Context Mode

Q: How do I know the Context Mode output is good?

The skill verifies itself against its own quality checks: `session.log` was initialised immediately on activation (not deferred); Log path shown to user is the absolute path, not relative; Output filtering is applied on the very next command run — not just announced; Filtered output format includes: command, status, summary, errors, and tail — all five fields.

Keep Claude Code sessions productive across resets with output filtering, session logging, and auto-resume. Use when starting a long or complex coding session, when previous sessions lost context mid-task, or when you need Claude to resume exactly where it left off after a reset. Produces a session.log at the project root, filtered command output that preserves context, and automatic resume of in-progress tasks after any reset.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓`session.log` was initialised immediately on activation (not deferred)

✓Log path shown to user is the absolute path, not relative

✓Output filtering is applied on the very next command run — not just announced

✓Filtered output format includes: command, status, summary, errors, and tail — all five fields

✓Session log tracks all four categories: files edited, commands run, tasks in progress, last prompt

✓Resume announcement reads the actual log contents — not a generic template

✓On resume, Claude continues the work without prompting the user for instructions

✓CLAUDE.md installation text was offered after activation

⚠️ What it refuses to do

Logging verbatim command output instead of a filtered summary (defeats the context savings)

A resume announcement from a generic template that ignores what the log actually says

Appending to "Last User Prompt" / "Last Action Taken" instead of replacing them (the log bloats)

Activating silently without offering the CLAUDE.md install, so it doesn't persist across sessions

On resume, asking the user what to do instead of continuing the in-progress task
