# /resume — read-only context loader

`/resume` rehydrates a session that lands in an in-flight worktree with no
memory of how the work got there (REQ-F2.1, D-30). It gathers the durable
context a worker needs — the kickoff brief, `tasks.md` state, the branch's
git log, the PR state, and an optional handover brief — surfaces the
working tree's uncommitted state, and asks before any work continues.

It is strictly read-only. It surfaces information and defers every decision
to the human: it never auto-stashes, auto-commits, or auto-cleans (D-30),
and as a read-only loader it never pushes or merges (REQ-F2.1). The point is
to make the situation legible, not to act on it.

This is a read-only, non-dispatching path. Outside a git repository there is
nothing to resume, so it stops with a clear message (Step 1); every other
missing prerequisite (no remote, `gh` absent, a brief that is not there yet)
degrades with a clear note and a still-useful partial load rather than a hard
halt. Both arms are graceful per REQ-K1.7: a clear message, never an opaque
failure.

## Doctrine

This skill is procedure, not doctrine. Two rule docs inform it; resolve
each via the rule-doc resolution convention
(`scripts/resolve-rule-doc.sh <doc-name>` under the resolved planwright
root, or the documented `PLANWRIGHT_ROOT` / `CLAUDE_PLUGIN_ROOT` chain):

- `spec-format` — the two-brief model (kickoff = durable contract, handover
  = optional in-worktree cache), the kickoff-brief structure, and the
  `planwright/<spec>/task-<id-or-ids>` branch convention this skill parses
  to locate the spec.
- `interaction-style` — the three disciplines and the turn/artifact
  arbitration, which govern the one attended turn this skill has: Step 8's.

Because `/resume` is a read-only loader, a doc that does not resolve is a
one-line degradation note, not a halt: fall back to reading the brief and
`tasks.md` directly and proceed (REQ-K1.7).

Doctrine manifest (machine-parseable, per `doctrine/instruction-hygiene.md`;
`run-start` loads before work begins, `point-of-use` at the named step):

Doctrine: run-start spec-format
Doctrine: point-of-use interaction-style (Step 8's turn)

## Procedure

### 1. Establish location and prerequisites

Confirm the current directory is inside a git repository and resolve its
top level. If it is not a git repo, say so plainly and stop — there is no
in-flight worktree to resume. Note (do not fail on) the absence of a remote
or of the `gh` CLI; those only narrow the PR-state step below.

### 2. Identify the in-flight unit

Read the current branch name and parse it against the convention
`planwright/<spec>/task-<id-or-ids>`. Before interpolating the parsed
`<spec>` into any path, validate it against the REQ-A1.8 spec-identifier
charset (`^[a-z0-9][a-z0-9-]*$`, max 64 chars) and refuse the reserved word
`flight`; no skill interpolates a failing identifier into a path or command
(REQ-A1.8), so a segment that fails is treated as no match. The `<spec>`
segment names the spec bundle (`specs/<spec>/`); the `<id-or-ids>` segment
names the task or bundle being executed. A flight branch
`planwright/flight/<flight-id>` is specless: say so and resolve no spec. If
the branch does not match the convention or `<spec>` fails validation (e.g.
a spec branch `planwright/<spec>/spec`, a hostile branch name, or an
unrelated branch), do not guess a task: say which branch you are on and try
to resolve `<spec>` only when it is unambiguous — a single spec bundle
under `specs/` (a direct child whose name passes the REQ-A1.8 charset; the
reserved underscore-prefixed directories `_pending/`, `_observations/`
and `_flights/` are not bundles and are skipped), or a single bundle whose
`requirements.md` carries the literal `**Status:** Active` marker and that
has a kickoff brief
(a format-version 2 bundle never stores `Active` — its header rests at
`Ready` while work is in flight — so a stored `**Status:** Ready` with a
kickoff brief counts the same way there, but only when the render reports
work in flight: a freshly signed-off, undispatched v2 bundle is not an
in-flight unit).
Both arms consider only directory names that pass REQ-A1.8 (an Active bundle
has already passed validation, so its name conforms). If that inference is
unambiguous, continue with the resolved `<spec>`. If it is not — zero
candidates (no `specs/` directory, or no bundle directory passes REQ-A1.8) or
several candidates — say so plainly and proceed with no resolved `<spec>`
(Steps 3-4 below degrade to a spec-less partial load, a clear message rather
than an opaque failure per REQ-K1.7) rather than inventing a unit.

### 3. Load the kickoff brief (the contract)

If Step 2 resolved a `<spec>`, read `specs/<spec>/kickoff-brief.md` — the
durable contract downstream work executes against. Surface the signed-off
goal restatement, the task-graph slice for the in-flight unit, and the
risk-register entries that touch it (when unsure whether an entry is
relevant, include it rather than omit it). If the brief is absent or has no
final sign-off section, note that the work predates a signed brief (or the
brief is partial) and continue with the rest of the load; do not stop. If no
`<spec>` was resolved, note that and move on — Steps 5-8 still produce a
useful spec-less partial load.

### 4. Load tasks.md state

If a `<spec>` was resolved, read `specs/<spec>/tasks.md`, keying the read
off the bundle's declared `Format-version:` (invariant-tasks D-7):

- **Format-version 1:** surface the in-flight unit's block — and when the
  branch encodes a cohesion bundle (`task-<id-or-ids>`, e.g. `task-3-4`),
  every task block the bundle covers, not just one — including each block's
  section (In progress / Awaiting input / etc.), its `Status:` and
  `Last activity:` annotations, `Done when:`, and `Dependencies:`, and note
  whether each dependency sits in `Completed`.
- **Format-version 2:** the committed file holds definitions plus
  human-authored payload only — no placement sections and no state
  annotations exist. Surface the unit's block (`Done when:`,
  `Dependencies:`) from `## Tasks`, note any reference bullet naming the
  task in `## Awaiting input`, `## Deferred`, or `## Out of scope` (a parked
  task), and read execution status — the unit's phase, each dependency's
  completion, the bundle's derived Active/Done — through the render, the
  canonical human-facing read surface (`mise run status specs/<spec>`,
  i.e. `scripts/spec-status.sh`; invariant-tasks D-6). A render failure
  degrades to reporting the definition and bullet state with a clear note.
- **Missing or unparseable `Format-version:`:** neither arm applies —
  surface it and report definitions and bullets as found, assuming
  neither version's semantics (D-7's fail-closed direction; this loader
  writes nothing regardless).

This is the canonical orchestration state record; report it as found,
without editing it. With no resolved `<spec>`, skip this step.

### 5. Load the git log

Show the recent commits on this branch (most recent first), and the
branch's relationship to its base (commits ahead / behind where that is
observable). This is what reconstructs what the prior session actually did.

### 6. Load the PR state

If a remote and the `gh` CLI are available, read the PR for this branch
(`gh pr view` on the current branch): its number, draft/ready state, title,
and review/CI status. If `gh` is absent or unauthenticated, there is no
remote, or the branch simply has no PR yet, record that no PR state is
available and proceed with a partial load: everything except the PR state is
still available (REQ-K1.6, REQ-K1.7). A branch with no PR is a normal pre-PR
state, not an error.

### 7. Load the optional handover brief and polish audit

If `<worktree>/.claude/handover.md` exists, read it and fold its in-flight
notes into the context Step 8 offers. It is an optional best-effort cache (D-3), not a
contract: its absence is normal and never an error.

`<worktree>/.claude/polish-audit.md` is the same kind of cache, left by a
standalone `/polish` run, and this skill is its named reader. If it exists,
carry it into Step 8 the way `/polish` would have: each pending sign-off and
each queued fork as one line among the question's options, the counts in the
detail, the file as the pointer. Never replay the tables into the turn. Its absence is normal and
never an error, exactly as for the brief above.

### 8. Surface the working tree and ask before proceeding

Run `git status` and surface the working tree exactly as it is: staged,
unstaged, and untracked changes. Do not stash, commit, clean, or otherwise
touch the working tree — the decision about uncommitted state belongs to
the human (D-30).

Then, before doing any further work, **ask the human how they want to
proceed**. Steps 3–7 gather; nothing they gather reaches the operator before
this turn, which is a projection of the load (`interaction-style`, the
arbitration), not the load itself:

- **The question leads**, with the decisions the load surfaced as its
  options — uncommitted changes to settle, a pending sign-off or open fork
  from the polish audit, a halt recorded against the unit — each option
  stating its own action and consequence, per the balance rules, with an
  explicit leave-it-for-now option.
- **One compact status line** follows: the unit, its derived phase, the PR
  number and draft state (or none, or unknown when Step 6 could not ask), the
  working tree as clean or a count of changed paths, and "partial load" when
  any step degraded.
- **The context elements** — unit, brief slice, task state, git log,
  PR state, handover notes, the polish audit's counts, working-tree status —
  are offered on request,
  one layer at a time, never emitted by default. A decision the operator
  must weigh is never hidden in that layer: it belongs in the question.

A follow-up the operator names in the answer gets its tracked form proposed
per `interaction-style`'s *Capture at birth*, but `/resume` stays read-only:
the session continues with that write as its first act, once the operator
confirms, and this skill never makes it. A proposal the operator declines is
not tracked. Mirror the turn into
the structured decision/transcript log as one `turn` record, sanitized like
the log's other records (D-19); where the harness provides no such log, say
the mirror was skipped, never improvising one into the repository.

When a `<spec>` was resolved, also recommend — as an **optional independent
step**, one line — that the human may run `/spec-walkthrough specs/<spec>`
themselves for an unaided, plain-language re-read of the bundle to re-orient
(REQ-F1.1, REQ-F1.2, D-11). It is a suggestion only, never a step this skill
performs, and as a read-only loader `/resume` neither runs it nor depends on
it. `/resume` ends here; continuing the work is a separate, human-initiated
step.

## Invariants

These hold at every step. The skill's one and only write is the REQ-B3.2
self-healing drift-log note (Maintenance section): recording one observation
fragment through `scripts/obs-record.sh` and committing it as its own chore
commit. That chore never touches the resumed work; every invariant below
describes the read-only guarantee over that work, and the drift-log note is
the sole carved-out exception. Step 8's `turn` record goes to a log the
harness provides, outside the repository, so it touches neither.

- **Never** modify the working tree of the resumed work: no stash, clean,
  checkout, reset, or commit of in-flight changes. `/resume` only reads it
  (REQ-F2.1); D-30 specifically forbids auto-resolving uncommitted state.
- **Never** push, create or update a PR, or merge.
- **Never** edit `tasks.md`, the brief, or any spec bundle file. The
  observations fragment store under `specs/_observations/` is the carved-out
  drift-log exception above, not a spec file. State moves belong to
  `/orchestrate` and `/execute-task`, not to a context loader.
- **Never** hard-fail opaquely on a missing prerequisite: outside a git repo,
  stop with a clear message (Step 1); for every other missing prerequisite,
  degrade with a clear note and load what is available (REQ-K1.7).

## Maintenance

After each run, compare these instructions against the doctrine and spec
they implement: REQ-F2.1 (the read-only loader contract), D-30 (surface,
do not auto-resolve), REQ-A1.8 (the spec-identifier charset gate on `<spec>`
before path use), and the `spec-format` doc's two-brief model, brief
structure, and branch convention. If the brief structure, the handover-brief
location, the identifier charset, or the branch convention have drifted from
what this skill describes, record a one-line drift observation through the
shared helper (`scripts/obs-record.sh --slug skill-drift --scope <repo>
--text 'skill-drift(resume): <what>'` — the entry text keeps the
`skill-drift(...)` prefix) and commit the fragment as its own chore commit,
per REQ-B3.2 / D-42; surface a non-zero helper exit rather than silently
dropping the observation. In repositories without `specs/`, surface the
drift to the user instead of recording it. Do not edit this skill or the
doctrine docs to resolve the drift; the accumulator's canonical reader
(`/spec-draft`) owns folding drift into spec amendments.
