Dev B Kickoff Prompt — CLI Tail (Cycle 2) Stream B

Paste everything below the --- line into a fresh Claude Code terminal as the first user message.

---

You are a senior developer owning Stream B of the CLI-tail cycle-2 release.

Stream B is Plan B Phases 4, 5, 6 — session/manifest discipline. Three phases, S-M effort each, total mid-day to multi-day:

• Phase 4 — Vault::after_manifest_change(&self, manifest: &Manifest) wrapper that funnels the seven manifest-mutation sites in commands/{add,edit,trash,attach,settings,import}.rs through one save_manifest + groups-cache write path. Marks save_manifest as pub(crate) (or renames it save_manifest_raw) so callers must use the wrapper.
• Phase 5 — Single canonical ParamsFile in crates/relicario-cli/src/session.rs, replacing the two-definition split between commands/init.rs (write side) and session.rs:114 (read side). Adds Serialize + Deserialize, for_new_vault constructor, into_kdf_params inversion. On-disk JSON format must round-trip with current params.json files.
• Phase 6 — Batched purge in cmd_purge and cmd_trash_empty. Renames purge_item to purge_item_filesystem (filesystem mutation only); the callers accumulate paths and run a single git_run(...["rm", "-rf", "--ignore-unmatch", paths...]) plus git_run(...["add", "manifest.enc"]) plus one git_run(...["commit"]) per batch. A 50-item trash empty should fire 3 git invocations total, not 150.

The phases are defined in docs/superpowers/specs/2026-05-04-cli-restructure-design.md under "Phase 4", "Phase 5", "Phase 6". Internal sequencing: Phase 4 before Phase 6 (Phase 6 uses after_manifest_change); Phase 5 is independent of 4 and 6.

A PM in another terminal coordinates you with Dev-A (Plan B Phase 3) and Dev-C (Plan B Phases 7, 8). With the relay server running, you communicate via post_message / read_messages directly — no user copy-paste needed.

Setup (do this first)

cd /home/alee/Sources/relicario
git fetch
git checkout main
git pull
git worktree add ../relicario.cli-tail-stream-b -b feature/cli-tail-stream-b-session-manifest
cd ../relicario.cli-tail-stream-b
pwd  # should print /home/alee/Sources/relicario.cli-tail-stream-b

ALL subsequent work happens in /home/alee/Sources/relicario.cli-tail-stream-b. Force-cd subagents into this directory — CLAUDE.md has a memory rule that subagent prompts MUST start with cd /home/alee/Sources/relicario.cli-tail-stream-b so subagents don't accidentally commit to main. Non-negotiable.

Today: 2026-05-09. Project rules in CLAUDE.md apply.

Relay server

A message-bus MCP server is running on localhost:7331. You have three native tools:

• post_message(from, to, kind, body) — push a message; your from is always "dev-b"
• read_messages(for) — drain your inbox; call with for="dev-b" before each task
• list_pending(for) — check inbox count without consuming

Recipients: pm, dev-a, dev-b, dev-c. Use these instead of asking the user to copy-paste. Before starting each task: read_messages(for="dev-b"). After emitting any status/question block: post_message(from="dev-b", to="pm", kind="status"|"question", body="...").

Fallback: If the relay MCP tools are not registered in your session, use the Python shim:

cd /home/alee/Sources/relicario/tools/relay
python3 call.py post_message '{"from":"dev-b","to":"pm","kind":"status","body":"..."}'
python3 call.py read_messages '{"for":"dev-b"}'

Cycle-1 lessons baked in (read once):

• Prefer single-line body content when posting to the relay. Some inbox-monitor scripts use strict JSON parsers that reject embedded \n literals. Use periods between sentences and -- for stronger breaks; reserve actual newlines for STATUS UPDATEs you're printing locally only.
• If you build your own inbox-monitor in Python: f-strings cannot contain backslash-escaped quotes inside brace expressions. Use single quotes inside: {m.get('from')} not {m.get(\"from\")}. Cycle-1 dev-a and dev-b both hit this; documenting once here.

Required reading (in order)

1. CLAUDE.md — project rules
2. docs/superpowers/coordination/2026-05-09-cli-tail-coordinator.md — partition spec; confirms your scope is Phases 4, 5, 6 only
3. docs/superpowers/specs/2026-05-04-cli-restructure-design.md — Plan B (read the whole plan; execute Phases 4, 5, 6)
4. docs/superpowers/reviews/2026-05-04-architecture-review.md — synthesis (skim only)
5. docs/superpowers/reviews/2026-05-04-dev-b-notes.md — DEV-B's full notes; the relevant sections are refresh_groups_cache discipline, ParamsFile dedup, batched purge

Execution mode

Use subagent-driven-development. Invoke superpowers:subagent-driven-development and follow it: fresh subagent per phase, two-stage review between phases.

Every subagent prompt MUST start with:

cd /home/alee/Sources/relicario.cli-tail-stream-b

…before any other instruction.

Your scope and boundaries

In scope: Plan B Phases 4, 5, 6.

Out of scope:

• Phase 3 (Dev-A owns) — prompt_or_flag<T> + build_*_item compression
• Phases 7, 8 (Dev-C owns) — parser migration to relicario-core, base32 dedup, WASM exports
• Anything outside Plan B Phases 4-6. If you trip over an out-of-scope issue, file a ## QUESTION TO PM block and keep moving.

Hard rules:

• Phase 5 must round-trip with existing on-disk params.json — write a fixture-string test that reads a known-current params.json and asserts the canonical struct parses it identically. On-disk format change would break existing vaults.
• Do not change CLI external behaviour — all existing crates/relicario-cli/tests/* integration tests must pass without modification.
• The groups.cache plaintext "failures silently swallowed" doc-comment from current helpers.rs:90-93 must be preserved on the new after_manifest_change wrapper. Don't change the policy.
• Do not merge your branch to main. The PM owns merges.
• Do not push --force or run git reset --hard. Per CLAUDE.md: ask first.

Internal phase sequencing (within Stream B):

• Phase 5 (ParamsFile) is independent — ship first to get it out of the way, OR last for diff-locality with the session-touching Phase 4. Either is fine; pick whichever reviews more cleanly.
• Phase 4 (after_manifest_change) before Phase 6 (batched purge). Phase 6's commit logic relies on the wrapper.

Coordination protocol

You are one of four terminals. The PM coordinates you with Dev-A and Dev-C.

Narration discipline. STATUS UPDATEs at task boundaries are the floor, not the ceiling. Also emit Status: IN-PROGRESS updates at meaningful in-flight moments:

• When you dispatch a subagent
• When a subagent returns with a decision worth flagging (a found-but-unexpected coupling, a trade-off taken)
• When a sub-task completes (e.g. after_manifest_change wrapper landed; first manifest-mutation site converted; ParamsFile round-trip test green)
• When you change direction or hit something unexpected
• When you start a new phase

The Notes field should narrate WHAT and WHY. Three sentences max. Examples of useful: "Phase 5 fixture test caught that format_version was previously emitted but never read; preserved the field but kept the read side tolerant"; "found one manifest-mutation site in commands/import.rs that did NOT call refresh_groups_cache historically (DEV-B notes flagged 7 sites; this is an 8th — surfacing as a question)." Print every STATUS UPDATE locally too.

At every task boundary AND every meaningful in-flight moment: call read_messages(for="dev-b"), then post and print using:

## STATUS UPDATE — DEV-B
Time: <iso8601>
Branch: feature/cli-tail-stream-b-session-manifest
Task: <phase number / sub-step>
Status: STARTED | IN-PROGRESS | DONE | BLOCKED | REVIEW-READY
Last commit: <short sha + first line>
Tests: <green | red (which failed) | N/A>
Notes: <WHAT and WHY — 3 sentences max>

For PM input mid-task:

## QUESTION TO PM — DEV-B
Time: <iso8601>
Context: <what task, what decision point>
Options: <A: ... / B: ... / C: ...>
Recommended: <your pick + one-sentence rationale>
Blocker: yes | no

Authority within Phases 4-6

You don't need PM permission to:

• Execute sub-steps per Plan B's Phases 4, 5, 6
• Make implementation decisions consistent with Plan B
• Write tests, refactor your own code, fix bugs you introduce
• Push commits to your feature branch

You do escalate when:

• A scope question outside Plan B Phases 4-6
• A test you can't make green after honest debugging
• A discovered bug not in Plan B
• Anything destructive (per CLAUDE.md)
• Before opening the PR for review
• If you find an unexpected manifest-mutation site beyond the seven DEV-B notes flagged (likely surfaces in Phase 4)

Final steps before REVIEW-READY

Run the project's full validation:

cd /home/alee/Sources/relicario.cli-tail-stream-b
cargo test --workspace
cargo clippy --workspace
cargo build -p relicario-wasm --target wasm32-unknown-unknown

All three must be green / clean. Then push and open the PR:

git push -u origin feature/cli-tail-stream-b-session-manifest
gh pr create --base main --head feature/cli-tail-stream-b-session-manifest --title "refactor(cli): session/manifest discipline (Plan B Phases 4, 5, 6)" --body "$(cat <<'EOF'
## Summary
- Phase 4 — `Vault::after_manifest_change` wrapper funnels seven manifest-mutation sites; `save_manifest` made `pub(crate)` so callers can't bypass the wrapper
- Phase 5 — Single canonical `ParamsFile` in `session.rs` replaces the two-definition split; on-disk JSON round-trips with existing vaults (fixture-string test)
- Phase 6 — Batched purge: a 50-item `trash empty` now fires 3 git invocations instead of 150

## Plan B Phases 4-6
Implements `docs/superpowers/specs/2026-05-04-cli-restructure-design.md` Phases 4, 5, 6.
See `docs/superpowers/coordination/2026-05-09-cli-tail-coordinator.md` for cycle-2 partition.

## Test plan
- [x] cargo test --workspace
- [x] cargo clippy --workspace
- [x] cargo build -p relicario-wasm --target wasm32-unknown-unknown
- [x] params.json round-trip test against existing on-disk format
- [x] `trash empty` with N items produces 1 commit (regression invariant)
- [x] Existing crates/relicario-cli/tests/* pass without modification

Emit a ## STATUS UPDATE with Status: REVIEW-READY and the PR URL.

First action

After reading: emit a ## STATUS UPDATE confirming setup complete (worktree created, plan absorbed, on feature/cli-tail-stream-b-session-manifest), then start Phase 4 (or Phase 5 if you prefer to ship the independent piece first — call it out in the status update).
