

Tighten the opening prose and remove parenthetical restatements to reduce token overhead.

DimensionReasoningScore

Conciseness

Dense and actionable with minimal padding, though the opening prose and several parenthetical asides ('Too recent = too soon. Too old = too stale.') could be trimmed.

4 / 5

Actionability

Provides copy-paste-ready search query templates, a concrete scoring formula with numeric anchors, full email templates, and a complete output-format spec covering common cases.

5 / 5

Workflow Clarity

Phases 0–4 are clearly sequenced, but this batch operation across multiple accounts lacks explicit validation/verification checkpoints (e.g., confirm research findings, verify contact emails before sequencing), capping it at 3.

3 / 5

Progressive Disclosure

No bundle files exist; the single document is well-organized with clear section headers, though the lengthy email templates and output format could arguably live in separate reference files.

Description

75%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.

The description is specific and occupies a distinct niche, but it omits an explicit 'Use when…' trigger clause, which caps its completeness. Adding natural trigger phrasing would raise the score.

Suggestions

Add an explicit 'Use when…' clause with concrete triggers (e.g., 'Use when re-engaging churned accounts, building a win-back campaign, or scanning a churn list for re-engagement opportunities').

Include common synonyms and file/context cues like 'churned customers', 'reactivation', 'win-back campaign', and 'churn list' to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — researching funding/team growth/competitor dissatisfaction/product updates, assessing re-engagement potential, and generating a personalized win-back email sequence with timing.

5 / 5

Completeness

Clearly states what the skill does, but has no explicit 'Use when…' trigger clause, so the 'when' is only weakly implied; the missing trigger guidance caps completeness at 3.

3 / 5

Trigger Term Quality

Includes natural terms like 'churned accounts', 'win-back email sequence', and 're-engagement potential', but lacks common synonyms and variations a user might say.

4 / 5

Distinctiveness Conflict Risk

Targets a clear niche — churned-account win-back via change-signal research — with triggers unlikely to fire for unrelated skills.
