makeClaudeUserMessage (ClaudeAdapterV2.ts) used planClaudeSkillDispatch to split any prompt mentioning a known skill into a leading text block plus a trailing /skill block. Claude only runs /goal when it opens the prompt, so /goal ... $skill ran the skill and never set a goal, while the server's parseGoalCommand still classified the message as a goal command. Fix: when parseGoalCommand recognises the text as a goal command, the message content is one string, the dispatch's leadingText (the whole prompt with skill mentions rewritten inline as /name), falling back to the raw text. The issue's CLI experiment showed that payload sets the goal and still invokes the skill. Messages with attachments are never goal commands (parseGoalCommand returns null), so the attachment path is unchanged. No new regex or parser: the change reuses the existing parseGoalCommand. The repro test from factory/repro-29750 is kept and now passes; before the fix it failed with 'expected [...] to be a string'.

Fixes #29750

Reproduction on main

Commit 62dc589 (origin/main). Started T3CODE_DEV_SEED=0 vp run dev in a fresh worktree, paired the web client, added a local-folder project containing one project skill probe-skill (reply PROBED), picked Claude Haiku 5.5, and sent one message: /goal Reply DONE. / say hi / the probe-skill chip from the $ menu (sent text /goal Reply DONE.\nsay hi\n$probe-skill). Result: the turn finished with the reply PROBED, no goal banner or Goal set message appeared, and in the worktree's statev2.sqlite the goal is null on both orchestration_v2_projection_threads and orchestration_v2_projection_provider_threads for that thread. Separately, the installed Claude CLI (stream-json, haiku) given the payload main builds (two text blocks: the whole prompt, then /probe-skill) emitted no Goal set and just ran the skill. Given the same prompt as one string it replied Goal set: Reply DONE.\nsay hi\n/probe-skill, then invoked the skill and ran the goal's stop hook. The unit test on the repro branch fails on main with expected [ { type: 'text', …(1) }, …(1) ] to be a string.

Evidence

Send /goal Reply DONE.\nsay hi\n$probe-skill, selecting the project skill from the $ menu, then wait for completion. Both sides use the real web app, fresh synthetic databases, the same Claude configuration, a 1280×800 viewport, and light theme. Private model identifiers are hidden.

Tests

vp test run src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts src/provider/Drivers/ClaudeSkillDispatch.test.ts src/provider/Drivers/ClaudeSkills.test.ts (apps/server): 3 files, 428 tests passed. Without the fix (git stash), the repro test fails with 'expected [ { type: 'text', …(1) }, …(1) ] to be a string'. vp run check:changed: the first run failed only on format; after vp fmt, format, lint, knip 1/2 and 2/2, graphql, typecheck (3 packages) and tests (2 files, 399 tests) all pass.

Not in this change

• When the last skill mentioned in a /goal message is userInvocationOnly, it is sent inline as /name without the 'Follow the instructions at ' fallback that planClaudeSkillDispatch adds to earlier user-only mentions, because the planner reserves the last mention for native expansion.
• The server records the goal objective from the raw text ($skill) while Claude's objective shows /skill; the wording differs but both name the same skill.

Approvability

Verdict: Approved at b521e8c

Macroscope's review found this PR approvable — Claude /goal requests mentioning skills now remain a single prompt so Claude can recognize the goal command. The change is limited to explicit goal requests; ordinary prompts and attachment handling remain unchanged.

Walkthrough

The Claude adapter now sends goal commands as a single content value instead of splitting them through skill dispatch. A regression test covers a goal prompt that later mentions $review. Non-goal prompts retain the existing skill-dispatch behavior.

Changes: Claude goal prompt dispatch

Layer / File(s)	Summary
Goal prompt handling and regression coverage apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	makeClaudeUserMessage detects goal commands and uses the dispatch leading text, or the original prompt when there is no leading text, as one content value. Other prompts retain the existing split skill-dispatch behavior. The regression test checks that a /goal prompt with a later $review mention remains a single string.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: t3dotgg, maria-rcks, yash-singh1

Merge Risk: Low · up to b521e

Goal messages that end with a user-invocation-only skill now set the goal, but that final skill may not run. Other skills and ordinary messages are unaffected. This is a bounded gap that can be fixed here or tracked as a follow-up.

Full details: Title check

Explanation

The title "fix(server): Claude sets a /goal that also mentions a skill" names the main change. The PR makes Claude goal commands that mention a skill send as one string, so the goal is set and the skill still runs. The title follows the conventional commit format in the repository template and is specific enough for a reader scanning history.

Full details: Linked Issues check

Explanation

Issue #29750 requires a Claude /goal message that also invokes a skill on a later line to set the goal. The diagnosis says the CLI reads /goal as a native command only when it opens the prompt, and the split into two text blocks breaks that. In makeClaudeUserMessage (ClaudeAdapterV2.ts), the diff adds isGoalCommand = parseGoalCommand({ text: input.text }) !== null. For goal commands, content becomes one string: dispatch?.leadingText ?? input.text. This removes the split for goal messages, which addresses the diagnosed cause. The added regression test in ClaudeAdapterV2.test.ts asserts that the content is a string that starts with the full /goal text and its following lines. The goal-setting and skill-invocation behavior after the fix comes from the PR author's CLI experiment, not from an app run at the reviewed head. The PR's Evidence section is still marked as being captured. I did not verify that behavior independently. Non-goal messages and messages with attachments keep the existing path.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base touches two files. ClaudeAdapterV2.ts adds the parseGoalCommand import and the goal branch in makeClaudeUserMessage. ClaudeAdapterV2.test.ts adds one regression test. Both changes serve issue #29750. The non-goal branch, the skill-dispatch planner, and attachment handling are unchanged in the diff. The PR notes two known limitations: the final userInvocationOnly mention is sent inline without the fallback instruction, and the goal objective uses $skill while Claude shows /skill. These limitations relate to the same goal path. They do not show unrelated changes.

Full details: Description check

Explanation

The description follows the repository template closely. It has a clear Problem (a /goal prompt with a later skill mention runs the skill and never sets a goal), a Change section that explains the reuse of parseGoalCommand and the leadingText payload, a Scope section that links issue #29750 and explains the bug fix, and a Verification section with a reproduction on main, before/after evidence, focused test commands with results, and a note that the failing test was observed without the fix. It also names the AI assistance. The Verification section and the Limitations section are detailed. The template's title guidance is not applicable here because the title is not in the description. Minor gap: the template asks for the model and harness used by the agent, and the author only writes 'AI-assisted' without naming the model and harness. That is non-critical, so the check passes.

Add the fallback for a final user-invocation-only skill on the goal path.

On the goal path, a final userInvocationOnly skill mention is sent inline at ClaudeAdapterV2.ts:2562. Claude Code expands a slash command only at the start of a message, and the planner never annotates the final skill. The selected skill's instructions are therefore not supplied, and Claude cannot invoke the skill through the Skill tool. The skill silently does not run, although the goal is set.

Keep the non-goal path unchanged: its final skill stays native. Add the same fallback annotation that earlier user-only mentions receive, but only for the goal branch. ClaudeSkillDispatch.ts:40 seeds annotated with the final skill for every path, so the goal branch needs its own annotation. The PR description records this as a known limitation. Decide whether to fix it in this change or track it separately.
