Outputs a severity-scored report with a recommended action per cluster (merge, differentiate, canonical, noindex, or no action). Use when the user says "cannibalization", "keyword overlap", "competing pages". Not a site audit (blog-audit) or cluster planning (blog-cluster); it changes no files or redirects.WritingNo warnings★ 2.6K↓ —

estimating-and-contingency
cbrock84/headcount
OtherUpdated Oct 18, 2026
From the author
Produces a cost or effort estimate someone can defend — decomposing the work, choosing between analogous, parametric and bottom-up methods, documenting the basis and its assumptions, expressing confidence as a range, and sizing contingency and management reserve separately. Use this to build an estimate, challenge one you have been handed, work out why estimates keep coming in low, or decide how much reserve a portfolio actually needs.
