Dogfood Proof: Single-Prompt Store-Scoped Change

Slice 1.4 acceptance evidence (spec scenario "Single-Prompt Store-Scoped Change"). Run 2026-06-11 against the built CLI at commit d2b62cc (plus the checkpoint-4 test work in progress).

Arrangement

• Scratch project repo /tmp/openspec-dogfood-14/app-repo (git-inited), prepared with openspec init . --tools claude --profile core — so the repo has its own local OpenSpec root and the five generated core workflow skills under .claude/skills/.
• Isolated machine state: XDG_DATA_HOME/XDG_CONFIG_HOME pointed at scratch dirs; OPENSPEC_TELEMETRY=0; openspec on PATH via a shim to the repo's built bin/openspec.js.
• Store: openspec store setup team-context --path /tmp/openspec-dogfood-14/team-context (Git on by default, initial commit created), registered in the isolated state.

The prompt (verbatim, the only instruction given)

Create a change in our team store for reworking billing invoicing. Just
create the change itself, no need to write the artifacts yet.

No ids, paths, or flags. The store is named only in words ("our team store").

Invocation: claude -p "<prompt>" --dangerously-skip-permissions --max-turns 25 --output-format text, cwd = the app repo.

What the agent did (tool calls, from the session log)

TOOL Bash: openspec --help 2>&1 | head -50
TOOL Bash: ls -la /private/tmp/openspec-dogfood-14/app-repo
TOOL Bash: openspec store --help 2>&1; echo "---"; openspec store list 2>&1
TOOL Bash: openspec new --help 2>&1; echo "---"; openspec change --help 2>&1
TOOL Bash: openspec new change --help 2>&1
TOOL Bash: openspec new change rework-billing-invoicing --store team-context --description "Rework billing invoicing" 2>&1

Six tool calls: top-level help → store group help + store list (discovered team-context) → command help → one store-scoped creation. No initiative or workspace command was invoked at any point.

The agent's final message

Done. I created the change rework-billing-invoicing in the team-context store at /private/tmp/openspec-dogfood-14/team-context/openspec/changes/rework-billing-invoicing/, using the default spec-driven schema with the description "Rework billing invoicing".

No artifacts (proposal, design, specs, tasks) have been written yet, per your request. When you're ready to flesh it out, you can run openspec status --change rework-billing-invoicing --store team-context to see the artifact checklist, or ask me to generate the artifacts.

Note the agent's own follow-up suggestion carries --store team-context — the hint-continuity contract from slice 1.3 surviving into agent behavior.

End-state assertions (verified on disk)

• team-context/openspec/changes/ contains rework-billing-invoicing/ (plus archive/). ✓
• The app repo's local openspec/changes/ contains no change — the local root was not misused despite being the nearest root. ✓
• No initiatives/ directory in the store; the isolated XDG_DATA_HOME/openspec/ contains only stores/ (registry). ✓

Verdict: pass. A fresh headless agent session, given one plain prompt and only the generated guidance plus --help output, discovered the registered store and completed a store-scoped change without hand-holding.
