blogosphere cuts its first release behind a signed macOS build pipeline, superpowers and superpowers-chrome each ship a point release, and evener picks up an outside contributor's code-signing work

Week of September 21, 2026 · Sep 21, 2026–Sep 27, 2026 · published Sep 25, 2026

Three repos shipped tagged releases this week: obra/blogosphere cuts v0.1.0, its first release ever, behind a from-scratch signed-and-notarized macOS build pipeline; obra/superpowers ships v6.4.2; and obra/superpowers-chrome ships v3.0.6. Underneath them, prime-radiant-inc/evener has its busiest week by commit count, and picks up a handful of commits from an outside contributor doing macOS code-signing CI work. This week is still open: the data below runs through Friday evening, not the full calendar week.

obra/blogosphere

Local-first, multi-platform blogging client for an 11ty blog that lives in a GitHub repo — the repo is the database.

144 commits 🏷 v0.1.0 +18,147 −2,984

Its first tagged release, v0.1.0, behind a from-scratch signed-and-notarized macOS release workflow: a Developer ID identity imported and matched against the configured signing identity, a .dmg build that gets stapled and verified, pinned actions with no saved token, and the release gated to run only on tagged commits on main after checks pass. Alongside the release infrastructure: a nightly-fuzz timeout fix for async property tests that were outlasting the default limit, and a string of UI polish items — an activity-popover arrow that now points at the sync button’s center, syntax colors fixed to a readable accent-independent blue, draft/publish toolbar copy, and markdown line alignment fixes. Sole author: Jesse Vincent (staff).

obra/superpowers

An agentic skills framework & software development methodology that works.

1 commit 4 PRs 🏷 v6.4.2 +61 −85

Tagged release v6.4.2, “leaner plans from writing-plans” — a rewrite of the writing-plans skill’s core philosophy: a plan is decisions, not a transcript, built around a step recipe, a proportion check, and an assumption that the reader is capable. Still mostly invisible to the commit-count column above — its work lands on a dev branch, not main, which is the only branch this blog’s tooling walks for commits; the merged-PR count is the reliable signal here. By merged PR: sole author Jesse Vincent (staff).

obra/superpowers-chrome

Claude Code plugin for direct Chrome browser control via DevTools Protocol — zero dependencies.

1 commit 1 PR 🏷 v3.0.6 +1,146 −43

Tagged release v3.0.6, “Secret-safe auto-capture”: a fix so the plugin never auto-captures or echoes credential-shaped page content. Sole author: Jesse Vincent (staff).

Also shipped

prime-radiant-inc/evener

A coding agent: give it a prompt and it reads, writes, runs commands, and searches code in a loop until the work is done, using native tool-calling across OpenAI, Anthropic, and Google models.

185 commits 180 PRs +293,329 −51,818

Its busiest repo of the week by commit count, in a partial (Monday–Friday) window: deep native/web refactor work — a pending-turn commit feed and stall tripwire moved into the shared package, a mutation-projection fence unified across web and native, idle-release members torn down in bounded depth waves — alongside a run of test-suite modernization (dropping fake-toolchain and npm-shim tests, porting the web and browser gates to Go) and fixes to raw-argument display, doctor audit-selector collisions, and legacy-named project-bucket lookup. Separately, macOS release-signing infrastructure work landed: importing a Developer ID identity, matching the configured signing identity, and signing and notarizing release artifacts. Contributors: Jesse Vincent (staff), nearly all of it, plus jtdaugh (outside), who did the signing/notarization CI work.

prime-radiant-inc/terminal-bench-analysis

Fetches detailed JSON results from the Terminal Bench 2 leaderboard, loads them into SQLite, and publishes queryable analysis via Datasette.

2 commits 1 PR +472 −448

One security fix: a leaked Claude OAuth token redacted from a committed result.json, plus hardening of fetch_data.py against the same class of leak recurring. Landed via a scheduled github-actions[bot] fetch commit (automated, not a contributor) and a human follow-up fix from Ada Sen (staff).

prime-radiant-inc/shipped

A weekly log of what Prime Radiant and obra shipped (this repo).

4 commits 1 PR +4,263 −6

Merged the weeks-of-2026-09-07-and-2026-09-14 posts, plus the outside-contribution-count and attribution corrections that followed them. Sole author: Ada Sen (staff).

obra/lace

Lightweight agentic coding environment.

9 commits 9 PRs +3,054 −210

A provider/catalog-heavy week: LunaRoute catalog limits fixed and max output fit to the context window, claude-opus-5-5 added to the static Anthropic catalog, Responses-API tool-output ordering and stateless coverage fixed, a finished delegate’s container now released properly on job_kill, persona connectionId frontmatter and a query() connection override added, and a deepseek-4.1-flash-background catalog entry added. Contributors: Jesse Vincent (staff), the large majority, and Ada Sen (staff), one commit.

obra/scan-to-model

Evidence-driven scan reconstruction skills and local tools for Codex and Blender (new two weeks ago).

11 commits +4,005 −95

Continued build-out: recognizable room features reviewed against source photographs, extracted captures accepted through an intake command, reconstructions grounded in coverage with full deliveries preserved, source tracking simplified to preserved originals and source IDs, and packed native, still-tour, and offline-viewer delivery formats added. Sole author: Jesse Vincent (staff).

The remaining active repo — claude-plugin-stats — had only bot-driven activity again this week (five days of the daily install-stats scrape and chart rebuild), with no human commits.
