# Changelog

All notable changes to graceful-handoff are documented here.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

## [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](https://github.com/anthropics/claude-code/issues/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
