Handoff Receiver

Handoff Receiver

Use this skill when you are the new skill/agent receiving work from a previous session handoff file.

Goal: continue delivery with minimal drift, no scope expansion, and clear state recovery.

Step 1: Locate the active handoff and index

1. Prefer .trellis/handoffs/CURRENT when present.
2. Otherwise use docs/handoffs/CURRENT when present.
3. Otherwise use CURRENT in project root.
4. Read the matching INDEX.md in the same handoff directory.
5. Only if no pointer exists, fall back to the latest legacy handoff file.

if [ -f ".trellis/handoffs/CURRENT" ]; then
  cat .trellis/handoffs/CURRENT
  echo ".trellis/handoffs/INDEX.md"
elif [ -f "docs/handoffs/CURRENT" ]; then
  cat docs/handoffs/CURRENT
  echo "docs/handoffs/INDEX.md"
elif [ -f "CURRENT" ]; then
  cat CURRENT
  echo "INDEX.md"
else
  [ -f handoff.md ] && echo "handoff.md"
fi

If no handoff is found, stop and ask one minimal question requesting the handoff path.

Step 1.5: Read the compact index before opening any other handoff

Read INDEX.md and classify streams from the table only.

• status: in_progress or status: open and matches CURRENT → active. Proceed.
• status: in_progress and does not match CURRENT → conflict. Ask the user which stream is authoritative.
• status: paused → parallel stream. Surface it in takeover output, but do not execute it.
• status: done or status: superseded → archive. Skip.
• any handoff row with status: orphan → open only that file's Goal and Next Steps, then ask the user whether to mark it paused, merge it, supersede it, or leave it as-is.
• if CURRENT points to a handoff missing from INDEX.md, treat that as an index drift bug and ask one focused question before continuing.

Do not scan the handoff directory in the normal path. Directory scans are reserved for index repair only.

After locating the active handoff, mark it before execution:

• status: in_progress
• taken_over_at: <now>
• taken_over_by: handoff-receiver
• updated_at: <now>

Step 2: Read only decision-critical sections first

Read these sections in this order:

1. Goal
2. Current State
3. Next Steps
4. Decisions Made
5. Context for the Next Session

Capture:

• in-scope objective
• current completion status
• first actionable next step
• explicit constraints and trade-offs

Step 3: Reconcile handoff vs repository reality

Run objective checks before touching code:

git rev-parse --abbrev-ref HEAD
git status --short
git diff --stat HEAD
git log --oneline -10

Then compare with Files Changed and Commands Run in the handoff.

If mismatch is small and explainable, continue. If mismatch is major (different branch, unrelated deltas, missing files), ask one minimal clarification question before edits.

Step 4: Execute in strict order

1. Start with Next Steps item #1.
2. Keep scope fixed to handoff goal.
3. Do not re-architect unless blocked by correctness.
4. Re-run relevant validation commands listed in handoff.
5. If blocked by an unresolved decision, ask exactly one focused question.

Step 5: Update handoff artifact before yielding

At pause/completion:

1. Update the latest handoff file in place.
2. Refresh Current State, Next Steps, and Errors Encountered.
3. Remove completed items; keep remaining items actionable.
4. Keep content factual and concise.
5. If work is complete, set status: done and clear the matching CURRENT pointer.
6. If work is complete, update the matching INDEX.md row to status: done.
7. If work is paused and a fresh handoff is needed, create the new handoff, set the old file to status: paused, move CURRENT to the new file, and update both rows in INDEX.md.
8. If work is truly replaced by a new handoff in the same stream, set the old file to status: superseded, write superseded_by: <new path>, move CURRENT to the new file, and update both rows in INDEX.md.

Do not create extra summary files unless explicitly requested.

Output contract to user

When reporting takeover status, respond with:

Using handoff: <path>

## Goal
<one sentence>

## Current Step
<the exact Next Steps item being executed>

## Parallel Streams
<none OR one line per paused/orphan handoff>

## Blockers
<none OR one-line blocker>

Anti-patterns

• Starting implementation before checking current git state.
• Ignoring Decisions Made and re-opening settled trade-offs.
• Mixing new feature requests into handoff continuation.
• Updating many files before finishing Next Steps item #1.
• Writing a new handoff file when an existing one should be updated.
• Scanning the entire handoff directory when CURRENT and INDEX.md already provide the active stream and compact metadata.
• Reading the full body of every historical handoff when the index already provides status and goal summaries.

Example

Index state:

• CURRENT → .trellis/handoffs/2026-05-22-12-40-open-core.md
• INDEX.md row for onboarding says status: orphan
• INDEX.md row for billing says status: paused

Expected takeover flow:

1. Read CURRENT and detect the active path.
2. Read INDEX.md and surface the paused billing stream.
3. Open only the orphan onboarding handoff to read Goal and Next Steps.
4. Ask the user how to classify the orphan before continuing the active stream.
