# Higgsfield Pack Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** `make plugin` installs the Higgsfield CLI and its eight skills, off by default, with two toggles to turn them on.

**Architecture:** A sourced helper (`lib/higgsfield-skills.sh`) clones the upstream skills into gitignored `skills-external/higgsfield-*`; both installers call it. `lib/toggle-external.sh` links the skills on demand through two tools, `higgsfield` (media pack) and `higgsfield-websites` (single skill). Nothing is listed in `link.sh` or in a profile, which is what keeps the pack off across re-runs.

**Tech Stack:** bash, git, npm (run by the user only), shellcheck, hermetic suites under `lib/tests/` run through `make test`.

**Spec:** `docs/superpowers/specs/2026-09-30-higgsfield-pack-design.md`
**Contract:** `.claude/tasks/contracts/2026-09-30-higgsfield-pack-1412.md` (14 criteria, binding)

## How this plan is packaged

Every edit below was dry-run in a scratch copy: the final suite prints 14
PASS, shellcheck is clean, and each patch applies to the branch. The exact
bytes live in `docs/superpowers/plans/2026-09-30-higgsfield-pack.patches/`. Each task shows its code inline for reading and names
the file to apply. Apply the file, never a retyped copy.

Apply a patch with `git apply <file>`. If `git apply` refuses (the target
moved), stop and report `BLOCKED` with the error. Do not hand-merge.

## Global Constraints

- Executors never run `install-plugins.sh`, `update-all.sh`, `link.sh`, `doctor.sh`, `npm install`, `npx`, `lib/toggle-external.sh` against the real repo, or `higgsfield_sync_skills` against the network (BDR-095). The suite is the only thing that runs.
- Tests run through `make test suite=lib/tests/<file>` only. Never call a suite with `bash` directly, never prefix the command with env variables.
- Nothing about Higgsfield goes in `link.sh`, `lib/profile.sh`, `lib/profiles/*.profile` or `lib/effort-pins.txt` (BDR-093, BDR-079, BDR-105, BDR-107). The suite locks this.
- The skill sync sits before the last `apply_effort_pins "$REPO"` in `install-plugins.sh` and `update-all.sh` (BDR-108, BLK-024).
- `lib/toggle-external.sh` takes no new top-level `source` (LRN-178).
- The CLI token never reaches a terminal or a log: every `higgsfield auth token` call redirects to `/dev/null`.
- House limits for new code: functions of 25 logic lines at most, 80 columns, 5 parameters, 5 locals; shellcheck clean; comments state intent.
- Commits: explicit paths only (`git add <paths>`), never `git add -A`, never `--no-verify`, no attribution trailer. The hooks push each commit.
- `CLAUDE.global.md` and `settings.json` are hand-curated (BDR-028): only the orchestrator touches them.

## Review Focus

1. A refresh while the pack is enabled: the live `skills/<name>` link must keep resolving. Pinned by `live-reads` in `SYNC_KEEPS_PARKED` (Task 2).
2. Upstream changes its layout (no `higgsfield-*/SKILL.md`): the sync must return non-zero and keep the existing copies. Pinned by `no-skills` in `SYNC_FAIL_KEEPS_COPY` (Task 2).
3. `enable higgsfield` on a machine with no CLI on PATH: links are created, one warning, exit 0. Pinned by `absent-*` in `SIGNED_OUT_WARNS` (Task 3).
4. npm holds back the package's postinstall script, so the shim exists but the binary does not: the installer must print the `--allow-scripts=` remedy. Pinned by `remedy` in `INSTALL_WIRING` (Task 4).
5. The generalised pack arms must not change what `21st` prints or does. Pinned by `PACK_21ST_UNCHANGED` (Task 3).

### Task 1: Lock entry and gitignore

**Files:**
- Modify: `plugins.lock.json` (new `higgsfield` entry before `graphifyy`)
- Modify: `.gitignore` (link side after `skills/21st-*`, source side after `skills-external/21st-*/`)

**Interfaces:**
- Consumes: nothing.
- Produces: lock key `higgsfield` with `version` (read by Tasks 4 and 5); ignore rules `skills/higgsfield-*` and `skills-external/higgsfield-*/` (LRN-025: both states of a toggleable artifact).

- [ ] **Step 1: Apply the lock patch**

### Task 2: Sync helper and its suite

**Files:**
- Create: `lib/tests/higgsfield.test.sh` (from `docs/superpowers/plans/2026-09-30-higgsfield-pack.patches/02-higgsfield.test.sh`)
- Create: `lib/higgsfield-skills.sh` (from `docs/superpowers/plans/2026-09-30-higgsfield-pack.patches/02-higgsfield-skills.sh`)

**Interfaces:**
- Consumes: nothing.
- Produces:
  - `HIGGSFIELD_SKILLS_URL` (env value wins over the upstream default).
  - `higgsfield_sync_skills <repo>`: prints the number of skills synced on stdout; returns 0 when at least one skill was synced, 1 otherwise (existing copies untouched).
  - `higgsfield_signed_in`: returns 0 when `higgsfield auth token` succeeds; prints nothing.
  - Suite helpers later tasks reuse: `expect`, `expect_has`, `expect_not`, `verdict`, `yn`, `entries`, `git_q`, `$WORK`, `$ROOT`; the file ends with a `# ── tally ──` block that must stay last.

### Task 3: The two toggles

**Files:**
- Modify: `lib/tests/higgsfield.test.sh` (toggle cases + `OFF_BY_DEFAULT_WIRING`, inserted above the tally)
- Modify: `lib/toggle-external.sh` (header, `MANAGED_TOOLS`, enumerator, dispatcher, pack arms, single-symlink arms, `usage` range)

**Interfaces:**
- Consumes: the suite helpers of Task 2.
- Produces, in `lib/toggle-external.sh`:
  - tools `higgsfield` and `higgsfield-websites` for `status | enable | disable | list`.
  - `higgsfield_skills`: prints every `skills-external/higgsfield-*` holding a `SKILL.md`, minus `higgsfield-websites`.
  - `pack_skills <tool>`: prints the members of `21st` or `higgsfield`.
  - `pack_cli_hint <tool>`: warns (never fails) when the pack's CLI is missing or signed out.
  - Messages: `<tool> enabled (<n> skills: <r> restored, <l> linked)`, `<tool> disabled (<n> skills parked)`, `<tool> already enabled`, `<tool> already disabled`, `<tool> pack not installed in <repo>/skills-external — run: make plugin` (LRN-007: the error names the path checked).

- [ ] **Step 2: Run, confirm the new cases fail**

Run: `make test suite=lib/tests/higgsfield.test.sh`
Expected: `PASS=5 FAIL=7`. The four `SYNC_…` cases and `OFF_BY_DEFAULT_WIRING` PASS. `STATUS_STATES`, `ENABLE_PACK_EXCLUDES_WEBSITES`, `ENABLE_WEBSITES_ALONE`, `DISABLE_PARKS`, `SIGNED_OUT_WARNS`, `ENABLE_MISSING_ERRS` FAIL (the script answers `unknown` / `Unknown tool`), and `PACK_21ST_UNCHANGED` fails on `hf-apart` alone (`unknown` instead of `missing`).

- [ ] **Step 3: Apply the toggle patch**

Run: `git apply docs/superpowers/plans/2026-09-30-higgsfield-pack.patches/03-toggle-external.patch`

- [ ] **Step 4: Run the suite and the four suites that copy this script**

Run, one command per suite:

make test suite=lib/tests/gstack-removed.test.sh
make test suite=lib/tests/profile-set-managed.test.sh
make test suite=lib/tests/profile-default.test.sh
```
Expected: `PASS=12 FAIL=0` for the Higgsfield suite, and each of the four others ends green (make status 0).

- [ ] **Step 5: Shellcheck and the help text**

Run: `shellcheck lib/toggle-external.sh lib/tests/higgsfield.test.sh && sed -n '3,26p' lib/toggle-external.sh | tail -3`
Expected: no shellcheck output; the last three lines shown are the `21st`, `higgsfield` and `higgsfield-websites` tool lines.

git add lib/toggle-external.sh lib/tests/higgsfield.test.sh
git commit -m "feat(toggle): higgsfield and higgsfield-websites toggles"

### Task 4: Installer step 8.6 and the login tests

**Files:**
- Modify: `lib/tests/higgsfield.test.sh` (`INSTALL_WIRING`, above the tally)
- Modify: `install-plugins.sh` (Step 6 login test, new Step 8.6 before Step 8.7, Step 8.7 login test, one summary line)

**Interfaces:**
- Consumes: `higgsfield_sync_skills`, `higgsfield_signed_in`, `HIGGSFIELD_SKILLS_URL` (Task 2); lock key `higgsfield` through the existing `pinned_version` (Task 1); the installer's `ok | info | warn | err` helpers and `$REPO`.
- Produces: Step 8.6 (CLI install, skill sync, login offer on a terminal stdin); login offers of Steps 6 and 8.7 reachable under the `tee` redirect (`[ -t 0 ]` alone, BDR-093 TTY-only login kept).

- [ ] **Step 1: Add the failing case**

Run: `git apply docs/superpowers/plans/2026-09-30-higgsfield-pack.patches/04-suite.patch`

### Task 5: Refresh on `make update`

**Files:**
- Modify: `lib/tests/higgsfield.test.sh` (`UPDATE_WIRING`, above the tally)
- Modify: `update-all.sh` (new block 7.3b before 7.4)

**Interfaces:**
- Consumes: `higgsfield_sync_skills` (Task 2); lock key `higgsfield` (Task 1); the script's `ok | warn | info` helpers and `$REPO`.
- Produces: block 7.3b. It skips when the CLI is absent, replaces only `skills-external/` sources (a parked pack stays parked), and runs before the effort-pins re-apply (BDR-108).

- [ ] **Step 1: Add the failing case**

### Task 7: README and CHANGELOG

**Files:**
- Modify: `README.md` (new `### Higgsfield CLI` after the 21st section)
- Modify: `CHANGELOG.md` (`[Unreleased]`: one bullet under Added, Security, Fixed)

**Interfaces:**
- Consumes: the names fixed by Tasks 3 to 6.
- Produces: user documentation. Prose follows `rules/writing-style.md` (BDR-085): no em-dash, no "it's not X, it's Y", no decorative bold.

+
+```bash

+[higgsfield-ai/skills](https://github.com/higgsfield-ai/skills) into
+`skills-external/higgsfield-*`. `make update` refreshes the CLI and the
+skills, and `make doctor` reports the CLI and its session. The copies are
+machine-owned and gitignored. They follow upstream `main`, so a prompt
+change arrives with no diff to review.
+
+The pack is off by default and belongs to no profile. It costs nothing until
+you ask for it, and no `profile set` touches it:

+```bash
+bash lib/toggle-external.sh enable higgsfield            # 7 media skills
+bash lib/toggle-external.sh enable higgsfield-websites   # landing-page aid

+
+`higgsfield` turns on generate, soul-id, product-photoshoot, brandkit,
+marketplace-cards, video-explainer and youtube-thumbnail.
+`higgsfield-websites` is kept apart. Here it helps with landing pages inside
+the design stack (assets, references), and `higgsfield website
+create|deploy|publish` stays unused. Claude enables either toggle itself on
+an explicit ask (Skill routing in `CLAUDE.global.md`) and checks the price
+with `higgsfield generate cost` before a paid run.
+
+The skills are cloned, not installed with `npx skills add`: that installer
+links all eight skills into `~/.claude/skills` on every refresh, which would
+undo the off-by-default state.

 ## [Unreleased]
 
 ### Added
+- **Higgsfield pack, off by default**: `make plugin` installs the `@higgsfield/cli` CLI (Step 8.6) and clones the eight skills of higgsfield-ai/skills into `skills-external/higgsfield-*` through the new `lib/higgsfield-skills.sh`; `make update` refreshes both; `make doctor` reports the CLI and its session at info level. The pack belongs to no profile: `lib/toggle-external.sh enable higgsfield` links the seven media skills, `enable higgsfield-websites` the landing-page aid, and no `profile set` or `make link` re-enables either. `CLAUDE.global.md` routes explicit media-generation asks to it. Hermetic suite `lib/tests/higgsfield.test.sh`.
 - **Effort round (BDR-108)**: every skill carries an entry level next to its model pin. `lib/effort-pins.txt` (map) + `lib/effort-pins.sh` (idempotent re-apply after the last vendoring step of `install-plugins.sh` and `update-all.sh`) replace the hardcoded brainstorming/writing-plans loop and extend the pins to the design stack (high, one level per stack since the last loaded wins), superpowers, agent-skills and the 21st pack; `skills-perso` low, `pdf-translate` medium, `site-motion` high; doctrine: the design stack loads paired with the first Read (a lone Skill call applies nothing). Model pins stay tier aliases: the latest version of a tier is also the cheapest or same-priced, so the quality/price trade-off is tier × effort, never version. `lib/effort-audit.py` prints thinking coverage per scope (sub-agent records carry no thinking count on ~90 % of requests: EVAL-037's "executors stay cheap" was a measurement gap, not a finding).
 - **Effort tiering (BDR-107)**: reasoning effort routed per role and per phase. Session default `high`; `effort:` pins on the 20 repo-authored agents; entry level on 28 tracked user-invoked skills plus the two vendored superpowers skills (re-applied by `install-plugins.sh` after resync); five shifter skills `effort-low` … `effort-max` loaded at phase boundaries per `lib/effort-shift.md`, always sent with the step's first tool call (a lone Skill call is a no-op on 2.1.283), with `max` at the verify-secure caps and ship-feature 4b; `/effort-max` as the turn-scoped relaunch lever; statusline shows the live level; session banner warns when `CLAUDE_CODE_EFFORT_LEVEL` silences the pins; census `lib/tests/effort-routing.test.sh`; transcript audit `lib/effort-audit.py`.

 ### Fixed
+- `install-plugins.sh` never offered the ctx7 and 21st logins: both blocks required stdout to be a terminal, and stdout is the `tee` pipe of the install log. They now test stdin alone, as `update-all.sh` already did.
 - `lib/effort-pins.sh` residual LOW (security re-gate of BDR-108): INT/TERM trap removes the mktemp sibling and exits 130 (never an EXIT trap, the installer owns one); the post-write re-read message no longer claims CRLF and is reached by a stubbed unit test; the rejected map line is printed through `printf '%q'` so a caller's `echo -e` cannot interpret map content; the fixture suite guards its `mktemp -d` and skips the read-only case visibly under root.
 - `update-all.sh` re-fetched the vendored skills at every run but never re-applied the effort pins: brainstorming/writing-plans lost their xhigh until the next `make plugin` (BDR-107 gap, closed by `lib/effort-pins.sh`).
