[2.1.0] - 2026-05-01

Fixed

• Modell-bevisst kontekstvindu i Stop hook (stop-context-monitor.mjs). Tidligere fallback antok 200K-vindu. På Opus 4.7-sesjoner (faktisk 1M-vindu) kunne auto-handoff fyre 5–7x for tidlig — estimert 70% når reell bruk var ~14%. Erstatter windowSize = payload?.context_window?.context_window_size || 200_000 med en 4-stegs resolution-kjede (resolveContextSource()):
  1. payload.context_window.used_percentage (autoritativ, modell-agnostisk — kilde: direct)
  2. payload.context_window.context_window_size + transcript-estimat (kilde: payload-size)
  3. MODEL_WINDOWS[payload.model.id] + estimat (Opus 4.7=1M, Sonnet 4.6=200K, Haiku=200K — kilde: model-map)
  4. FALLBACK_WINDOW = 1_000_000 + estimat (oppdatert 2026-default — kilde: default-1m)

Changed

• additionalContext-meldinger fra Stop hook inkluderer nå [kilde: <source>] for innsyn i hvilken resolution-path som ble brukt (direct/payload-size/model-map/default-1m).
• Inline-kommentar (linje 14–22) og README/CLAUDE.md-seksjoner om auto-trigger-mekanikk oppdatert til å beskrive ny kjede.

Tests

• 6 nye tester i tests/hooks/stop-context-monitor.test.mjs dekker hver path: used_percentage foretrukket, used_percentage trigger med tom transcript, model-map for Opus 4.7 (1M) og Haiku (200K), default 1M-fallback med tomt payload, og null used_percentage faller gjennom til size-pathen. Total: 56 tester (50 + 6).

Open

• Stop-hook payload-schema er ikke offisielt dokumentert. Det er ikke bekreftet at Stop-payload faktisk inneholder used_percentage eller model.id (statusLine-payload gjør). Hvis ingen av feltene leveres, faller resolveren til default-1m. Smoke-test ved første Opus 4.7-sesjon vil avgjøre hvilken kilde som blir primær.

[2.0.0] - 2026-05-01

BREAKING

• Hard cut from commands/ to skills/. The plugin now ships a single SKILL.md at skills/graceful-handoff/SKILL.md with disable-model-invocation: true and model: claude-sonnet-4-6. The legacy commands/graceful-handoff.md is deleted. User-invocation /graceful-handoff works as before.
• Architecture rewrite. The 6-phase prose workflow is replaced by a deterministic Node script scripts/handoff-pipeline.mjs that returns structured JSON. SKILL.md is now a thin orchestration wrapper. Tests run directly against the pipeline without LLM involvement.
• Removed auto_discover: true from plugin.json (not in documented schema; silently ignored anyway per research/05).

Added

• Auto-trigger via Stop hook (hooks/scripts/stop-context-monitor.mjs). Estimates context usage from transcript size; at estimated ≥70%, auto-writes the artifact and creates a commit. Push remains user-triggered (separates reversible from irreversible). Lock file at <transcript_dir>/.handoff-lock-<session_id> prevents repeat firing within a session.
• Context hint via statusLine (hooks/scripts/statusline-monitor.mjs). Reads context_window.used_percentage from payload; prints a hint at 60% and an urgent reminder at 70%. Display-only — never runs git (unsafe per research/03).
• Auto-load via SessionStart hook (hooks/scripts/session-start-load-handoff.mjs). On source: resume or source: compact, finds NEXT-SESSION-*.local.md (cwd + 3 levels up), injects content via additionalContext, archives the file (*.archived.local.md) to prevent stale-load.
• Commit-message confirmation gate: pipeline prints message to stderr, reads y/n from stdin (interactive). --auto flag bypasses for hook-driven invocations.
• New flags: --no-push (commit but don't push), --auto (non-interactive auto-Y), --non-interactive.
• Pipeline robustness: detached HEAD detection, no-upstream detection, idempotency check (60s cooldown on clean tree), pre-commit hook respect.
• 36 unit tests across 5 test files (skill-structure, pipeline, statusline-monitor, stop-context-monitor, session-start-load-handoff).

Changed

• Pipeline staging discipline (CRITICAL). Pipeline now stages ONLY the handoff artifact (and REMEMBER.md/TODO.md if present). Previously used git add -A which scoops up unrelated work-in-progress. The new behavior is enforced by a regression test.
• allowed-tools is now Bash sub-scoped (Bash(git:*) Bash(node:*) Bash(jq:*) ...) instead of an open Bash. Note: per research/02, this is pre-approval (not restriction) — to actually block tools, project-level deny rules are needed.
• Plugin model is pinned to claude-sonnet-4-6 (was: inherit from session). Frees Opus 4.7 budget for the next session that the user is actually entering.

Known limitations

• statusLine placement in hooks/hooks.json is an open assumption (research/03 confirmed statusLine config exists, but exact placement vs settings.json is unverified). Smoke-test required.
• Token estimation in Stop hook uses chars/3.5 heuristic — may drift ±10% from Claude's internal counting. The 70% threshold is conservatively set.
• disable-model-invocation: true has open issue #26251; manual smoke-test recommended before relying on it.
• Auto-execute does not push: irreversible operations remain user-triggered.

Migration from v1.0.0

There is no automatic migration. v2.0.0 is a breaking change.

1. Reinstall the plugin to pick up skills/ and remove commands/.
2. The /graceful-handoff slash command works identically from the user's perspective.
3. The new auto-trigger features activate automatically when the plugin's hooks are loaded.

[1.0.0] - 2026-04-19

Added

• Initial release with single command /graceful-handoff
• 6-fase deklarativ workflow: detect → classify → write artifact → update REMEMBER/TODO → commit+push → print copy-paste-prompt
• Tre handoff-typer: multi-sesjon (ultraplan-prosjekt), plugin-arbeid (marketplace-plugin), enkelt-oppgave (fallback)
• Default filnavn NEXT-SESSION-PROMPT.local.md; slug-override via første posisjons-argument
• Flag: --no-commit (skip git), --dry-run (ingen skriving, ingen git-ops)
• Auto-generert Conventional Commits-melding fra git diff --stat
• Respekterer pre-commit hooks (secrets, pathguard) — bypasser aldri
• Tidsbudsjett < 60 sekunder; ingen Agent-delegering, ingen WebSearch
• 7-seksjons-template for NEXT-SESSION-artefakt (matcher eksisterende konvensjon i llm-security/config-audit)

Notes

• Auto-discover plugin — marketplace.json-oppføring ikke nødvendig
• MIT-lisens
