steps is string[] and the engine pipes each entry to sh -c. Prose is accepted, then fails at runtime:
code
plan v1.0.1, execution c2fc8d90:
step "Check df -h and df -i on adam-slave-0 /home"
→ sh: line 1: Check: command not found (exit 127)
Meanwhile the working runs used step ids (diag-slave0-before, confirm-nested-tree, report-abort) that were not in the plan schema at all. The agent and the engine invented them.
Missing from the schema:
Validation is also unhelpful. create_plan rejected my steps with:
json
{"violations":[{"field":"steps","message":"step longer than 64 chars"},
{"field":"steps","message":"duplicate step: df -hT / /home; ..."}]}
It names the offending step for duplicates but for length it does not say which one. I binary-searched the lengths with a shell loop on adam-master to find it. It also did not flag the shell-syntax problems, the locale-dependent df parsing, or that --state is long-form-only against a 64-char budget.
Fix: propose steps: [{id, run, allow_failure?, timeout_seconds?, description?}]. If the flat string[] must stay for compatibility, add a server-side "looks like a command" check and a lint that echoes offending step index and length.
Acceptance criteria
Issue #89 — Typed steps carrying id / allow_failure / timeout_seconds / description
Branch:
issue/89-typed-steps(fromorigin/agent-develop@d6bb5c3).Worktree:
/home/eduardez/workspace/gotoi-wt/issue-89.What is actually wrong (verified on the base)
Plan.steps: string[](middleware/src/types.ts:10) pipes each entry tosh -c. The onlyvalidators are
validatePlanDraft(middleware/src/plans.ts:98-159): empty,>64chars(
STEP_MAX, L11), duplicate, forbidden token. Three concrete gaps:step longer than 64 chars— it names neither the offending index nor the actual length.Duplicates (L120) embed the text but still no index.
UC-MW-32/UC-MW-38accept this today.POST /plans {steps:['Clean the disk now']}stores the plan (201). The prose only failsat run time inside
sh -c, reported as an opaquecommand not foundstep result.command not foundappears nowhere inmiddleware/srcormiddleware/tests— there is nocreate-time check at all.
id, noallow_failure, notimeout_seconds. Realrepo plans hand-write ids in the generated
gotoi.yaml(stepsToWorkflowYaml,middleware/src/workflow.ts:346-352, already emitsid: step-${i+1}), but the invitation(
POST /plans,PATCH /plans/:id, thecreate_plan/plan_updatecontrol tools) can onlysend bare
string[], so an id can never be chosen andallow_failure/timeout_secondscannot be expressed at all.
Hard constraint that shapes the fix:
Plan.stepsisstring[]on the wire, is read by the Goagent as
JobResp.Steps []string(agent/main.go:588-634), is mirrored bydashboard/src/lib/types.ts:56, and is pinned by tests (uc-mw-cluster6-remaining.test.ts:178,uc-mw-136-ai-read-table.test.ts:229,uc-mw-autonomy-loop.test.ts:286). Changing its valueshape breaks all of that at once.
The one behaviour change
Keep
