If Claude Code keeps tripping over 'File has been modified since read it' partway through a long session, the cause usually narrows down to three settings. Here is what actually worked in my own setup.
Notes from Seven Months of Running a Four-Site Auto-Publishing Pipeline with Claude Code and GitHub Actions
Lessons from running Claude Code scheduled tasks to auto-publish 16 articles a day across four Lab sites, including the Helpful Content System index collapse that forced a redesign of the quality gate, with the full Python gate code, token management, and rollback procedure.
Three State-Passing Patterns for Claude Code Subagents — Lessons from 4 Months of Automated Blog Pipelines
JSON files, environment variables, and context bundles — three ways to hand state between Claude Code subagents, compared with four months of production data and clear guidance on when to pick each.
Putting an Autonomous Librarian on Top of Claude Code × Obsidian — Operating Notes From Running Four Sites Through a Three-Layer Knowledge OS

The article covers the three-layer storage, ingest/compile Skills, Dataview monitoring, and a weekly audit job — all sized for real production use.
Five Filters I Use Before Wiring a Claude Code Skill Into My Daily Workflow
Public Claude Code Skills keep multiplying. As an indie developer running a few tech blogs through Claude Code, I share the filters that decide which Skills stay in my daily workflow — and which ones I quietly remove after a few days.
Recovering from Claude Code's 'Tool result could not be submitted'
What 'Tool result could not be submitted' really means in Claude Code, and the practical recovery steps I rely on after years of running indie apps with 50M+ downloads through it.
When Claude Code's Sequential Edits Cascade into Failure — Fixing 'old_string not found' and 'not unique' on the Same File
Run several Edits against the same file in one turn and the second or third one suddenly fails with 'not found' or 'not unique'. The cause is order-dependence inside a single context snapshot, and a Read + scoped patches usually rescue it.

Retiring Dormant SDKs with Claude Code — A 12-Year Indie Developer's Pipeline for Safely Auditing Inactive Dependencies
Twelve years of indie iOS/Android development leaves a quiet sediment of SDKs that nobody calls anymore — but the dependencies remain. Here is the Claude Code pipeline I built to audit and safely retire them across four wallpaper apps, with the actual code and four weeks of operational metrics.
