Capture the design decisions behind the session-handoff skill in a dedicated `.wiki/concepts/session-handoff-skill-design.md` page, indexed and logged per Karpathy LLM Wiki conventions. Covers the problem statement (cold-start fog between CC sessions), the sliding-overwrite contract for `.tasks/NEXT_SESSION.md`, the phrase whitelist + anti-pattern guards + ambiguity-asks-not-guesses rule, the substantive-commit heuristic (prefix exclude AND (body>200 OR files>3) + first-non-trivial-commit-always exception), the opt-in PostToolUse hook that replaces agent-side memory with harness-side determinism, the orient+ask read mode default, project scope guarantee, the five-section handoff content contract, secret-detect abort, staleness-7d query, mid-task capture, precedent comparison against using-tasks / MEMORY.md / log.md / Karpathy diary, and the closure record of cluster 7/7 (install / hermes-mapping / bootstrap-template-extend / posttooluse-hook / existing-projects-upgrade / test-trigger / review). Source buffer: `~/projects/.workshop/.archive/2026-05-24-session-handoff-skill.md` Round 1 design + Round 2 Q1–Q10 resolution. Also serves as the live-hook e2e smoke artifact for the deferred follow-up from `[session-handoff-posttooluse-hook]` — substantive commit (feat: prefix, body well above 200 chars) should trigger the PostToolUse `commit-detector.ps1` hook just enabled in `~/.claude/settings.json` and emit `hookSpecificOutput.additionalContext` on the next agent turn.

Entities
Concepts
- active-platform-decision.md — why
active-platformis a skill (not a memory entry); why default = Windows; how it's wired intoproject-bootstrap - bootstrap-claude-md-merge.md — project-bootstrap@1.3.0 — Step 5 upgrade path becomes idempotent merge (read → diff vs template → confirm → append missing); fixes silent gap where pre-1.2.0 projects never picked up new canonical triggers (
check across all projects,we're on Windows) - bootstrap-skill-deps-check.md — project-bootstrap@1.7.0 — Step 5.6 collapses the per-skill "detect-and-recommend" mirror shape into one generic
trigger → fulfillertable walker (skill vs plugin kind, never auto-install); subsumes the deferred[bootstrap-recommend-projects-meta]and the existingsuperpowers-only detector - bootstrap-manifest.md — record of which
project-bootstrap/setup-wiki/setup-tasksversions initialized this project's.wiki/and.tasks/layout (overwritten on re-bootstrap; history in git) - build-notes.md — why
build.ps1exists alongsidebuild.sh; PS 5.1 backslash-in-zip gotcha; how to extract a.skill - install-portability.md —
install.sh/build.shrewritten to dropmapfile(bash 4+) andfind -printf(GNU only) so stock macOS (bash 3.2 + BSD find) works - context7-setup.md — switched context7 from manual MCP entries to the official plugin; API key in
.mcp.jsonas--api-key; now also captured assetup-context7skill (one-time install/migrate flow with key discovery) - projects-meta-skills.md —
setup-projects-meta+using-projects-metaskill pair for the localprojects-meta-mcpstdio server (cross-project tasks + shared Gitea wiki); local-first rule + two-step mutation pattern - project-discipline-design.md — design for project-discipline (four cross-project rules: conventions-over-defaults, master-only, semver-bumping, ask-before-push)
- pulling-before-work-design.md — design for the pulling-before-work skill (mode-3 + skip-on-dirty)
- repo-layout.md — flat
skills/, committeddist/, bash + PowerShell scripts; install model - skill-versioning.md — why infra skills carry
version: <semver>in frontmatter and howproject-bootstraprecords them in a per-project manifest - skill-vs-plugin.md — when a bare SKILL.md is enough vs when you actually need a plugin (slash commands, hooks, sub-agents, MCP servers); concrete breakdown of
superpowers - wiki-realignment.md — fixing
project-bootstrapto create the Karpathy-canonical wiki layout - interns-design — interns-design
- compress-dedup.md —
skills/compress/deleted as a byte-identical dupe ofskills/caveman-compress/; canonical kept for README + SECURITY + caveman-toolkit branding; better Process-step wording ported across;version: 1.0.0added to caveman-compress frontmatter - active-platform-eval-design.md — spec for eval-driven tuning of
active-platform: combine the two ⚪ tasks into one workstream, 20-query cross-platform eval set (≥3 per OS + near-miss negatives),run_loop.pyautoloop in parallel with manual body sweep (WSL / BSD / ambiguity), version 1.0.0 → 1.1.0 (MINOR). Status: paused after design + pre-flight check, before eval-set authorship - interns-repo-read-design — interns-repo-read-design
- hermes-skills-rollout-design — hermes-skills-rollout-design
- tdd-criteria-design — tdd-criteria-design
- project-bootstrap-meta-isolation.md — project-bootstrap@1.11.0 — Step 1 ships meta-isolation block in
.gitignore(!.claude/,!.tasks/,!.wiki/, ...) so own greenfield/upgrade projects re-enable agent meta-paths against globalcore.excludesFilecutter. Marker-based append-only on existing files; smoke-tested with negative control - interns-grep-audit-design — interns-grep-audit-design
- session-handoff-skill-design.md — design rationale for the
session-handoffskill (sliding overwrite into.tasks/NEXT_SESSION.md, phrase whitelist + substantive-commit heuristic, optional PostToolUse hook for harness-side determinism, orient+ask default, project scope, cluster 7/7 closure)
