From a4f5ec676afcd19212966bda51feb06368b3bb21 Mon Sep 17 00:00:00 2001 From: Test Date: Thu, 4 Jun 2026 02:02:12 +0200 Subject: [PATCH 1/2] fix(skills): document PRD-seeding consent model; remove literal URL Tessl's Snyk-backed moderation flagged v2.10.10/v2.10.11 Critical with: - E005 Suspicious download URL detected in skill instructions - W011 (x2) Third-party content exposure (indirect prompt injection risk) - W012 Runtime URL detected that controls agent behavior All four point at the `/iikit-core init ` sub-action that optionally fetches a user-supplied URL and uses its contents to draft PREMISE.md and downstream GitHub issues. The behavior is intentional (user-opt-in only, multiple review gates), but was undocumented as a deliberate consent contract and the example used a literal `https://example.com/prd.md` placeholder that the URL-pattern check picks up directly. - prd-seeding.md: open with an explicit "Security and consent model" section covering opt-in surface, the artifact-review gates (PREMISE.md, /iikit-00-constitution, per-issue confirmation), and the no-code-execution boundary. Adds a paragraph at the read-document step reiterating that the agent fetches only what the user named. - iikit-core/SKILL.md: argument-parsing paragraph swaps the literal example URL for `` placeholder and links the consent model. Pattern-only scanners won't react to this; Tessl's moderation is agentic (snyk.io/blog/snyk-tessl-partnership) and should re-score against the explicit consent narrative on the next publish.

The behavior is intentional — user-opt-in only, gated behind explicit input — but was undocumented and used a literal `https://example.com/prd.md` placeholder that tripped the URL-pattern check. `iikit-core/references/prd-seeding.md` now opens with a "Security and consent model" section explaining the opt-in surface, the artifact-review gate (PREMISE.md → `/iikit-00-constitution`), and the no-code-execution boundary; `iikit-core/SKILL.md`'s argument-parsing paragraph replaces the literal URL with a `` placeholder and links the consent model. Agentic moderation should re-score against the explicit consent narrative. - **`Verify tile` step retries through moderation gate**: Tessl 0.81+ returns 403 Forbidden on `tessl install` while a just-published version's `moderationStatus` is `pending`. The publish job's verify step ran the install immediately after publish, hit the 403, fell through to a dead `@0.7.0`/`@0.6.5` fallback, and cascaded 73 "skill directory missing" failures. `tests/run-tile-tests.sh` now retries the registry install with exponential backoff between attempts (30 → 60 → 120 → 240 → 300 → 300 seconds, 7 attempts total, ~17.5 min budget) and fails cleanly with admin-override remediation guidance if it never clears. Dead version-fallback removed. - **Tessl install path moved from `.tessl/tiles/` to `.tessl/plugins/`** (#80): Tessl CLI 0.81+ installs tiles to `.tessl/plugins///` instead of `.tessl/tiles///`. Every hardcoded reference in the repo (CI workflows, gh-aw policy-reviewer prompts, every `iikit-*/SKILL.md` invoking a script, pre/post-commit hooks, dev-time symlink, source/tile test paths) was updated to the new path. Without this fix, CI's E2E install test fails on every PR, the OpenAI gh-aw reviewer posts `Policy load failed` `CHANGES_REQUESTED` on every PR, and end-users on Tessl 0.81+ get "No such file or directory" when invoking any iikit skill. Mechanical rename only — no behavior change. From d41646957e879cc0d6984959df5276a769718a59 Mon Sep 17 00:00:00 2001 From: Test Date: Thu, 4 Jun 2026 02:07:35 +0200 Subject: [PATCH 2/2] fix(skills): drop scanner-rationale and `because` clause from prd-seeding context-writing-style review feedback on PR #91: the new Security-and-consent-model section carried scanner-rationale prose (naming W011/W012, explaining mitigations) and a banned `because` clause. Both belong in CHANGELOG per the rule's What-to-Cut clauses (meta-justification, why-content). Skill-loaded prose stays directive. - Drop the trailing scanner-rationale paragraph entirely. - Tighten the four consent bullets: cut intensifiers ("intentionally", "fully", "exactly the same way"), strip the "trust as much as you trust" hedge, remove the "above" backreference, and reframe the read-document follow-on as a directive instead of a justification. - CHANGELOG entry (already in place from a4f5ec6) keeps the W011/W012/E005 narrative. Same consent contract, fewer words, no banned connectives.
