Hands-off, diff-scoped browser QA of the active branch: maps user flows, drives a real browser, autonomously fixes small breakages with regression tests and commits, judges experience against product personas, and writes a durable dogfood report. Manual invocation only.

Dogfood Act as a QA engineer who dogfoods the active branch end to end, autonomously, until it is genuinely ready. Outcome: every user visible change this branch introduced has been driven in a real browser along its whole journey, judged for correctness and for how it feels to the product's personas, with small breakages fixed, regression tested, and committed. Done: every matrix scenario is Pass , Fixed , Skipped , or in a terminal Blocked state; the project's automated suite has been run once and its result recorded; and the report at <root /dogfood reports/<YYYY MM DD <branch slug dogfood.md is finalized against its template and committed. A green matrix over a red suite finalizes as a not ready verdict rather than a ready one. Chasing that suite green is not this run's job. This is diff scoped , not whole app exploration. You test what this branch introduced or modified versus the trunk. Read references/phases.md before Phase 0 (Scope) and follow it. It defines every phase in detail; the run cannot be executed correctly from the phase list below. Boundaries Drive the browser exclusively through the agent browser CLI — never Chrome MCP tools ( mcp claude in chrome ), another browser MCP, or a built in browser control tool, even when the platform offers one. Use the direct binary, never npx agent browser (the direct binary uses the fast Rust client). Never dogfood the trunk on a branch name or blank target — there is no diff. A PR target always has a base, so it is always diffable even when its head branch is named main . A numeric target stays a PR identity through isolation and checkout — never collapse it to its head ref, whose name may itself be main . Never switch the primary checkout out from under the user. This skill decides only whether to offer isolation — no for a blank or current branch target (you are already on it), yes for a PR or another named ref — and ce worktree handles the mechanics and reports the verdict. On a declined offer, check the target out in place, confirming first if uncommitted changes would be disturbed. Screenshots and other transient artifacts go to OS temp ( mktemp d "${TMPDIR: /tmp}/ce dogfood XXXXXX" ), never the repo root; copy one in only to embed it in the report. Auto fix only what is small, well understood, and low risk. A change that needs an architectural or schema decision, alters product behavior or UX intent, spans many files, or has plausible competing solutions is escalated to the report's Decisions for a human section, never implemented to clear a matrix item. Prerequisites User runnable invocation rendering. In prerequisite failures, default to /ce setup and /ce dogfood <original arguments ; use $ce setup and $ce dogfood <original arguments only when the active host is Codex or explicitly documents dollar prefixed skill invocation. On oh my pi ( omp ), use /skill:ce setup and /skill:ce dogfood <original arguments . Render only each invocation as inline code and output one form only. A local dev server you can start ( bin/dev , rails server , npm run dev , etc.). agent browser installed. Check: If not installed, stop and tell the user to install agent browser : print the rendered ce setup invocation for the current install command, followed by the rendered ce dogfood <original arguments invocation to retry. This workflow cannot function without it. Artifact Root Reports live under <root /dogfood reports/ and personas under <root /personas/ . Resolve <root the first time you compose any <root / path, whether you are reading or writing, and never before. A run that composes none skips it. <! ce docs root:start Resolve the CE artifact root <root before composing any artifact path. Read docs root from <repo root /.compound engineering/config.yaml only ( <repo root = git rev parse show toplevel ). Do not read it from config.local.yaml . Unset <root is docs , exactly as before. Validate a set value: a repo relative directory whose real, symlink resolved path stays inside the repo and is neither the repo root nor under .git/ . Otherwise stop with an error naming docs root and the value never fall back to docs . Use <root as the sole artifact location: create it if absent, compose each path as <root /<subdir with this skill's own subdirectory, and never also read docs . <! ce docs root:end Delegation ce dogfood is an orchestrator: prefer an existing CE skill over re deriving its behavior. Isolate a PR or named branch target with ce worktree ; take a non obvious root cause to ce debug ; commit each fix with ce commit ; capture a reusable lesson with ce compound . Compound Packs The repo's declared Compound Packs supply personas and criteria. A pack rule that describes a user is a persona the flows are walked as; one that prescribes how the product must look or behave is a criterion each scenario it reaches is judged against, and a contradiction is a failure that enters the fix loop with its (pack: <id , <path within the pack ) citation. A contradiction the branch intends is a decision for a human about the rule, not a fix. Judgments that generalize go back to the packs through ce compound ; this skill never writes a pack. references/phases.md defines how packs are applied. Phase order Scope analyze the diff map the flows derive the matrix serve execute fix loop report. The order is the invariant: the flow model precedes the matrix, and the matrix precedes any browser work. Each phase's conditions are in references/phases.md ; read it before Phase 0 (Scope) rather than reconstructing a phase from this line. Work one scenario at a time, judged for correctness and for how it feels to each persona. A fix is not done until a regression test fails before it and passes after, or the report says why no automated test was meaningful. Checkpoint, not a final write. Create the report from references/dogfood report template.md as soon as the matrix exists, with every scenario at Pending , and update it after each scenario is judged and each fix is committed. <branch slug is the branch name lowercased, with every run of non alphanumeric characters — slashes included — collapsed to one . Find a prior run by globbing <root /dogfood reports/ <branch slug dogfood.md . The task list is session scoped, but the report on disk is what a later run or a teammate resumes from, so an interrupted run must leave a template shaped checkpoint rather than a bare matrix. Terminal states. Blocked (needs human verify) (a step that needs an outside interaction, such as OAuth, real email, payments, or SMS, and cannot be driven headlessly) and Blocked (human decision) (a fix too big to make autonomously) both wait on a person, and each ends that scenario, not the run: continue the rest of the matrix, and never silently re queue a blocked scenario, on this run or on resume. How a person is reached differs per state, and the phase that sets the state says which.
