Switches every call site to `node scripts/newsletter` and, in the same pass,
fixes three structural problems in the skill layer.
The seven subcommands were spelled out in five files; they are now enumerated
once in docs/newsletter/engine-commands.md, and every other mention is a link
except where a skill inlines the one or two commands it actually invokes. The
shared post mechanics move out of mt-add-url's directory into docs/newsletter/,
so no skill owns another skill's documentation and both runtimes reach it by a
repository-relative path. The Codex adapters become symlinks to their canonical
counterparts, which removes the parallel frontmatter that could drift.
Two skills are renamed for a uniform mt-<verb>-<object> scheme: mt-add-post
becomes mt-add-article, since it adds an article to a post, and mt-webfetch
becomes mt-fetch-url. The other four already conformed. Note that $mt-add-post
and mt-webfetch no longer resolve; no alias directories are left behind, because
two names for one skill is the duplication this change removes.
Trigger wording in the frontmatter descriptions is left alone apart from the
renamed tokens and the corrected fetch-tier summary: those strings are how the
runtimes decide whether to invoke a skill.
Setup documentation now states the npm ci prerequisite. The engine has
dependencies, so unlike its predecessor it does not run on a bare clone.
Add a reader-proxy tier after defuddle, stop skipping URLs that only fail a
plain classifier fetch, let a session pin an earlier draft as the target post,
and tighten Substack image candidate handling (dedupe, stable numbering,
reuse a resolved source post across a batch).
One Go binary with a subcommand per former script, invoked as
'go run ./scripts/newsletter <command>' from repo root. Stdlib only;
publications config embedded via go:embed (go run recompiles on edit).
Behavior parity verified side-by-side before deleting the JS —
see plans/reports/parity-260818-newsletter-go-migration-report.md.
Permissions: allow 'Bash(go *)', drop 'Bash(node *)' and the redundant
'Write(content)' rule (Edit rules cover all file-editing tools).
Extract newsletter scripts to a neutral scripts/newsletter/ engine and add
side-by-side support for all three AI coding tools off one source of truth.
- Move 9 scripts + substack config from .claude/skills/**/scripts to
scripts/newsletter/ (history preserved); fix PROJECT_ROOT depth and
cross-require/config paths; repoint all SKILL.md invocations
- Add canonical AGENTS.md; reduce CLAUDE.md to an @AGENTS.md import
- Add opencode.json (permissions, no MCP); skills auto-discovered in place
- Add codex/prompts/*.md (6 prompts) + copy installers (install.sh/.ps1)
- Add docs/multi-tool-usage.md (setup, per-tool invocation, teardown) + README pointer
- fix checkDuplicate false-negative on Substack cover images (uuid with no size suffix)
- stop cleanUrl from corrupting the query string on unparseable input
- extract shared fetchWithTimeout into url-utils (consistent timer cleanup)
- split find-substack-post html/rss helpers into html-text-utils
- scan content/post for duplicates, matching the other scripts
- correct doc drift in mt-add-image/mt-add-url and drop plan-phase code comment
Add the image handler in the meta-dispatch architecture. Given an image
URL it resolves a label and inserts it into the newsletter Bonus -> Images.
For Substack-hosted images, decode the S3 image UUID and find the source
post across configured publications (ByteByteGo by default): RSS feed first,
then a sitemap crawl up to ~3 months back. Label priority is figure caption,
then post title, then a user-typed name. Non-Substack images are best-effort
then ask. Publications are configurable and the skill offers to add a new one
when the user identifies it.
Wire mt-add-url to dispatch the image route to mt-add-image (previously a
fallback). Update the project skills list.
Add mt-add-url meta skill that classifies a URL and auto-dispatches to a
handler skill: articles to mt-add-post, YouTube links to the new
mt-add-video (Bonus -> Videos with a Vietnamese title + short summary).
Unsupported types (image, etc.) prompt the user to add or extend a skill;
image support is deferred to a future mt-add-image handler.
Shared logic (add-url.js router, url-utils.js, find-newsletter-number.js)
and a shared post-mechanics reference live under mt-add-url/. mt-add-post
is reduced to an article-only handler. add-url.js detects watch/youtu.be/
shorts, normalizes to the canonical watch URL, dedups by video id, and
fetches the title via oEmbed. checkDuplicate uses execFileSync (no shell).
