Confirm

Role

The single home for every interactive user gate. The run controller never prompts - it BLOCKS with status=blocked + blocked_reason and hands the user here. confirm reads blocked_reason, runs exactly the matching AskUserQuestion round, persists each answer into state.decisions (sticky - never re-asked on resume), clears the block, advances current_step, and re-invokes run via the Skill tool. It owns: the filter-gate round (G-FILTER, G-NAMING, G-ONBOARD, G-MEMORIES) + GROUPED-vs-STANDALONE assignment + G-COST; and the browser-accelerator round (G-AUTO-REOFFER, G-LOGIN/G-BROWSER).

Preflight: there must be a block to clear

Read state.status and state.blocked_reason. If status != blocked, print "Nothing to confirm - run /claude-migrate:run <run-name> to advance, or /claude-migrate:progress <run-name> to see where you are." and exit without asking anything. Decisions already present in state.decisions are STICKY - never re-ask them.

Invocation

/claude-migrate:confirm

<run-name> is required. RUN_PATH=".planning/claude-migrate/<run-name>". Abort if state.json is missing.

Protocol

Step 1: Read the block + state

STATUS=$(bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh get "$RUN_PATH" .status)
REASON=$(bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh get "$RUN_PATH" .blocked_reason)
OUT_MODE=$(bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh get "$RUN_PATH" .output.mode)

Dispatch by REASON:

• filter-gate → Step 2 (the filter-gate round + G-COST).
• auto-reoffer → Step 3 (G-AUTO-REOFFER, then login/browser).
• login or browser-lost → Step 4 (G-LOGIN/G-BROWSER only).
• cost → Step 2f (G-COST only, then re-evaluate).
• anything else → print "This block is not a user gate - see /claude-migrate:health <run-name>." and exit.

Step 2: The filter-gate round (blocked_reason == "filter-gate")

Run these in order. Each is one AskUserQuestion call; each answer is persisted via state.sh set .decisions.<key>.

2a. G-FILTER - what migrates (one summary question; per-item legend loop on demand)

First read the preflight scores to build the summary: count KEEP + REFERENCE vs DROP from value/*.json, and surface any duplicate clusters (representative = lowest idx). Ask ONE summary question. Header: "Confirm what migrates", body: "Migrate N (KEEP/REFERENCE), skip M (DROP: empty / starter project / tool-only / near-duplicate)?"

• Option A (DEFAULT): Accept recommended - keep the scored KEEP/REFERENCE, drop the DROP set.
• Option B: Review per-item - enter the per-item legend loop: for EACH item, print the FULL legend (UNNN, name, bucket, value, confidence, reason, any looks_duplicate_of) BEFORE its AskUserQuestion call (not batched). Duplicate clusters are SURFACED for an explicit keep/drop pick - NEVER auto-dropped. An empty-body-but-meaningful-name chat is a low-confidence KEEP candidate (M-6).

Apply the decision: move DROP units to units/dropped/ (never delete the source); KEEP/REFERENCE units stay in the queue. Update counters.kept / counters.dropped via state.sh inc/dec so the §3.3 invariants hold.

2b. GROUPED-vs-STANDALONE assignment (C2 - explicit, never re-derived)

For each KEEP/REFERENCE unit, ask whether it joins a destination project (GROUPED) or stays a standalone chat (DEFAULT = STANDALONE). Present the available PNN__slug projects (from project/). Persist the user-confirmed map:

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" '.decisions.project_assignment."UNNN"' '"PNN__slug"'   # GROUPED
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" '.decisions.project_assignment."UNNN"' null               # STANDALONE

This map is the SOLE authority for grouping - preflight-value may not emit GROUPED, and resume never re-derives it.

2c. G-NAMING - how migrated chats are named [default keep]

Header: "How should migrated chats be named?"

• Option A (DEFAULT): Keep original - derive a title only when a name is empty/generic.
• Option B: Custom (date + disambiguator) - a structured pick with a prefilled worked example Name DD.MM tag (UX M-4). Store the scheme string in config.yaml and set:

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .decisions.naming_convention '"keep"'            # or "custom:<scheme>"

2d. G-ONBOARD - OK-protocol onboarding [default ok-then-strip]

Header: "Use the OK-protocol onboarding (reply OK to each brief, then auto-remove that line after seeding)?"

• Option A (DEFAULT): ok-then-strip - emit BOTH instruction variants (migration + steady).
• Option B: I'll strip it myself.
• Option C: No OK-protocol.

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .decisions.onboarding_ok_protocol '"ok-then-strip"'  # | strip-myself | none

2e. G-MEMORIES - only if memories.json exists [default skip]

Skip this question entirely unless $RUN_PATH/source/memories.json exists. If it does, header: "Migrate account memory? (may contain stale or third-party PII)"

• Option A (DEFAULT): Skip.
• Option B: Paste to new-account memory (redact + size-check + preview first - Edge M-2, references/pii-policy.md).
• Option C: Fold into a project (same redact + size-check + preview).

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .decisions.memories '"skip"'  # | paste-to-memory | fold-into-project

2f. G-COST - deterministic cost estimate, BEFORE distill, BOTH modes (UX H-4)

The estimate is driven by the DETERMINISTIC est_tokens already in value/*.json (computed by the parser; never by a model). Compute cost_estimate (a pure function of the parsed units + active profile) and read usd_high, chats_total, and the max per-chat est_tokens. Show the gate ONLY if usd_high >= 10 OR chats_total > 75 OR any chat est_tokens > 80000; below all thresholds, silently proceed (set cost_acknowledged=true).

When shown: "Estimated $X (in-tokens Y) to distill N chats. Proceed?"

• > $25 → HARD-STOP requiring an explicit Proceed.
• > 75 chats → note "long run -> resumable batches".
• > 80k-token chat → note it will be summarized at distill. Browser seeding itself is $0 API (it consumes the destination message cap - noted later at pre-apply). On Proceed:

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .decisions.cost_acknowledged true

2g. Persist + clear the block + hand to run

Mark the filter gate confirmed, advance, clear the block, hand off:

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" '.gates.filter.user_confirmed' true
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" '.gates.filter.verdict' '"PASS"'
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .current_step distill
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .blocked_reason null
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .status running
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh checkpoint "$RUN_PATH"

Then invoke skill claude-migrate:run with argument <run-name> via the Skill tool. run advances distill -> synthesize -> build-page -> verify-gate -> ready.

Step 3: The browser-accelerator round (blocked_reason == "auto-reoffer")

Only reached when output.mode == "auto" and the run is at ready.

3a. G-AUTO-REOFFER - mandatory "looks right" ack (UX M-5)

Show the out/index.html path and 1-2 sample brief titles from briefs/*.name.txt. Ask for an explicit acknowledgement. Header: "The copy page is verified. Proceed with browser seeding?"

• Option A (DEFAULT): Looks right, proceed - sets the ack.
• Option B: Not yet - leave at ready (the copy page is already a complete success); exit without advancing.

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .decisions.auto_reoffer_ack true

3b. Login + browser probe (G-LOGIN / G-BROWSER)

Probe the browser transport + auth marker:

bash ${CLAUDE_PLUGIN_ROOT}/bin/browser-probe.sh "$RUN_PATH"

Read state.output.browser.authed and .transport. Follow ${CLAUDE_PLUGIN_ROOT}/references/login-policy.md verbatim - NEVER script credentials, 2FA, or captcha.

• Authed → continue to 3c.
• Not authed / no transport → apply the demote rules (UX H-3):
  • user_chose_auto == false (Enter-on-default AUTO) AND no browser → DEMOTE to copy-page and SAY SO: set output.mode=copy-page, print the macOS CDP launch command from the probe + "the copy page at out/index.html is your complete deliverable; to enable automation later, launch the browser and run /claude-migrate:resume <run-name>." Set status=passed, leave current_step=ready, exit.
  • user_chose_auto == true (explicitly chose AUTO) AND no browser → do NOT demote: status=blocked + blocked_reason=login, print the CDP launch command + "log into the NEW account, then /claude-migrate:resume <run-name>." Exit.

3c. Clear + advance + hand to run

bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .current_step pre-apply-gate
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .blocked_reason null
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh set "$RUN_PATH" .status running
bash ${CLAUDE_PLUGIN_ROOT}/bin/state.sh checkpoint "$RUN_PATH"

Invoke skill claude-migrate:run with argument <run-name> via the Skill tool. run runs GATE 3 (incl. dest_hash != source_hash) then apply -> finalize -> done.

Step 4: Login / browser-lost only (blocked_reason in {"login","browser-lost"})

Re-probe (Step 3b). If now authed, clear blocked_reason, set status=running, and hand to run (it resumes from pre-apply-gate or apply). If still not authed, re-print the login-policy halt + CDP launch command and exit (do NOT script login).

Hard rules

• Print the FULL legend per item before each per-item AskUserQuestion call in the G-FILTER review loop - never batch the legend across items.
• GROUPED-vs-STANDALONE is captured here as an EXPLICIT user choice into decisions.project_assignment and is NEVER re-derived on resume.
• G-COST fires BEFORE distill in BOTH modes, driven by deterministic est_tokens only - never by a model score. > $25 is a HARD-STOP needing explicit Proceed.
• G-OUTPUT phantom "both" is forbidden; the only two output modes are auto and copy-page.
• Never script login / 2FA / captcha - detect, block, ask, resume (references/login-policy.md).
• Never demote silently: Enter-on-default + no browser demotes WITH a message; explicit-AUTO + no browser blocks (no demote).
• Every answer is sticky in state.decisions and is never re-asked on resume.
• Always clear blocked_reason and set status=running before handing to run; never advance the pipeline yourself beyond the one step the gate unlocks.
• Never mutate state.json outside bin/state.sh. Never reference any specific domain; labels come from config.yaml.
