Sessions are created one at a time, each checked with `crow list-worktrees` (the #1301 race). Every coder prompt carries the cascade contract: one PR scoped to its ticket with `Closes #N`, a human reviewer requested (`--reviewer`, default `dgershman`), no self-approval, and the gate's label rule. With `--gate human`, the coder leaves `crow:merge` off and the reviewer merges by hand. With `--gate auto`, the coder adds `crow:merge` so Crow's auto-merge watcher merges on green. When `--gate` is omitted, the skill picks `auto` only if the base branch requires an approving review and the watcher is on. A background watcher (`cascade.sh watch`) releases the next wave only once every PR in the current wave has merged. It also reports PRs that break the contract, such as `crow:merge` added before a human approval. Re-running the skill resumes from live GitHub and Crow state without launching a ticket twice. `--dry-run` prints the wave map only, `--explore` runs a mapping pass over one wave, and `--wave ` starts at a later wave. - CROW-1294 — **Drag extra Managers in the left sidebar to reorder them.** A grip on each extra Manager row (when there are two or more) drops that row above or below another extra Manager. The order is written into the stored session array, so a reload shows it. The nav pill stays the primary Manager (`is_primary_manager` / the well-known id), and a new extra Manager still appears at the end until it is moved. Jobs, Active, Reviews, In Review, and Completed are not part of the drag. Sidebar order in the session switcher lists Managers the same way. CLI: `crow reorder-manager --session --before ` or `--after `. - CROW-1293 — **Delete on the Manager session header.** An extra Manager's header shows a red **Delete** immediately left of Reload, and immediately right of **Mark Scratch Done** when a linked Scratch item is still open. The click is the same confirm dialog and `delete-session` path as the row menu. The primary Manager still offers Delete; the daemon rejects it with "Cannot delete manager session" and the header surfaces that failure.

A second failure stops the wave — report it rather than looping. +6. **Post the cascade comment** on the ticket, unless `--no-comment` (see **Ticket comment**). + +A setup failure for one ticket doesn't undo the others. Report it, and the next `/crow-cascade-epic` run offers the ticket in `to_launch` again (it has no session). + +#### Why sessions are created one at a time + +Creating many sessions back to back hit a lost-update race: `crow add-worktree` succeeded, then the daemon's store-reload poll dropped the fresh row before `setup.sh`'s launch check read it (corveil/crow#1301). #1301 is fixed in Crow builds that include #1308. The skill still creates sessions **sequentially, with the `list-worktrees` check** — it can't tell which `crowd` build is running, and a wave is only a handful of tickets, so the parallel speedup isn't worth a lost registration. **Never** hand a wave to `/crow-batch-workspace`. + +### Phase 6: Arm the wave watcher + +Claude Code — a Bash call with `run_in_background: true`, `timeout: 7200000`, and `dangerouslyDisableSandbox: true`: + +```bash +bash .claude/skills/crow-cascade-epic/cascade.sh watch --plan-file {devRoot}/.claude/cascades/{slug}.json --wave {current_wave} +``` + +It polls every 2 minutes, prints a line whenever a ticket's state or drift changes, and exits within 110 minutes. You're re-invoked when it exits: + +| Exit | Last line | Do | +|---|---|---| +| `0` | `WAVE n COMPLETE — release wave n+1: …` | Tell the operator in one line, then go back to **Phase 4**: status → launch `to_launch` → arm a watcher on the new `current_wave`. | +| `10` | `WAVE n still open after …s — re-arm the watcher` | Run the same command again. Say nothing unless a streamed line needs action. | +| `3` | `WAVE n BLOCKED — needs the operator: …` | Stop and ask about the blocked tickets (see Phase 4). | +| `2` | A JSON error, or `WAVE n status unavailable — …` | Report it. The watcher couldn't read the wave, so it released nothing — see **Error Handling**. | + +A wave whose change lands as a GitLab MR never completes on its own — advance it by hand, per **Limitations**. Act on any `⚠ contract:` line in the stream per **Contract drift**. Arm **one** watcher per epic — if one you started for this plan file is still running, don't start another. + +Without background re-invocation (Cursor, Codex, and other Manager harnesses), skip the watcher. Tell the operator to re-run `/crow-cascade-epic {epic_url}` after a wave merges; it picks up exactly where the cascade stands. + +### Phase 7: Report + +After planning, after each launch, and when a wave releases: + +``` +## Cascade: {epic_ref} — {epic_title} + +Gate: human — @dgershman reviews and merges; no crow:merge (inferred: `main` requires no approving review) +Plan: {devRoot}/.claude/cascades/{slug}.json + +| Wave | Ticket | Title | Depends on | State | Session | +|------|--------|-------|------------|-------|---------| +| 1 | T1 #619 | Design doc / ADR | — | launched | corveil-cloud-terraform-619-nat-egress-adr (3f2a…) | +| 2 | T2 #620 | SG + NACL hardening | T1 | waits on wave 1 | — | +| 2 | T3 #621 | Parameterize ECS task networking | T1 | waits on wave 1 | — | + +Watcher: armed on wave 1. +``` + +Include full session IDs somewhere in the report (the table may abbreviate), plus any drift, blocked tickets, `crow:auto` warnings, and setup failures. + +## Cascade Instructions (coder prompt) + +Replaces the `## Instructions` of `/crow-workspace`'s First Prompt Template, with a `## Cascade Contract` section right before it. `{closes_ref}` is `#{number}`, or `{owner}/{repo}#{number}` when the PR lands in a different repo from the ticket; `{base_branch}` and the rest are the same values `/crow-workspace` substitutes. + +~~~markdown +## Cascade Contract + +This ticket is **{label} of epic {epic_ref}** ({epic_url}) — wave {wave} of {wave_count} in a dependency-gated cascade. {dependency_line} + +The next wave starts only when this wave's PRs **merge**, so the PR you open is what the cascade waits on: + +- **One PR, this ticket only.** Base `{base_branch}`, `Closes {closes_ref}` in the body.

Don't dismiss reviews yourself. | +| `N open PRs … exactly one PR per ticket` | Tell the coder, and let the operator pick which PR survives. | +| `PR #X merged without an approval from anyone but its author (human gate)` | Tell the operator right away: unreviewed code is now on the default branch, and only they can decide whether to revert it. The ticket still counts as merged — its change has landed, and holding dependents wouldn't undo it. (Who clicked merge isn't checked: Crow's auto-merge runs as the author even after a human approves.) | +| `PR #X still open although #Y already merged this ticket` | The ticket is satisfied and its wave can release, but the stray PR could still merge later.

Re-run with `--wave 1` to undo that. +- **Comments post once**, thanks to the `` marker. + +## Error Handling + +| Error | Response | +|---|---| +| `cascade.sh plan` → `dependency cycle among: …` | Stop. Show the cycle; the operator decides which edge is wrong. | +| `cascade.sh plan` → `… depends on X, which is not in the plan` | Add X as an `"external": true` ticket, or drop the edge if the reference was not a dependency. | +| `cascade.sh` → `jq is required` / `jq 1.6 or newer is required` | Install or upgrade jq (`brew install jq`; macOS 15+ ships 1.7 at `/usr/bin/jq`). Check which one wins with `command -v jq`. | +| `crow list-sessions failed …` (or `watch` exits 2 with it) | Crow didn't answer, so `status` couldn't tell which tickets already have a session. Nothing was launched or released. Check that the daemon is up (`crow list-sessions`), then re-run `status` or re-arm the watcher. | +| `status filter failed: …` (or `watch` exits 2 with `status unavailable`) | The installed jq couldn't run the status filter. Nothing was released — `watch` fails closed rather than guess. Check `jq --version`, fix it, then re-run `status`. | +| `setup.sh` error | Per `/crow-workspace` → **Error Handling**, and the Phase 5 recovery for `launch_agent`. | +| `status` shows `unknown` | Transient GitHub failure. Re-run `status`; an `unknown` ticket never releases a wave. | +| Reviewer = the pushing account | Stop and ask for another reviewer (Phase 2). | +| `watch` exit 3 | Blocked tickets — ask the operator (Phase 4). | + +## Limitations + +- **Merge tracking reads GitHub only.** `cascade.sh` resolves ticket state from GitHub issues and PRs: the PRs that close the issue, plus any PR registered on one of the ticket's work sessions. A **Jira** ticket whose code lands on GitHub works through that registered PR. +- **A GitLab merge does not release its wave.** `cascade.sh` can't read GitLab issues or MRs, so a ticket whose change lands as a GitLab MR always reads as `no_pr`. (A GitLab ticket whose code lands as a GitHub PR is tracked through the registered PR, like Jira.) Once the ticket has a session, it also drops out of `to_launch`, so its wave never completes. Neither the watcher nor a plain re-run can advance past it — don't arm a watcher on that wave expecting it to fire. Advance by hand instead: + 1. Confirm each GitLab MR in the wave merged: `GITLAB_HOST={host} glab mr view {iid} --repo {org/repo}`. + 2. Run `status` and check that every **other** ticket in the wave is satisfied. + 3. Only then run `/crow-cascade-epic {epic_url} --wave {n+1}`. `--wave` skips the **whole** wave, so running it early would also skip an unmerged GitHub ticket in that wave. +- **The gate follows the default branch.** A PR merged into another base doesn't close the issue, and only counts when it's registered on one of the ticket's sessions. + +## Worked example: corveil-cloud-terraform#618 + +The NAT-removal epic, which this skill packages, was run by hand first: + +``` +/crow-cascade-epic https://github.com/corveil/corveil-cloud-terraform/issues/618 +``` + +1. **Phase 1.** The epic has no GitHub sub-issues or `blocked_by` links. Its body carries the task list (`T1 — #619` … `T8 — #626`) and a `Dependency order (waves)` section, and each child says `Depends on T2, T3.` (and so on). The edges come out as T1 → T2, T3 → T4, T5, T6 → T7 → T8. +2. **Phase 2.** `main` requires no approving review, so the gate is **`human`**, reviewer `@dgershman`. +3. **Phase 3.** `cascade.sh plan` writes `.claude/cascades/corveil-corveil-cloud-terraform-618.json`, whose tickets look like: + + ```json + {"id": "corveil/corveil-cloud-terraform#622", "label": "T4", + "url": "https://github.com/corveil/corveil-cloud-terraform/issues/622", + "title": "Move corveil-api to public subnets", + "deps": ["corveil/corveil-cloud-terraform#620", "corveil/corveil-cloud-terraform#621"]} + ``` + + It layers five waves: **1** T1 · **2** T2, T3 · **3** T4, T5, T6 · **4** T7 · **5** T8. The epic calls these Wave 0–4. +4. **Phase 5.** Wave 1 launches one session for #619. Its prompt carries the human-gate contract, and #619 gets the `🔗 Merge-gated cascade` comment. +5. **Phase 6.** The watcher streams `wave 1 · T1 … → in_review (PR #636 open)`. When @dgershman merges #636, it exits 0 with `WAVE 1 COMPLETE — release wave 2: T2 …#620, T3 …#621`. +6. The Manager launches #620, then #621 — one at a time, each with its `list-worktrees` check — and arms the watcher on wave 2. The same loop runs through PRs #638–#643. +7. When #644 (T8) merges, the watcher prints `WAVE 5 COMPLETE — that was the last wave; the cascade is done`.

Keep any short label (`T1`) the epic assigns; it becomes the ticket's `label`. +3. **GitLab / Jira:** the epic's child issues (`glab api` on the epic's issues, or `jira_search` with `parent = {KEY}`). + +Then fetch each child once — title, body, state, labels: + +```bash +gh issue view {child_url} --json number,title,body,state,labels,url +``` + +**Collect the dependency edges**, again as a union: + +1. **GitHub issue dependencies:** `gh api repos/{owner}/{repo}/issues/{number}/dependencies/blocked_by` for each child. +2. **Child bodies:** `Depends on …`, `Blocked by …`, `After …`, naming `#N`, a URL, or an epic label (`Depends on T2, T3.`). Resolve labels through the epic's task list (`T2` → `#620`). +3. **An explicit wave list in the epic** (`Wave 1: T2 and T3 — parallel`): every ticket in a declared wave depends on every ticket in the declared wave before it. Epics sometimes number waves from 0 — the plan always numbers from 1. + +If a child depends on a ticket **outside** the epic, add that ticket to the plan with `"external": true`: it gates its dependents like any other ticket, but the cascade never starts a session for it.

Then write the plan fresh from Phase 1 — the epic may have gained tickets since the last run — with the Write tool, or a heredoc: + +```bash +cat > {devRoot}/.claude/cascades/{slug}.json << 'JSON' +{ + "epic": {"url": "{epic_url}", "title": "{epic_title}"}, + "gate": "human", + "reviewer": "dgershman", + "start_wave": 1, + "tickets": [ + {"id": "{owner}/{repo}#619", "label": "T1", "url": "https://github.com/{owner}/{repo}/issues/619", "title": "…", "deps": []}, + {"id": "{owner}/{repo}#620", "label": "T2", "url": "https://github.com/{owner}/{repo}/issues/620", "title": "…", "deps": ["{owner}/{repo}#619"]} + ] +} +JSON +``` + +- `id` is `owner/repo#N` for GitHub, or the key (`MAXX-6859`) for Jira. `deps` name other tickets' `id`s. +- `url` must be the ticket's canonical URL. The helper matches sessions by `ticket_url`, and queries GitHub from it. +- `"external": true` marks a gating ticket the cascade never launches. + +Then layer it: + +```bash +bash .claude/skills/crow-cascade-epic/cascade.sh plan --plan-file {devRoot}/.claude/cascades/{slug}.json +``` + +It validates the plan and writes `wave` onto each ticket, plus a `waves` list, back into the file. It also prints the map as JSON. On `"status":"error"` (a cycle, an unknown dependency, a missing field), **stop** and show the operator the `errors` — a cycle means the epic's dependency text contradicts itself, and only a human can say which edge is wrong. + +### Phase 4: Status and the wave map + +```bash +bash .claude/skills/crow-cascade-epic/cascade.sh status --plan-file {devRoot}/.claude/cascades/{slug}.json +``` + +`status` reads GitHub and Crow — nothing in the plan file is trusted for progress. If it can't read Crow's session list, it returns an error instead of guessing, so a ticket already in flight is never offered for launch again. Otherwise it returns: + +- `tickets[]` — each with `state` (below), `satisfied`, `blocked`, `prs`, `session` (the work session whose `ticket_url` matches), `explore_session`, and `drift` (contract violations on its open PR). +- `waves[]` — `{wave, total, satisfied, complete, skipped, blocked}`. +- `current_wave` — the lowest wave that isn't complete, or `null` once `complete` is `true`. +- `to_launch` — the tickets of `current_wave` with nothing in flight: no Crow session and no open PR. **This is the list Phase 5 launches.** + +| `state` | Meaning | Satisfies the gate? | +|---|---|---| +| `merged` | A PR that closes the ticket, or one registered on any of the ticket's work sessions, merged. A second PR still open is reported as drift. | yes | +| `closed` | A human closed the ticket as completed, and no PR is still open | yes | +| `in_review` / `draft` | An open PR | no | +| `pr_closed` | Only closed-unmerged PRs. The ticket returns to `to_launch` only once it has **no** work session left — a leftover session, even a completed one, holds it (see **Idempotency and resume**). To restart it, reopen that session, or delete it and re-run. | no | +| `no_pr` | Nothing yet — and **always** when the change lands as a GitLab MR (see **Limitations**) | no | +| `closed_not_planned` | Closed as not planned / duplicate — its dependents can never release | no — **blocked** | +| `unknown` | The GitHub query failed (transient) | no — never releases a wave | + +**Print the wave map** (see **Report**), then run these checks and include what they find: + +- Any `drift` → handle per **Contract drift**. +- Any `blocked` ticket → it stalls its wave for good.

Recommend removing the label (`gh issue edit {url} --remove-label crow:auto`), and do it only with the operator's OK. + +Stop here when `complete` is `true` ("the cascade is done"), or on `--dry-run`. + +### Phase 5: Launch the current wave — one ticket at a time + +For each `id` in `to_launch`, in plan order, **finish one ticket before starting the next**: + +1. **Resolve it exactly as `/crow-workspace` does:** Step 0's ticket and comment pre-fetch, **PR Detection**, the default-branch lookup (`{base_branch}`), repo matching, the naming conventions (worktree, branch, session name), and **Resolve custom instructions** for the matched workspace. +2. **Compose the prompt:** `/crow-workspace`'s **First Prompt Template**, with its `## Instructions` replaced by the **Cascade Instructions** below, and a **`## Cascade Contract`** section inserted before them. Keep the Workspace Context table, the embedded Ticket block, and the `## Custom Instructions` rule unchanged. +3. **Write the prompt file** to `{devRoot}/.claude/prompts/crow-prompt-{session_name}.md`. +4. **Run `setup.sh`** with the same flags as `/crow-workspace` Step 2 (`--primary`, `--base-branch`, `--ticket-*`, `--prompt-content`, …) in a **single** Bash call, and wait for its JSON before moving on. +5. **Verify the worktree registration stuck:** + + ```bash + crow list-worktrees --session {session_id} + ``` + + It must list a worktree whose `branch` is the one you passed. Then `sleep 5` and check once more — the race below dropped a registration a beat *after* `add-worktree` returned. + - Row missing **after** a successful `setup.sh`: the coder is already running, so don't delete anything.

A second failure stops the wave — report it rather than looping. +6. **Post the cascade comment** on the ticket, unless `--no-comment` (see **Ticket comment**). + +A setup failure for one ticket doesn't undo the others. Report it, and the next `/crow-cascade-epic` run offers the ticket in `to_launch` again (it has no session). + +#### Why sessions are created one at a time + +Creating many sessions back to back hit a lost-update race: `crow add-worktree` succeeded, then the daemon's store-reload poll dropped the fresh row before `setup.sh`'s launch check read it (corveil/crow#1301). #1301 is fixed in Crow builds that include #1308. The skill still creates sessions **sequentially, with the `list-worktrees` check** — it can't tell which `crowd` build is running, and a wave is only a handful of tickets, so the parallel speedup isn't worth a lost registration. **Never** hand a wave to `/crow-batch-workspace`. + +### Phase 6: Arm the wave watcher + +Claude Code — a Bash call with `run_in_background: true`, `timeout: 7200000`, and `dangerouslyDisableSandbox: true`: + +```bash +bash .claude/skills/crow-cascade-epic/cascade.sh watch --plan-file {devRoot}/.claude/cascades/{slug}.json --wave {current_wave} +``` + +It polls every 2 minutes, prints a line whenever a ticket's state or drift changes, and exits within 110 minutes. You're re-invoked when it exits: + +| Exit | Last line | Do | +|---|---|---| +| `0` | `WAVE n COMPLETE — release wave n+1: …` | Tell the operator in one line, then go back to **Phase 4**: status → launch `to_launch` → arm a watcher on the new `current_wave`. | +| `10` | `WAVE n still open after …s — re-arm the watcher` | Run the same command again. Say nothing unless a streamed line needs action. | +| `3` | `WAVE n BLOCKED — needs the operator: …` | Stop and ask about the blocked tickets (see Phase 4). | +| `2` | A JSON error, or `WAVE n status unavailable — …` | Report it.

Only then run `/crow-cascade-epic {epic_url} --wave {n+1}`. `--wave` skips the **whole** wave, so running it early would also skip an unmerged GitHub ticket in that wave. +- **The gate follows the default branch.** A PR merged into another base doesn't close the issue, and only counts when it's registered on one of the ticket's sessions. + +## Worked example: corveil-cloud-terraform#618 + +The NAT-removal epic, which this skill packages, was run by hand first: + +``` +/crow-cascade-epic https://github.com/corveil/corveil-cloud-terraform/issues/618 +``` + +1. **Phase 1.** The epic has no GitHub sub-issues or `blocked_by` links. Its body carries the task list (`T1 — #619` … `T8 — #626`) and a `Dependency order (waves)` section, and each child says `Depends on T2, T3.` (and so on). The edges come out as T1 → T2, T3 → T4, T5, T6 → T7 → T8. +2. **Phase 2.** `main` requires no approving review, so the gate is **`human`**, reviewer `@dgershman`. +3. **Phase 3.** `cascade.sh plan` writes `.claude/cascades/corveil-corveil-cloud-terraform-618.json`, whose tickets look like: + + ```json + {"id": "corveil/corveil-cloud-terraform#622", "label": "T4", + "url": "https://github.com/corveil/corveil-cloud-terraform/issues/622", + "title": "Move corveil-api to public subnets", + "deps": ["corveil/corveil-cloud-terraform#620", "corveil/corveil-cloud-terraform#621"]} + ``` + + It layers five waves: **1** T1 · **2** T2, T3 · **3** T4, T5, T6 · **4** T7 · **5** T8. The epic calls these Wave 0–4. +4. **Phase 5.** Wave 1 launches one session for #619. Its prompt carries the human-gate contract, and #619 gets the `🔗 Merge-gated cascade` comment. +5. **Phase 6.** The watcher streams `wave 1 · T1 … → in_review (PR #636 open)`. When @dgershman merges #636, it exits 0 with `WAVE 1 COMPLETE — release wave 2: T2 …#620, T3 …#621`. +6. The Manager launches #620, then #621 — one at a time, each with its `list-worktrees` check — and arms the watcher on wave 2. The same loop runs through PRs #638–#643. +7. When #644 (T8) merges, the watcher prints `WAVE 5 COMPLETE — that was the last wave; the cascade is done`. A final `status` reports `"complete": true`. diff --git a/skills/crow-cascade-epic/cascade.sh b/skills/crow-cascade-epic/cascade.sh new file mode 100755 index 00000000..25182a26 --- /dev/null +++ b/skills/crow-cascade-epic/cascade.sh @@ -0,0 +1,456 @@ +#!/usr/bin/env bash +# crow-cascade-epic helper (CROW-1312) — the deterministic half of a +# dependency-gated epic cascade.
