feat(skills): anchored-connector rule + source-traceable visuals doctrine

[WaterrrForever]

What

Two small advisory rules for the creative/animation doctrine — self-checks, not hard gates:

1. Connector lines earn their place (anti "floating gold line")

• hyperframes-creative/references/motion-principles.md § Visual Composition: any beam / rail / scan line / drawn underline must be able to name its start anchor, end anchor (real elements), and its job — reveal, route, or validate. A line the frame can lose without losing meaning gets cut. Edge-lit components usually read as more designed than free-floating arcs.
• hyperframes-animation/rules/svg-path-draw.md § Critical Constraints: same requirement at the rule level for drawn connector paths.

2. Visuals point back to the source

• hyperframes-creative/references/story-spine.md rule 4: when a video derives from concrete material (PR / repo / article / product page), each frame's key visual should trace to a specific source line — real filenames and numbers over stock props. Self-check: a prop that could appear unchanged in another product's video didn't come from the source.
• The four SKILL.md index lines that enumerate story-spine's rules are synced (creative, product-launch-video, faceless-explainer, pr-to-video). skills-manifest.json regenerated by the pre-commit hook.

Why

From a 4-cell sandbox replay comparing the official skills against the community skill geekjourneyx/hyperframes-motion-director (410★): its two strongest ideas were source-driven visual selection and mandatory anchoring for connector lines — both dimensions our doctrine didn't cover (all 357 catalog items describe how to draw; nothing covered why draw this or what a line must attach to). Ideas only — the community repo is AGPL-3.0, no upstream text or code is used; all wording here is original.

Checks

• lint:skills: 32 files, no issues
• check:skill-mirror: untouched (changes are in skills/ only, not the repo-native mirror layers)
• pre-commit (tracked-artifacts / largefiles / skills-manifest / format / commitlint): green

Reviewed at ee90f1fc (branch is current with main — ahead_by: 1, behind_by: 0, so nothing here is a base-drift artifact). No prior reviews or comments on the PR when I started, so this is a first pass, not an additive one.

Audited: all 8 changed files end to end; story-spine.md, motion-principles.md, and svg-path-draw.md in full at head; the 5 other files in skills/ that reference story-spine.md; the manifest generator (packages/cli/scripts/gen-skills-manifest.ts + src/utils/skillsManifest.ts); the Skills: manifest in sync job log; and the upstream project named in the description, for provenance.

Strengths

• Rule 4 is appended, not inserted, and that quietly matters: hyperframes-core/references/review-loop.md:11 cites story-spine § 3 by number and pr-to-video/references/story-design.md:76 cites "story-spine rule 1". Renumbering to slot the new rule anywhere but the end would have silently broken two cross-skill citations with nothing to catch it.
• Rule 4 reuses rule 3's own logic rather than introducing a parallel one — "traceable to a specific line of the source, the same way its Why traces to the message" (story-spine.md:41) hangs the new rule off the existing frame-table contract at :33. That is why it reads as doctrine and not as an added preference.
• The svg-path-draw.md:118 wording is scoped better than the creative one: "When the path is a connector (rail, beam, underline, callout) rather than a shape" exempts shape draws explicitly, which is the case that would otherwise have swallowed every logo outline draw.
• The self-checks are falsifiable, which is the hard part of writing agent-facing doctrine. "If the prop could appear unchanged in another product's video, it didn't come from the source" (story-spine.md:43) is a test an agent can actually run against its own storyboard.

Blocker

skills-manifest.json is stale at this head — the committed hashes describe content that isn't in this commit. Skills: manifest in sync is red (job log), and the description's "pre-commit (… skills-manifest …): green" claim is the opposite of what the gate reports.

I reproduced it independently rather than relaying the check — reimplementing hashSkillBundle (sorted full-path walk, .DS_Store skipped, CRLF→LF for text extensions, rel + \0 + content + \0, sha256 truncated to 16) and running it over skills/ at ee90f1fc:

skill	committed	actual at this head
faceless-explainer	c4a119451b8426a9	912f7af169c56069
hyperframes-creative	4cc3aabff6aa3214	30ef21df37d37526
pr-to-video	4ffa8a0b797eba29	8ea0227e18ab5fc6
product-launch-video	20714a2f8ab8d69b	6ebeafd86880ebb7

Byte-for-byte the same four the CI job names, and files counts are all correct. Two details worth having:

• hyperframes-animation is the one edited skill whose new hash is right (01b576293e04f72d), so the regeneration did run — it just ran before the last edit rather than after it.
• The committed values are a third state, matching neither main (1eb3772e62dd71bb, 0068574ecd376e60, 01f46da1e17577ea, d562efe00647c14b) nor this head, so an intermediate revision of those four index lines is what got hashed. The skills-manifest hook does && git add skills-manifest.json (lefthook.yml:19), so the hook isn't the gap — a commit that skipped it is the likeliest path.

Fix is the one the job prints: bun run --cwd packages/cli gen:skills-manifest, then commit.

Flagging it as a blocker rather than a nit for one specific reason: Skills: manifest in sync is not in main's required set, so nothing stops this merging red. The manifest is the published freshness fingerprint the CLI compares installed skills against, and --check only ever runs on PRs — once a stale one lands on main there is no run on the tip to go red, and it stays stale until some later PR happens to regenerate.

Important

The connector rule doesn't say which lines it governs, and read literally it cuts lines the catalog prescribes. The condition itself is checkable — "name its start anchor, its end anchor, and its job" is answerable in writing, which is what makes it usable — but the scope and the job list are both narrower than the catalog they land in. Two concrete collisions:

1. Inside motion-principles.md itself. Three bullets above the new one, the same section requires exactly what the new one cuts: :73 "Accent elements (dividers, labels, data bars)", :74 "Background is not empty. … subtle border panels, hairline rules", :77 "Use structural elements. Rules, dividers, border panels." Then :78 says "A line the frame can lose without losing meaning is decoration: cut it." A background hairline rule is precisely a line the frame can lose without losing meaning — that is the job :74 gives it. An agent has to decide on its own whether a hairline rule is a "rail", and nothing in the section tells it.

2. Across to the catalog, via underline. motion-graphics/categories/logo-reveal/module.md cites rules/svg-path-draw at :12 and lists underline_sweep as a primitive at :13 — so the same two lines pull in a rule requiring "both endpoints must sit on real elements and the draw must do a job — reveal, route, or validate" and prescribe a stroke whose job is emphasis. Same pattern elsewhere in the catalog: hyperframes-animation/blueprints/logo-assemble-lockup.md:42 ("an accent underline sweeps left→right beneath the [wordmark]") and rules/kinetic-beat-slam.md:116 ("Finale dressing — stack + accent underline sweep … don't just leave the last word sitting there").

The cheapest fix is the job list, not the scope: emphasis is a missing job, not a forbidden one. Adding it — "reveal, route, validate, or emphasize a real element" — resolves both collisions at once, since an underline is anchored to the type it sits under by construction. If you'd rather keep the list at three, then drop underline from the in-scope nouns in both files and say the rule governs lines between elements, which is what the anchoring test is really about.

Notes — checks that came back clean

• Provenance: no upstream text is reused, and I measured rather than eyeballed it. Tokenizing all 41 .md/.json/.mjs files of geekjourneyx/hyperframes-motion-director (61,357 tokens) against the four added prose blocks: zero shared 5-grams, and the single longest shared sequence is four words — "only decorates empty space" — which matches the snake_case identifier path_only_decorates_empty_space in MOTION_PRIMITIVES.template.json:49, not prose. Only four content-word 3-grams overlap in total. CJK content upstream is ~1k characters, confined to eval prompts, so the English measurement covers essentially the whole corpus. "No upstream text or code is used; all wording here is original" holds.
• Worth stating plainly for the record, since it is the part a measurement alone doesn't settle: the checklist scaffold is recognisably adopted. SKILL.md:240-247 upstream reads "Before keeping any connector, name: — Start anchor … — End anchor … — Job: reveal, route, compare, focus, validate, hand off, or close … — Deletion test: what meaning … is lost if it is removed." The new bullet asks for start anchor, end anchor, and job, then applies a deletion test, with a job list that is a subset of theirs. That is idea-level reuse rather than expression — no protected sentence survives, and AGPL reaches the code and text, not the concept — so I don't read this as an attribution obligation, and crediting the project by name in the PR description is the right place for it. (Incidentally, "focus" is one of the four upstream jobs the subset drops, and it is exactly the one the emphasis-underline case above needs.)
• The "four SKILL.md index lines" claim is complete. Five other files in skills/ reference story-spine.md and none of them enumerates the rule list: general-video/SKILL.md:94,104 and the three workflow references/story-design.md files cite it by topic, and review-loop.md:11 cites § 3. Nothing else needs syncing.
• Nothing load-bearing is hidden in the 80 deletions. Normalising whitespace and table padding, 67 of the 80 removed lines reappear identically as additions; the 13 that actually changed are the ones the description names — 5 manifest hashes, the "three → four" intro line, and 7 index-description edits across the four SKILL.md files. The deletion count is prettier reflowing three tables after one cell got longer.
• CI, stated as two separate claims because they disagree: all 8 required contexts reported — Semantic PR title and regression green, the other six skipped by the path filter — so mergeStateStatus: BLOCKED here is the reviewer gate (reviewDecision: REVIEW_REQUIRED, no approvals), not CI. Separately, the one gate with real signal on a skills-only change is the red one, and it isn't in the required set.

Nit

svg-path-draw.md:118 is an editorial constraint sitting in a list of four mechanical ones (fill: none, dasharray = getTotalLength(), overestimate on complex paths, stagger at 70–80%). Everything else under Critical Constraints breaks the animation if you get it wrong; this one produces a worse-looking frame. Not worth moving on its own, but if the section ever grows a second judgment call, they'd read better grouped.

Verdict

Verdict: REQUEST CHANGES
Reasoning: The doctrine is sound and both rules are the kind that survive contact with an agent, but the PR ships a generated artifact that contradicts its own content — verified independently, not just relayed from CI — and the check that catches it is not required, so nothing prevents it merging stale. Regenerate the manifest and I'll re-review; the connector-scope item is a wording call I'd like addressed in the same push but would not hold the PR for on its own. I have not merged anything.
