ACP Registry OpenCode V2 2.1.4 advertises commands without $-prefixed skills. With installed user or project skills, its $ picker is empty even though the native OpenCode provider using the same binary lists them.
Discover installed filesystem skills for the selected workspace when the registry agent is opencode-v2. Follow OpenCode 2.1 root ordering, environment flags and duplicate precedence, preserve skills advertised by ACP, and bound filesystem reads and metadata parsing. Other ACP agents keep their existing discovery behavior.

Exported desktop frames are 1280×800; narrow frames are 780×1800. Fonts settled, motion/caret disabled; paired stable frames 500ms apart were identical.

Captures precede the parser-only follow-up 44e0c9a846; both final reviewers confirmed that its EOF/bare-opener cases leave the captured valid fixtures unchanged.

V2 details are after-only: the empty baseline inventory cannot reach a selected skill through the real picker.

Recordings (written step/timestamp narration in the index):
Public reproduction trace: seed-fixture.sh, capture-driver.js, compare.py, runtime-transcript.md.
Visible changes: the empty $ and slash results become skill rows with descriptions and source badges; selected skills expose the existing details/instructions UI; literal references become context chips, changing their padding and line wrapping. No other visible change appears outside the compared skill regions.
Unverified: native mobile device access is disabled in this environment; Electron shell smoke was not run. V2 has no reachable baseline equivalent. Supplemental long/global/instruction stills do not have the full stable-frame matrix. The index lists remaining fixture gaps; responsive web is not claimed as native verification.
Discovery is scoped to installed filesystem roots. Config-declared, URL, plugin and builtin skill sources are omitted. Frontmatter parsing has bounded fallback behavior, and differs from OpenCode's parser for some date inputs. Project-specific ACP command probing is unchanged.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This fix adds substantial automatic filesystem scanning, precedence handling, and frontmatter parsing to expose OpenCode V2 skills on an existing ACP path. It changes the runtime skill inventory for configured instances, so the scope and behavior warrant human review.

Adds filesystem-based skill discovery for OpenCode ACP across user, project, and system roots. Registry-backed OpenCode v2 provider snapshots can include discovered skills for a selected working directory. Tests cover root precedence, filtering, frontmatter handling, and workspace-specific integration.
Changes: OpenCode ACP skills
| Layer / File(s) | Summary |
|---|---|
Discovery inputs and root selection packages/provider-acp-registry/src/server/opencodeAcp.ts, packages/provider-acp-registry/package.json | Adds YAML frontmatter parsing, discovery limits, platform-specific config paths, environment-based root selection, and the yaml dependency. |
Scan roots and resolve skills packages/provider-acp-registry/src/server/opencodeAcp.ts, packages/provider-acp-registry/src/server/opencodeAcp.test.ts | Scans selected roots, loads and deduplicates skills, and sorts results. Tests cover root precedence, ignored directories, disable flags, and frontmatter cases. |
Add skills to workspace snapshots packages/provider-acp-registry/src/server/driver.ts, packages/provider-acp-registry/src/server/driver.test.ts | Registry-backed OpenCode v2 instances receive a snapshotForCwd callback. It adds discovered skills whose names are absent from the current snapshot. Tests verify workspace-specific discovery and the absence of this callback for other agents. |

Explanation
The description includes all required sections. It explains the problem, implementation, scope and issue reference, focused verification results, UI evidence, limitations, and the models and harnesses used.
Explanation
The filesystem skill discovery, workspace snapshot enrichment, precedence handling, bounded scanning, parser tests, and dependency update support the installed-skill objective for issue #24375. The summary states that other ACP agents retain their existing behavior. No unrelated product change is demonstrated.
Explanation
Issue #24375 requires project-scoped ACP commands to appear for the selected workspace. This includes / commands and $-prefixed command-derived skills. The PR adds snapshotForCwd filesystem skill discovery for opencode-v2, but the supplied summary states that project-specific ACP command probing is unchanged. The new tests cover filesystem skill discovery and do not establish workspace-scoped ACP command probing. The incremental repository diff was unavailable, so this conclusion uses the supplied whole-PR summary and issue requirements.
Resolution
Probe ACP Registry providers with the selected workspace cwd and refresh the probe per workspace. Add automated coverage for project / commands and $-prefixed command-derived skills. Preserve the new filesystem skill discovery behavior.

Fixed the EOF-frontmatter finding in 44e0c9a846. The updated cases fail before the fix and pass afterward; 59/59 package server tests, typecheck, lint and format pass. Both final isolated reviewers approved. The existing runtime captures use valid closed frontmatter and remain applicable. The linked-issue warning concerns project-specific ACP command probing, which is outside this installed-skill discovery change and is explicitly disclosed in the PR scope.
