Distillation

Date: September 10, 2026

• 🔴 (12:52) The final complete exact-tree suite passed under Vitest: 453/453 test files, 9,502 tests passed, and 16 tests skipped.
• 🟡 (12:52) Assistant planned to freeze the corrected patch in a commit, obtain an independent correctness review against the immutable base/head, and only then publish it.
• 🔴 (12:52) Work status: completed “Add fail-first regressions and fix the three correctness findings” and “Regenerate artifacts and run focused plus full validation”; in progress “Inspect final patch and freeze corrected revision in a commit”; pending “Obtain an independent correctness review of the immutable corrected head,” “Push the reviewed head to PR #1558,” “Update PR metadata and resolve bot review threads,” and “Monitor exact-head CI, merge PR #1558, and verify merged state.”
• 🔴 (12:52) Git branch was fix/agent-conversation-reference-root-cause; its tracked remote origin/pr-1558 was marked [gone].
• 🔴 (12:52) The uncommitted patch modified 9 files with 191 insertions and 44 deletions: packages/cli/script/generate-command-docs.ts, packages/cli/src/commands/agent-conversation/view.ts, packages/cli/src/lib/command.ts, packages/cli/src/lib/introspect.ts, packages/cli/test/lib/help-positional.test.ts, packages/cli/test/lib/introspect.property.test.ts, packages/cli/test/lib/introspect.test.ts, packages/cli/test/lib/scanner-flags.integration.test.ts, and packages/cli/test/script/generate-skill-markdown.test.ts.
• 🔴 (12:53) In packages/cli/script/generate-command-docs.ts, formatPositionalsTable() now constructs positional syntax as <${p.placeholder}${p.variadic ? "..." : ""}> and encloses that value in brackets only when p.optional is true. This distinguishes required variadic syntax such as <args...> from optional fixed syntax such as [<arg>].
• 🔴 (12:53) In packages/cli/src/commands/agent-conversation/view.ts, the target positional was marked optional: true, and func() changed from target: string to target?: string.
• 🔴 (12:53) In packages/cli/src/commands/agent-conversation/view.ts, omitted and blank conversation targets now have separate behavior: target === undefined throws new ContextError("Conversation ID", USAGE_HINT, []), while !target.trim() throws validationError("Conversation ID cannot be empty.", [USAGE_HINT], "conversation-id").
• 🔴 (12:53) In packages/cli/src/lib/command.ts, attachDocumentationMetadata() now types command metadata with formatUsageLine: (args: { readonly prefix: readonly string[] }) => string; when a primary custom usage exists, it stores the normalized string in metadata.__primaryUsage and overrides metadata.formatUsageLine to return [...prefix, input].join(" ").
• 🔴 (12:53) In packages/cli/src/lib/introspect.ts, PositionalInfo gained variadic: boolean; placeholder is explicitly documented as excluding angle brackets and variadic ellipses, brief may be an empty string, and optional describes whether a fixed tuple parameter may be omitted.
• 🔴 (12:53) In extractPositionals() in packages/cli/src/lib/introspect.ts, fixed tuple positionals now set variadic: false, retain optional: p.optional ?? false, and use p.placeholder ?? \arg${i}``.
• 🔴 (12:53) In extractPositionals() in packages/cli/src/lib/introspect.ts, array parameters no longer append ... to placeholder; they now return placeholder: params.parameter.placeholder ?? "args", optional: false, and variadic: true.
• 🟡 (12:53) Assistant assessed that the production diff was narrow and matched the three correctness findings, and identified the integration-test harness changes as the next review target because they accounted for most changed lines and needed verification that they did not weaken existing parser assertions.
