Project-local Cash CLI bootstrap

執行任何 Cash artifact command 前，MUST 先從目前目錄解析並驗證 Git root，再使用該 root 下的 absolute launcher；不得依賴 PATH 或外部 runtime：

cash_root="$(git rev-parse --show-toplevel)" || exit 1
cash_cli="$cash_root/.cash-skills/bin/cash"
test -x "$cash_cli" || exit 1

同一段 workflow 後續每個 artifact command MUST 使用 "$cash_cli"。

Update an existing Cash change — from a plan file or conversation context.

This tool resolves plan file references as ordinary paths relative to the current working directory or repository root, and uses conversation context when no plan file is available.

Prerequisites: The project-local launcher initialized above is required. If root resolution, launcher validation, or a Cash command fails, report the exact error and STOP.

Input: Optionally specify a plan file path or name.

• $cash-ingest agile-discovering-rocket.md
• $cash-ingest agile-discovering-rocket
• $cash-ingest (use conversation context or auto-detect plan file)

Response language: All user-facing responses in this workflow MUST be written in Traditional Chinese unless the user explicitly requests another language. Keep shell commands, file paths, code identifiers, schema field names, and quoted source text verbatim.

Steps

1. Locate the requirement source

   a. Argument provided → treat as a plan file reference, resolve it relative to the current working directory or repository root, and append .md if needed

   • If the file exists → use it as the plan file source, proceed to Step 2
   • If the file does NOT exist → report the error and stop

   b. No argument, plan file detectable:

   • Check conversation context for a plan file path (plan mode system messages include paths like <name>.md); resolve it relative to the current working directory or repository root
   • If found and the file exists → use the AskUserQuestion tool to ask:
     • Option 1: Use the plan file
     • Option 2: Use conversation context
   • If the user picks plan file → proceed to Step 2
   • If the user picks conversation context → skip Step 2, go to Step 3

   c. No argument, no plan file detectable:

   • Check the current working directory and repository root for recent plan files
   • If recent files exist → list 5 most recent with the AskUserQuestion tool, include "Use conversation context" as an additional option
   • If the user picks a file → proceed to Step 2
   • If the user picks conversation context → skip Step 2, go to Step 3

   d. Conversation context fallback (no plan files found at all):

   • Use conversation context to update artifacts
   • If conversation context is insufficient, use the AskUserQuestion tool to get more details
   • Warn: "No plan file found. Using conversation context."

2. Parse the plan structure (skip if using conversation context)

   Claude Code plan files typically contain:

   • Title (# ...) — the high-level goal
   • Context section — background, motivation, current state
   • Stages/Steps — numbered implementation stages with goals and file lists
   • Files involved — list of files to modify/create
   • Verification section — how to test the changes

   Extract:

   • plan_title: from the H1 heading
   • plan_context: from the Context section
   • plan_stages: each numbered stage with its goal and file list
   • plan_files: all file paths mentioned
   • plan_verification: verification steps

   If the plan content is too brief to fill the required artifact sections, use the AskUserQuestion tool to get the missing details rather than inventing content.

3. Check for active changes (REQUIRED — ingest only updates existing changes)

   "$cash_cli" list --json
   

   Also check for parked changes:

   "$cash_cli" list --parked --json
   

   Parse both JSON outputs to get the full list of changes (active + parked). Parked changes should be annotated with "(parked)" in any selection list.

   • If one change exists (active or parked) → use the AskUserQuestion tool to confirm updating it
   • If multiple changes exist → use the AskUserQuestion tool to let user pick which one to update
   • If no changes at all (neither active nor parked) → tell the user: "No active change found. Use $cash-propose first to create one." and stop

4. Select the change

   After selecting the change, check if it is parked:

   "$cash_cli" list --parked --json
   

   If the selected change appears in the parked array:

   • Inform the user that this change is currently parked（暫存）
   • Use AskUserQuestion tool to ask: continue (unpark) or cancel
   • If continue: run "$cash_cli" unpark "<name>" then proceed
   • If cancel: stop the workflow

   Read existing artifacts for context before updating.

5. Update artifacts

   For each artifact, get instructions first:

   "$cash_cli" instructions <artifact-id> --change "<name>" --json
   

   Use the template from instructions as the output structure. Apply context and rules as constraints but do NOT copy them into the file.

   The instructions JSON includes locale — the language to write artifacts in. If present, you MUST write the artifact content in that language. For spec files (specs/*/*.md), the spec-file language policy takes precedence over locale: Traditional Chinese prose with English structural keywords (### Requirement:, #### Scenario:, GIVEN/WHEN/THEN/AND) and English normative verbs (SHALL / MUST and their NOT forms); every MODIFIED/REMOVED requirement title and every RENAMED FROM title MUST be copied byte-for-byte from the current master spec, because "$cash_cli" archive matches titles verbatim and fails closed with requirement_identity_mismatch when a title does not match.

   Plan-to-Artifact Mapping (when using a plan file):

   Plan Section	Artifact	How to Map
   Title	Change name	Convert to kebab-case
   Context	proposal: Why	Direct content transfer
   Stages overview	proposal: What	Summarize all stages
   Individual stages	tasks.md groups	One stage = one ## heading, sub-items = - [ ]
   File paths	proposal: Impact	Affected code list
   Verification steps	tasks.md	Final verification task group

   Context-to-Artifact Mapping (when using conversation context):

   Conversation Element	Artifact	How to Map
   Goal / requirement	proposal: Why	Extract motivation from discussion
   Discussed approach	proposal: What	Summarize agreed approach
   Mentioned files	proposal: Impact	Affected code list
   Discussion phases	tasks.md groups	One topic = one ## heading

   When updating an existing change:

   • Merge new context into existing proposal (don't replace)
   • Add new tasks from plan stages or conversation, preserve completed [x] items
   • Preserve existing [P] markers on tasks that still qualify
   • Do NOT remove existing content

   Parallel task markers ([P]): When creating or updating the tasks artifact, first read .cash.yaml. If parallel_tasks: true is set, add [P] markers to new tasks that can be executed in parallel. Format: - [ ] [P] Task description. A task qualifies for [P] if it targets different files from other pending tasks AND has no dependency on incomplete tasks in the same group. When parallel_tasks is not enabled, do NOT add [P] markers — but still preserve any existing [P] markers already in the file.

   After creating each artifact, re-check status:

   "$cash_cli" status --change "<name>" --json
   

   Continue until all applyRequires artifacts are complete. Show progress: "✓ Created "

6. Inline Self-Review (before CLI analysis)

   After updating all artifacts, scan them manually. Fix issues inline, then proceed to the CLI analyzer.

   Check 1: No Placeholders

   These patterns are artifact failures — fix each one before proceeding:

   • "TBD", "TODO", "FIXME", "implement later", "details to follow"
   • Vague instructions: "Add appropriate error handling", "Handle edge cases", "Write tests for the above"
   • Delegation by reference: "Similar to Task N" without repeating specifics
   • Steps describing WHAT without HOW: "Implement the authentication flow" (what flow? what steps?)
   • Empty template sections left unfilled
   • Weasel quantities: "some", "various", "several" when a specific number or list is needed

   Check 2: Internal Consistency

   • Does every capability in the proposal have a corresponding spec?
   • Does the design reference only capabilities from the proposal?
   • Do tasks cover all design decisions, and nothing outside proposal scope?
   • Are file paths consistent across proposal Impact, design, and tasks?
   • If a requirement changed, were its scenarios updated to match?

   Check 3: Scope Check

   • More than 15 pending tasks → consider decomposing into multiple changes
   • Any single task would take more than 1 hour → split it
   • Touches more than 3 unrelated subsystems → consider splitting

   Check 4: Ambiguity Check

   • Are success/failure conditions testable and specific?
   • Are boundary conditions defined (empty input, max limits, error cases)?
   • Could "the system" refer to multiple components? Be explicit.

   Check 5: Preservation Check (ingest-specific)

   • Are all completed tasks [x] still present and unchanged?
   • Are completed tasks still relevant to the updated scope? If new context conflicts with one, report the conflict without rewriting the completed task.
   • Were existing [P] markers preserved on tasks that still qualify?
   • Was existing content merged (not replaced)?

   Check 6: Durable Handoff Review (run BEFORE the CLI analyzer)

   The updated change has to survive being parked or handed to another agent. Reject and fix any of the following on incomplete design and task content (do not rewrite completed [x] tasks):

   • File-path-only tasks: a pending task whose entire description is "edit file X" with no behavior, contract, or verification target. File paths are locator context — the task SHALL still describe what is observably true when complete.
   • Line-number-coupled instructions: design or task content that points to "line 42" / "the function on lines 80-95" as the only way to identify the work. Source line numbers drift; name the function, command, struct, or behavior instead.
   • Vague acceptance criteria: success conditions like "works correctly", "behaves as expected", "handles edge cases" without naming the observable behavior or the verification target (test name, CLI invocation, analyzer rule, manual assertion).
   • Missing scope boundaries on non-trivial work: design lacking explicit "in scope" / "out of scope" lines for any change that touches more than one subsystem or introduces new behavior. Trivial artifact-only edits MAY skip this; runtime, build, or tooling effects MUST NOT.

   Fix every failure inline using the existing context and the new plan/conversation source before running the CLI analyzer. Update incomplete design and task content so behavior contracts, verification criteria, and scope boundaries stay current with the new context. Preserve completed tasks unchanged.

7. Analyze-Fix Loop (max 2 iterations)

   "$cash_cli" analyze <name> --json
   

   1. Filter findings to Critical and Warning only (ignore Suggestion)
   2. If no Critical/Warning findings → show "Artifacts look consistent ✓" and proceed
   3. If Critical/Warning findings exist: a. Show: "Found N issue(s), fixing... (attempt M/2)" b. Fix each finding in the affected artifact c. Re-run "$cash_cli" analyze <name> --json d. Repeat up to 2 total iterations
   4. After 2 attempts, if findings remain:
      • Show remaining findings as a summary
      • Proceed normally (do NOT block)

8. Validation

   "$cash_cli" validate "<name>"
   

   If validation fails, fix errors and re-validate.

9. Summary and next steps

   Show:

   • Source used: plan file (<path>) or conversation context
   • Change name and location
   • Artifacts created/updated
   • Validation result

   Use AskUserQuestion tool to confirm the workflow is complete. This ensures the workflow stops even when auto-accept is enabled. Provide exactly these options:

   • First option (will be auto-selected): "Done" — End the ingest workflow. Inform the user they can run $cash-apply <change-name> when ready.
   • Second option: "Apply" — Invoke $cash-apply <change-name> to start implementation.

   If AskUserQuestion tool is not available, display the summary and inform the user to run $cash-apply <change-name> when ready. Then STOP — do not continue.

   After the user responds, if they chose "Done", the workflow is OVER. If they chose "Apply", invoke $cash-apply <change-name> to begin implementation.

Guardrails

• NEVER modify the original plan file, regardless of its resolved location
• NEVER write application code — this skill only creates/updates Cash artifacts
• NEVER create new changes — ingest only updates existing changes. If no active change exists, direct user to $cash-propose
• NEVER skip the artifact workflow to write code directly
• If AskUserQuestion tool is not available, ask the same questions as plain text and wait for the user's response
