---

- **added** — Devin CLI support to install superpowers via `devin plugins install obra/superpowers` with skills auto-triggering at session start
- **added** — Hermes Agent support to install from git clone with skills registering to Hermes' native loader and bootstrap loading on first turn
- **added** — Grok Build CLI added to install documentation
- **changed** — Ceremony now scales to the task by classifying requests as spike, bounded, or architectural, with small tasks skipping the two-document ritual
- **changed** — Controllers no longer stall on plan conflicts; non-catastrophic conflicts get a recorded ruling and work continues while only destructive or irreversible actions stop for human approval
- **changed** — Pre-dispatch conflict scan records its checks in the ledger instead of just asserting the plan is clean
- **changed** — Small same-shape tasks batch into one dispatch, cutting subagent cost on micro-task plans
- **changed** — Implementers and reviewers may not spawn their own subagents to prevent duplicate reviews
- **changed** — Plans carry a Spec pointer and SDD reads the spec at setup so plan conflicts get resolved against the design
- **changed** — Reviewers re-read evidence they find illegible instead of re-running the test suite
- **changed** — Subagent waits are event-driven instead of poll-heavy, spawn pin model and reasoning effort explicitly
- **changed** — Worktree removal no longer destroys untracked files; when git worktree remove refuses due to uncommitted work, the skill stops and asks instead of using force
- **fixed** — render-graphs.js in writing-skills now works on Windows
- **fixed** — Corrected Copilot CLI backgrounding guidance for Windows
- **fixed** — bump-version.sh now covers the Hermes manifest
- **changed** — README reorganized with added table of contents and restructured Getting Started section

###### Harness Support

- **Devin CLI**: `devin plugins install obra/superpowers` now works, and skills auto-trigger at session start. (#1995)
- **Hermes Agent**: install from a git clone; skills register with Hermes' native loader and the bootstrap loads on the first turn. (#1922, #2025)
- **Grok Build CLI** added to the install docs. (#1919)

###### Brainstorming

- **Ceremony now scales to the task.** Requests are classified as spike, bounded, or architectural; small tasks skip the two-document ritual. Every path still stops for your approval before implementation. (#2063)

###### Subagent-Driven Development

- **Controllers no longer stall on plan conflicts.** Non-catastrophic conflicts and ambiguities get a recorded ruling and work continues; only destructive or irreversible actions still stop for a human. One donated session had sat blocked for almost nine hours on a question the controller could have decided. (#2077)
- **The pre-dispatch conflict scan records its checks in the ledger** instead of just asserting the plan is clean. (#2080)
- **Small same-shape tasks batch into one dispatch**, cutting subagent cost sharply on micro-task plans; batch reviews verify every file in the brief made it into the diff. (#2078)
- **Implementers and reviewers may not spawn their own subagents**, which was producing duplicate reviews. (#2059)
- **Plans carry a `Spec:` pointer** and SDD reads the spec at setup, so plan conflicts get resolved against the design instead of guessed at. (#2086)
- Reviewers re-read evidence they find illegible instead of re-running the test suite (#2089), and circuit-breaker rulings now show up in the Finish report.

###### Codex

- Subagent waits are event-driven instead of poll-heavy, spawns pin model and reasoning effort explicitly, and the multi-agent reference is corrected against Codex source. (#2060, #2061, #2062)

###### Finishing a Development Branch

- **Worktree removal no longer destroys untracked files.** When `git worktree remove` refuses because the tree holds uncommitted work, the skill stops, names the files, and asks — instead of reaching for `--force`. (#2016, #1223, #2024)

###### Fixes

- `render-graphs.js` in writing-skills works on Windows.
- Corrected Copilot CLI backgrounding guidance for Windows. (#1929, #2006)
- `bump-version.sh` covers the Hermes manifest.

###### Documentation

- README: added a table of contents and reorganized Getting Started.
