 * [x] Prepared clean workspace at `./work/main`: fetched all refs, checked out `main`, and reset hard to `origin/main` to ensure a pristine base for feature branches.
 * [x] Create a machine-readable PR plan (once): generate docs/PR_PLAN.md enumerating PR order and branch names; sections in this exact order to minimize conflicts: (1) Repo scaffolding & hygiene, (2) Core CLI & client, (3) Tool manifest & runner, (4) Tool-call loop & validator, (5) Baseline docs/ADR/diagrams, (6) Each tool (one PR per tool), (7) Tests per component, (8) Makefile, scripts, and CI gates, (9) Security & runbooks, (10) Research tools (one PR per tool), (11) Remaining docs and examples; commit this plan on a short-lived planning branch: `git switch -c pr/plan && mkdir -p docs && printf "...ordered list with branch names..." > docs/PR_PLAN.md && git add docs/PR_PLAN.md && git commit -m "PR plan: ordered slicing from develop to main" && git push -u origin pr/plan && gh pr create --base main --head pr/plan --title "PR plan: ordered slicing" --body "Adds docs/PR_PLAN.md to drive small PR slicing" --draft`; Definition of Done: a draft PR to main exists containing docs/PR_PLAN.md with the full ordered plan — OPEN: https://github.com/hyperifyio/goagent/pull/6

 * [ ] Slice PR #02 — minimal CLI entrypoint (compile-only, no HTTP/tools): `git switch -c pr/02-cli-main main && git restore --source develop --staged --worktree cmd/agentcli/main.go && git restore --source develop --staged --worktree cmd/agentcli/go.* || true && go build ./cmd/agentcli`; update README usage snippet minimally if referenced by main.go; commit/push/create PR; Definition of Done: `go build ./cmd/agentcli` succeeds on a clean checkout of the branch; PR contains only cmd/agentcli/* (and any edited README lines).

 * [ ] Slice PR #03 — flags & help (no network): `git switch -c pr/03-flags-help main && git restore --source develop --staged --worktree cmd/agentcli/flags.go cmd/agentcli/usage_test.go docs/reference/cli-reference.md`; run `go test ./cmd/agentcli -run Help -v` (or the repo’s equivalent); commit/push/PR; Definition of Done: `agentcli --help` works locally (prints full usage), tests covering help/flags pass, only flags/help related files changed.
