Project with your last 30 posts as voice anchor. You write the angles (you live them), Claude drafts.
LinkedIn (for yourself)
Drop the multi-client agency tooling. For your own account you don't need Granola interviews or Taplio's viral search. Claude with your own voice library, Typefully to stage and ship, that's it.

Usage and Cost Analytics API launched in beta to track token consumption and costs
Anthropic released the Usage and Cost Analytics API in beta, enabling organizations to monitor token usage and costs across Claude API consumption with filtering and grouping by dimensions like model, workspace, and API key. The API provides /v1/organizations/analytics/usage and /v1/organizations/analytics/cost endpoints. Legacy usage reporting endpoints remain supported.
Messages API and Token Counting API maximum request size increased to 128 MB
The maximum request size for the Messages API and Token Counting API doubled from 32 MB to 128 MB on the first-party Claude API, allowing developers to process significantly larger payloads in single requests. This change takes effect immediately and applies to both APIs.

When something happens at work, jot a 1-line angle. You don't need a 30-min interview if you live the work.

Sunday session: feed Claude 5 angles + your voice library, get 5 drafts.
Prompt · Batch draft from your own anglesWrite 5 LinkedIn posts in my voice. Voice library (my last 20 posts): """ {{paste 20 posts}} """ This week's angles (one post per angle): 1. {{angle 1}} 2. {{angle 2}} 3. {{angle 3}} 4. {{angle 4}} 5. {{angle 5}} Constraints per post: - Hook in line 1, no warm-up - 5 to 8 short paragraphs, blank line between - One concrete number, name, or example - No emoji unless my voice library uses them - End on a sharp statement, not a question Output 5 posts separated by "---". - 3Stage in TypefullyTypefully
Paste, schedule across the week. Typefully cross-posts to X if you want a thread version.
From posting twice a month to 3x/week. Reach went from ~600 impressions/post to ~3.2k impressions/post over 6 weeks. 11 inbound messages per month from posts alone.
Without an interview to ground in, drafts drift to generic LinkedIn-speak fast. Keep refreshing the voice library every 4 weeks.
Daily posting without batching burns out within a month. Sunday batching (5 posts in 90 min) is the only thing that holds.
