162-251:⚠️ Potential issue | 🟠 MajorIncomplete fix: example diagrams below the directive still use Unicode box-drawing characters.
The new directive at lines 72–77 forbids
┌,─,│,▼,═, etc., but the three example diagrams further down in the same template still use them:
- Lines 162–176 (
COLLABORATION SPECTRUM):═,│,▼,┌,─,┐,└,┘- Lines 185–205 (
CURRENT AUTH FLOW):┌,─,┐,│,▼,└,┘,┬,┴- Lines 237–251 (
CLI TOOL DATA STORAGE):┌,─,┐,└,┘This contradicts the directive and will likely cause the LLM to mimic these Unicode patterns, reproducing the exact ambiguous-width visual artifact described in
#983that this PR claims to close. The OPSX command template (lines 303–482) was already cleaned up because it doesn't contain these examples — but the skill template still does.Please convert these three diagrams to ASCII-only as well (using
+,-,|,v,^,-->) so the examples match the directive.♻️ Suggested ASCII conversion for the three example diagrams

This fixes the issue of ambiguous unicode character width when visualizing on terminals
Rebase onto main and close the gaps in the original fix: - Regenerate skills/openspec-explore/SKILL.md. The static skills/ mirror landed after this branch was cut, so the parity test would have failed with the template and the mirror out of sync. - Regenerate the three parity hashes through scripts/regen-parity-hashes.mjs. - Convert the ambiguous-width glyphs the first pass missed: the bullets in the CLI-storage example, and the check/cross marks in its comparison table, which sat in the column-aligned block the bug is about. - Tighten the ASCII guidance to two lines. It ships into every user project on both delivery surfaces, so the paragraph was pure overhead. - Add regression tests (Fission-AI#983): every fenced example in both the skill and the command body must be free of box-drawing, arrow, bullet, and check/cross glyphs, and the guidance must state the rule and the reason. - Add a patch changeset.

Status
LGTM for final review. The branch is hardened on top of #1716, generated output is in parity, and every CI/security/platform check passes.
What was wrong
Explore's worked diagrams used Unicode box-drawing, arrow, bullet, and marker characters. Their display width varies across terminals, fonts, and locales, so copied padded layouts could drift. The original regression guard covered only selected Unicode ranges and could miss other non-ASCII diagram characters.
How it was fixed
All worked diagrams now use plain ASCII. The guard checks every character inside every fenced example and rejects any byte outside ASCII. The explanation now accurately describes cross-environment width variation instead of classifying every removed glyph as East Asian Ambiguous Width.
This branch also includes #1716's confirmed-write contract so regenerating the shared Explore template cannot weaken it: read-only investigation needs no confirmation, write-capable actions must name their scope and receive a separate yes/no confirmation, and scope expansion requires confirmation again. Merge #1716 before this PR.
Replication / proof
test/core/templates/explore.test.ts: 16/16 passed.test/core/templates/skill-templates-parity.test.ts: 26/26 passed.skills/openspec-explore/SKILL.mdand all parity hashes were regenerated from source.Notes / nits
Inline Unicode prose outside diagram fences is intentionally unchanged. This PR fixes diagram alignment without imposing an ASCII-only rule on normal text.
Closes #983
