Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
Adds a workflow “dry-run” mode to preview rendered inputs and skip AI/interactive execution, and exposes it via CLI entrypoints.
Changes:
- Introduces
dry_runonWorkflowEngine.execute()and propagates it throughStepContext. - Implements dry-run behavior for
CommandStep(skip CLI dispatch) andGateStep(skip interactive pause). - Adds tests covering dry-run behavior across steps and engine execution.

Please address Copilot feedback and make sure not to break the existing command structure. The "--dry-run" should not introduce new commands. Note that the specify CLI is NOT the command executor. Your coding agent is so there is no dry run beyond the scaffolding the specify CLI does. Now for specify workflow there would be as it is a step based invocation change you could ask a dry run for. Please readjust this according to this design. Thanks!

- Add start_at/stop_after params to WorkflowEngine.execute() for step-ID filtering so specify spec runs only the 'specify' step and specify plan runs only the 'plan' step (addresses Copilot inline comment on PR github#2704) - Print dry-run step outputs after execution in specify spec, specify plan, and specify workflow run --dry-run so rendered command details are visible (addresses Copilot inline comment on PR github#2704) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Copilot's findings
Comments suppressed due to low confidence (1)
src/specify_cli/workflows/steps/command/init.py:129
- When a command dispatch occurs,
output['executed']should be set toTrueso downstream expressions can distinguish a real invocation from a dry-run preview (whereexecutedis forced toFalse).
if dispatch_result is not None:
output["exit_code"] = dispatch_result["exit_code"]
output["stdout"] = dispatch_result["stdout"]
output["stderr"] = dispatch_result["stderr"]
output["dispatched"] = True
- Files reviewed: 6/6 changed files
- Comments generated: 3
- PromptStep now honors context.dry_run: renders a preview with
executed=False, dispatched=False, exit_code=0, dry_run=True,
and a DRY RUN message. Without this, a workflow with
type: prompt would still spawn the integration CLI even in
dry-run mode, contradicting the docstring claim that dry_run
skips AI invocation across the board.
- workflow_run's dry-run preview loop is no longer gated on
state.status == 'completed'. Dry-run previews print regardless
of the run's final status (completed / failed / paused), so a
dry-run that fails mid-run still surfaces the prompts / command
invocations that would have been resolved up to the point of
failure. The --json branch is still suppressed (the early
return for json_output returns before the loop).
- CommandStep real-run path now sets output['executed'] = True,
and the no-dispatch (CLI-not-found) branch sets it False. The
dry-run branch already sets it False. Downstream
{{ steps.<id>.output.executed }} expressions can now reliably
key on the field regardless of which branch executed.
- New test test_dry_run_prompt_short_circuits covers PromptStep
dry-run. Existing test_dispatch_with_mock_cli now also asserts
executed is True on the real-run success path.

Re: review #4382194003 (CHANGES_REQUESTED) — design re-scopedThanks for the design guidance. The PR has been reworked to match —
Tests: I've already used my remaining reviewer-request slot trying to re-request review (API returns 404 from my fork-side, presumably a permissions boundary on the upstream repo). If you have a moment, could you re-review when convenient? Happy to address anything else you spot. |

1. command/__init__.py: Fix syntax error - else: block body was at 0 indentation instead of 24 spaces (inside the 'if impl is None' else branch). Also try/except structure was broken with except at same level as try but body leaking outside. 2. __init__.py: Guard the dry-run preview loop with 'and not json_output' so that --json mode emits only a single well-formed JSON object without per-step dry-run text polluting stdout. Fixes Copilot comments: - 3383108299 (SyntaxError from mis-indented invoke_str) - 3379546978 (mis-indentation issue) - 3379547033 (dry-run loop running with --json enabled)

Hi @mnriem — all Copilot feedback from the June9 cycle has been addressed in the latest commit (b82db41). Summary of fixes:\n\n1. command/init.py: Fixed syntax error — the else: block body was at0 indentation instead of inside the 'if impl is None' else branch. Also fixed the try/except structure.\n\n2. init.py: Guarded the dry-run preview loop with 'and not json_output' so --json mode emits only a single well-formed JSON object.\n\nThe PR head is b82db41. Ready for your re-review when you have a moment.

Summary
Implements issue #2661 — add a
--dry-runflag tospecify workflow runthat previews each step's resolved inputs, prompt, and command invocation without spawning the underlying coding-agent CLI or making any AI calls. Use it to verify what a workflow would dispatch before running for real.What ships

specify workflow run --dry-run(in-module, in__init__.py) — the only place the flag is exposed. After the run, the CLI prints anyoutput['dry_run']messages so the rendered previews surface in the terminal.What does not ship (intentional)
Per design review, the
specifyCLI is scaffolding + workflow orchestration only. The per-stage surface (/speckit.specify,/speckit.plan, ...) belongs to the agent, not the CLI. A previous draft of this PR addedspecify spec/specify planpreview commands; those have been removed along with the supportingstart_at/stop_afterstep filtering in the engine. Issue #2661's wording has been re-scoped to--dry-runonspecify workflow run.Tests
