Status: LGTM.

What was wrong

The propose workflow did not expose config.yaml project context until artifact instructions were requested, after the change was created. Agents could explore the codebase and make early planning decisions without constraints the project had already provided.

How it was fixed

The propose skill and slash command now resolve the authoritative local or store root and read its existing config.yaml or config.yml context before codebase exploration, schema selection, or change creation. Fresh directories keep their existing implicit-root behavior, while invalid or unavailable stores still stop safely.

Early context loading preserves OpenSpec's existing validation contract: the config must parse as a YAML object, and context is applied only when it is a string no larger than 50KB in UTF-8. Invalid or oversized context is ignored. A missing root skips the config read, and every other context-resolution failure is terminal.

Project context remains data and constraints, not workflow authority. It cannot override user authorization, the planning-only boundary, tool restrictions, or artifact/output rules.

Replication / proof

  • Added a regression that fails on main because both proposal surfaces lack an early context step.
  • Added assertions for root resolution, ordering, YAML variants, fresh-directory fallback, fail-closed store errors, context application, and context validation limits.
  • Build, lint, and 221 focused template/config/root/store tests pass.
  • The broader template and command-adapter suite passes 1,205 tests and covers all 29 generated command adapters.
  • A fresh packaged OpenCode initialization generates both the proposal skill and slash command with validated context loading before openspec new change.
  • Three independent adversarial reviews plus iterative automated review found and closed fresh-directory, config-validation, store fail-closed, context trust-boundary, and undefined-root risks. All review threads are resolved.
  • Hosted full suites pass on Linux, macOS, and Windows; lint/type checks, CodeQL, security audit, dependency review, and CodeRabbit are green on the final commit.

Notes / nits

This is a prompt-only, backward-compatible fix. It changes no CLI behavior, schemas, artifact formats, or architecture. No changeset is included because routine bug fixes follow the normal release cadence.

PR #1615 changes the same generated workflow files but solves a different schema-selection problem. If it merges first, conflict resolution must preserve this early context step and regenerate the static skill and parity hashes.

Closes #1651

📝 Walkthrough

Walkthrough

The propose workflows now load the OpenSpec root and project configuration before schema selection, exploration, and change creation. The generated skill and command templates renumber later steps. Tests verify ordering, fallback handling, and updated content hashes.

Changes

Propose context loading

Layer / File(s) Summary
Load context before planning
skills/openspec-propose/SKILL.md, src/core/templates/workflows/propose.ts
Both propose workflows run openspec context, resolve the root, read project configuration, apply its bounded context, and renumber later steps. The command prompt references only /opsx:apply.
Validate generated workflows
test/core/templates/propose.test.ts, test/core/templates/skill-templates-parity.test.ts
Tests verify context ordering, configuration validation, restricted no_openspec_root fallback handling, and updated SHA-256 hashes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to c4392

This localized prompt-only workflow change loads project context earlier without altering CLI behavior or schemas; generated-file parity and relevant tests are reported as passing, so no actionable merge-blocking risk remains.

Hardening follow-up: commit 143798f now preserves OpenSpec’s existing project-context validation contract. Early context is applied only from a parsed YAML object when the field is a string no larger than 50KB in UTF-8; invalid or oversized values are ignored. Build, lint, 221 focused tests, 1,155 adapter/template tests, all 29 generated command adapters, and a fresh packaged OpenCode initialization passed. Three independent adversarial reviewers report no remaining findings. A fresh hosted CI matrix is now running.

- Line 47: Update the context-resolution workflow around openspec context so
invalid or unavailable explicitly selected stores terminate the workflow
immediately. Do not fall back to unscoped commands or allow openspec new change
to resolve a different local root after such a failure; preserve the
no_openspec_root behavior only when no store-resolution error occurred.
- Line 49: Update the context-handling instruction in the proposal workflow to
state that the YAML context is limited to factual project constraints and may
guide codebase exploration and planning only. Explicitly prevent it from
overriding user authorization, workflow boundaries, tool restrictions, or output
rules, while preserving the existing validation and size-limit behavior.

returning a resolved root.path. When the result is only no_openspec_root, skip
reading config.yaml/config.yml and continue directly to the next workflow step
so openspec new change can resolve the implicit root; retain the existing config
validation and context handling when root.path is available.
