ci: bound Discord issue announcement formatting by Daxiongmao87 · Pull Request #183 · Daxiongmao87/simulacrum-foundry

Daxiongmao87 · 2026-07-17T22:11:41Z

Summary

Move Discord payload construction out of the workflow's embedded jq parser and into a 250-line, dependency-free ES module.
Preserve paragraph and list boundaries, leading indentation, complete indented-code lines, and simple top-level backtick fences.
Convert ordinary ATX headings to Discord-safe bold labels while retaining explicit heading provenance; authored bold paragraphs and heading-like code indented by spaces, tabs, or spaced tabs remain unchanged.
Bound descriptions to 700 Unicode code points by retaining complete blocks; skip leading generated headings when applying the oversized-prose word fallback.
Bound titles to 256 Unicode code points without splitting astral characters.
Keep empty-body fallback, issue metadata, mention suppression, and webhook delivery behavior.

Deliberate scope boundary

This is a bounded announcement formatter, not a CommonMark/GFM parser. It does not parse or repair inline emphasis, inline-code delimiter runs, links, reference links, GFM tilde fences, or nested blockquote/list fence containers. Unsupported constructs remain ordinary normalized text. This removes the duplicated parser state machines that expanded the workflow to 1,431 lines.

Final maintainability limits:

44  .github/workflows/announce-new-issue.yml
250 .github/scripts/build-issue-announcement.mjs
270 tests/regression/announce-new-issue-payload.test.mjs

Related work

Uses the body of feat: add bounded read-only subagents as a delegation tool #181 as the representative announcement fixture.
Simplifies the formatting follow-up introduced by ci: announce new issues in Discord #179.

Empirical Verification (UTRs)

Focused payload regression

$ node --test tests/regression/announce-new-issue-payload.test.mjs
✔ issue 181 keeps readable complete sections within the Discord limit
✔ empty bodies retain fallback metadata and disable mentions
✔ line ending and prose normalization preserve paragraph boundaries
✔ lists retain line boundaries and leading indentation
✔ supported code blocks preserve whitespace and heading-like content
✔ unsupported tilde fences remain ordinary normalized text
✔ truncation keeps complete blocks and drops a dangling heading and fence
✔ word fallback skips generated headings and retains oversized prose
✔ truncation preserves authored standalone bold paragraphs
✔ an oversized first block truncates on a complete word
✔ description bounds count Unicode code points without splitting astral text
✔ bounded formatting leaves inline Markdown semantics untouched
✔ oversized titles retain the Discord title limit
✔ title bounds count Unicode code points without splitting astral text
✔ command line entry point writes the workflow payload

Formatting

$ npx prettier --check .github/workflows/announce-new-issue.yml .github/scripts/build-issue-announcement.mjs tests/regression/announce-new-issue-payload.test.mjs tests/regression/fixtures/issue-181-body.md
Prettier: all files formatted

Generated payload smoke check

Description begins: "**Summary**\n\nAllow the primary Simulacrum agent to delegate multiple independent"
Description code points: 634
Ends with complete-block ellipsis: PASS
Supported backtick fences balanced: PASS
Emoji description code points: 700 WELL_FORMED
Emoji title code points: 256 WELL_FORMED
Leading-heading prose fallback: PASS
Indented trailing whitespace: PASS
Spaced-tab code: PASS
Mentions disabled: {"parse":[]}
Live Discord request: not sent
Generation time: 0.036s

Security invariants

Workflow permission is limited to contents: read for checkout.
Checkout uses persist-credentials: false.
Discord mentions remain disabled through allowed_mentions: { parse: [] }.
The webhook URL continues to come exclusively from DISCORD_ISSUE_WEBHOOK_URL.
