Third-Party Notices
gstack is MIT. The files below contain material derived from Apache-2.0 and MIT
works, rewritten in gstack's voice and modified. Rewriting is not an exemption:
the license texts are in licenses/, and each file derived from an Apache-2.0
work carries a notice that it was changed. Unmodified copies (the rule-registry fixture, the
license text) carry no header and are listed here instead.
impeccable — Copyright Paul Bakaus — Apache License 2.0
https://github.com/pbakaus/impeccable
Derived, modified:
lib/design-catalog.ts: rule ids and names fromcrates/live/assets/antipatterns.json; the prose is gstack's.scripts/resolvers/design.ts: the Persuade / Operate / Read / Experience visitor modes, the craft-floor reflexes (browser surfaces, one authored motion moment, depth has an offset, tinted secondary text, space above headings, light-or-dark from the use scene), and the three-looks calibration, fromSKILL.md,reference/craft-floor.md, andreference/new-work.md, rewritten.design-consultation/sections/proposal-and-preview.md.tmpl: the font-selection procedure and the calibration paragraph, rewritten; and theSKILL.md/sections/*.mdfiles generated from these sources.
Unmodified copy:
test/fixtures/impeccable-antipatterns.json:crates/live/assets/antipatterns.jsonat commit 87d8f6d6 (engine-v0.1.3), wrapped in a_sourceprovenance object.
Not distributed: bin/gstack-design-detect.ts invokes an impeccable engine the
user installed. gstack does not ship or mirror that engine and never runs impeccable's
installer or launcher. The one download gstack can make is the engine binary
itself, only after the user accepts a design skill's one-time offer: fetched from
impeccable's own GitHub release into ~/.impeccable/bin/<version>/, verified
against the checksum pinned in lib/design-detect-contract.ts, and recorded in
the egress ledger first. gstack does not audit the engine's network behavior; the
wrapper refuses URL targets so gstack never asks it to touch the network.

Derived, modified (rules rewritten in gstack's voice and reconciled with its design rules; Elaya's fixed fonts, colors, spacing values, icon sets and signature components are not carried over):
design-html/sections/craft.md.tmpl: the Persuade intake, page archetypes, page structure, conversion and copy rules, indexing and build order from landing-page-design Part A; the content-realism, ship-floor, scale-snapping, line-break and motion rules from landing-page-design Part B, the website context of design-to-motion and the redesign-skill audit; and the generateddesign-html/SKILL.md/sections/craft.md.lib/design-lint/rules/copy.ts: the content-realism and ship-floor tells, the design lint's copy tier.design-shotgun/SKILL.md.tmpl: page archetypes as a variant axis.design-review/sections/craft-audit.md.tmpl(and the generatedsections/craft-audit.md): the redesign-skill audit of an existing site, its fix-priority order and Tailwind version check;scripts/resolvers/design-craft.ts: the Persuade conversion checks, also rendered intoplan-design-review/sections/review-sections.md; and the craft-tell entries inlib/design-catalog.ts.design-motion/SKILL.md.tmplanddesign-motion/sections/fidelity.md.tmpl,motion.md.tmplandfigma.md.tmpl(and the generateddesign-motion/SKILL.mdandsections/*.md): design-to-motion's fidelity rules, Figma layer-export table (now an optional source path), loading choreography, story loops, loop cycle, easing, checks and export formats, reconciled with gstack's one authored motion moment, content visible without script, and the slop catalog's motion tells.lib/motion-capture.tsandbin/gstack-motion-capture.ts: design-to-motion's deterministic capture (fake clock, whole-millisecond steps averaging 1000/60, the__start/__tick/__ltpage contract, PRE frames).lib/motion-encode.tsandbin/gstack-motion-encode: design-to-motion's ffmpeg recipes for the MP4, loop GIF and 800x500 GIF, and its seam, empty-beat, rest and overflow checks as ffmpeg PSNR comparisons.

sloplint-render.mjs, references/gates.md, scripts/fixtures/, at 7ec8682).
License text: licenses/MIT-hallmark.txt.
Derived, modified (every gate rewritten in TypeScript and in gstack's voice, mapped onto gstack's severity words; hallmark's theme stamp, genres, posture guards, photo index and judged gates are not carried over):
lib/design-lint/andbin/gstack-design-lint: the static tier's parsers (CSS rules and tokens, HTML and component pseudo-HTML, Tailwind class strings), the colour maths, the waiver record, and the rule families underlib/design-lint/rules/; the render tier inlib/design-lint/render*.ts, driving gstack's own browser instead of puppeteer.test/fixtures/design-lint/{slopped.html,eyebrow-pass,eyebrow-fail,tailwind-pass,tailwind-fail,waiver}: the fixtures, with their waiver comments rewritten to the lint's form.
DESIGN.md specification — Copyright Google LLC — Apache License 2.0
https://github.com/google-labs-code/design.md
lib/design-md.ts, bin/gstack-design-md.ts, and the Phase 6 template in
design-consultation/sections/proposal-and-preview.md.tmpl implement the
format (YAML token front matter in five groups, eight canonical sections in
spec order, {path} token references). No specification text is reproduced.
skill-diet — Copyright Nico Bailon — MIT License
https://github.com/nicobailon/skill-diet (at 5f41df1; license text: licenses/MIT-skill-diet.txt).
Adapted, not vendored: the levels table, the five-step edit ladder and the size-budget rule in
write-skill/SKILL.md.tmpl, and the full-diet procedure in write-skill/references/diet.md,
rewritten for gstack's templates, carved sections, bins and ratchet tests. The before/after/none
scoring rules in docs/designs/SKILL_EVAL_CONTRACT.md follow skill-diet's scripts/eval.mjs.
tstack — Copyright Theo Browne — MIT License
https://github.com/t3dotgg/tstack (skills/sol-loop, at 7de017b3). Ideas, not text: the
three-word severity glossary (blocker, should, nit) and the two stop rules (a review that
grew the diff cuts first; the end of the budget is not approval) in
ship/sections/review-army.md.tmpl, review/checklist.md and docs/review-policy.md
are written in gstack's words and mapped onto gstack's blocking floor. No sentence is copied,
so no license text is carried; this entry is a courtesy.
Also ideas, not text (skills/modernize, skills/leaving-pr-comments, skills/full-send,
agents/openai.yaml, at 7de017b3): the MODERNIZE / REWORK / CLOSE verdict names in
modernize/SKILL.md.tmpl, the > [!NOTE] author callout behind gstack-post --attribute, the
three-bullet unattended grant in docs/unattended.md, and a per-skill Codex default_prompt;
all written fresh in gstack's words.
Design port (skills/babysit-pr/scripts/pr-wait, at 7de017b3; license text:
licenses/MIT-tstack.txt): bin/gstack-pr-wait, lib/pr-wait.ts and
lib/pr-wait-github.ts follow pr-wait's design (one stdout line per real event,
--until green|ready|any-change, exit 0/1/2, required checks from rulesets and
classic protection, two identical polls before green, the base-moved-and-touches-
this-PR event, BEHIND and DIRTY, a per-PR lock, a 6-hour baseline), rewritten in
TypeScript on gstack's bun shebang, state root, result codes and config keys;
no Python line is carried. Each file names the source in its header.
pstack — Copyright Lauren Tan — MIT License
https://github.com/cursor/plugins (pstack/skills/interrogate, lead-judgment.md). Ideas,
not text: the lead-judgment filters applied before a merged review finding counts (nit
gravity, hypothetical versus actual, structure for a case that does not exist, a different
design is not a defect, missing context; independent agreement as the strongest signal;
NO FINDINGS as a correct result) in scripts/resolvers/review-army.ts stage 4 and
docs/review-policy.md are written in gstack's words. No sentence is copied, so no license
text is carried; this entry is a courtesy.
Also ideas, not text, from pstack/skills/blast-radius, recall, benchmark-checklist,
architect (references/design-red-flags.md) and principle-attack-the-premise
(Garry, 2026-10-26: "Do it, send"): the one safety fact, the five-rung evidence ladder and
the shared-premise red flag in investigate/sections/blast-radius.md.tmpl and
investigate/SKILL.md.tmpl; the transcript-mining fallback and its status-tagged brief in
context-restore/sections/transcripts.md.tmpl; the seven questions in
benchmark/sections/vet-the-number.md.tmpl; the second-shape comparison and the eight
design red flags in Section 1 of plan-eng-review/sections/review-sections.md.tmpl; and the generated
SKILL.md / sections/*.md files. Each section names its source in a first-line comment.
Written in gstack's words; no sentence is copied, so no license text is carried.
Also ideas, not text, from pstack/skills/principle-*, poteto-mode and its eval playbook: ETHOS.md principles 5 to 8, the observable-questions rule in plan-tune/SKILL.md.tmpl and docs/proactive.md, the blinding rules in eval-plan/SKILL.md.tmpl and docs/TESTING_INTERNALS.md, and the limiter sentence in AGENTS.md step 4 (GSTA-124).
