Summary

  • Adds an OpenSpec change proposal (no implementation) for an optional depends_on: string[] field on change metadata (.openspec.yaml), naming other active changes this one builds on.
  • openspec new change would accept an optional --depends-on <name>[,<name>...] flag, validated against currently active changes at creation time.
  • openspec validate would gain always-on cross-change checks (unresolved/self-referential depends_on, dependency cycles), plus an opt-in --check-dependencies flag that reports informational (non-blocking) findings when two active changes share a capability path with no depends_on declared between them.
  • openspec list would surface the relationship: a "Blocked by" column (table) and the raw depends_on array (--json), only when a change sets it.
  • design.md covers how /opsx:explore would use --check-dependencies: it asks the user once, up front, whether to check for dependencies during the session, rather than deciding on its own — the check itself is deterministic (capability-path overlap), while judging whether a finding is a real dependency stays an agent/user call, confirmed before anything is written.
  • Modified capabilities: change-creation, cli-list, cli-validate.

Closes #1915

Why

Nothing records that one in-flight change only makes sense once another lands — today the only way to discover that add-oauth-scopes needs add-oauth-provider first is to read both proposals by hand, and openspec list treats every change as independent. This is the ordering counterpart to the priority/author triage metadata in #1899 (see #1922): that surfaces what matters, this surfaces what order.

Scope

Per CONTRIBUTING.md, this PR contains only openspec/changes/add-depends-on-metadata/ (proposal + design + spec deltas) — no implementation code.

Testing

  • openspec validate add-depends-on-metadata --strict passes.

AI disclosure

This proposal was drafted with Claude (Claude Sonnet 5, via Claude Code) based on my requirements and back-and-forth review, including a design revision after I asked for the dependency-detection behavior to be an explicit opt-in (a --check-dependencies flag) rather than an implicit agent judgment call; I've read and confirmed it reflects what I want built.

📝 Walkthrough

Walkthrough

The pull request adds OpenSpec metadata and design specifications for optional depends_on relationships, creation and validation rules, dependency-aware listing, capability-overlap checks, and interactive dependency confirmation in /opsx:explore.

Dependency metadata and CLI requirements

Dependency metadata and CLI requirements
openspec/changes/add-depends-on-metadata/.openspec.yaml, openspec/changes/add-depends-on-metadata/proposal.md, openspec/changes/add-depends-on-metadata/specs/*
The proposal defines optional depends_on metadata, --depends-on creation input, dependency validation, cycle errors, dependency-aware list output, JSON preservation, and the opt-in --check-dependencies validation flag.

Dependency detection and explore workflow

Layer / File(s) Summary
Dependency detection and explore workflow

The design specifies capability-path comparison, informational findings, interactive /opsx:explore checks, user-confirmed metadata writes, staged delivery, risks, and open questions.

Merge Risk: 🟡 Moderate · up to 57095

The proposed Explore flow can persist an invalid dependency cycle if validation or rollback is interrupted, so the pre-write graph check should be resolved before merge.

Full details: Linked Issues check

Explanation

The proposal covers the depends_on field, explicit --depends-on creation, list and JSON output, unresolved/self/cycle validation, opt-in capability-overlap findings, and user-confirmed suggestions in /opsx:explore for #1915. It does not require openspec new change to inspect the new change's scope against active changes and propose dependencies. The design explicitly limits openspec new change to the explicit flag, and change-creation/spec.md has no detection or suggestion scenario.

Resolution

Add proposal, design, and change-creation specification requirements for automatic dependency candidate detection during openspec new change, including user confirmation before metadata is written and automated scenarios. If this behavior is not intended, resolve the scope with #1915 before merge.

Explanation

Docstring coverage is 75.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 4 functions across 11 files. (1 skipped: 1 unsupported.)

Inline comments:
In `@openspec/changes/add-depends-on-metadata/design.md`:
- Around line 88-90: Update the Explore flow that writes depends_on metadata in
.openspec.yaml to validate the proposed dependency graph before persisting the
edge. Reuse the existing change-existence and self-reference checks, and add
transitive cycle detection so edges such as C → A are rejected when A → B → C
already exists; only write the metadata after all checks pass.

In `@src/core/change-metadata/schema.ts`:
- Line 35: Update the author field validation in the change-metadata schema to
reject C0 control characters and DEL, preventing terminal control sequences from
reaching ListCommand output; preserve the existing optional and non-empty
validation for valid author values.

In `@src/utils/change-utils.ts`:
- Line 218: Use presence checks for explicit author values: in
src/utils/change-utils.ts lines 218-218, update the author resolution and
payload construction around authorOverride so only undefined triggers Git
configuration fallback and explicit values, including empty strings, are
preserved for schema validation; in src/commands/workflow/new-change.ts lines
158-158, forward options.author whenever it is defined, including an empty
value.

Adds an OpenSpec change proposal (no implementation) for an optional
depends_on field on change metadata, surfaced in `openspec list` and
checked by `openspec validate` (existence/self-reference/cycle
detection, plus an opt-in --check-dependencies capability-overlap
suggestion). Includes a design.md covering the detection mechanism and
how /opsx:explore hooks into it with an explicit user opt-in.

Closes Fission-AI#1915
