How it fires
How this agent gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

YOUR TASK
Extract structured requirements from the interview conversation and format them for Seed YAML generation.
When a deterministic Requirement Promotion Policy is supplied, it is authoritative: only candidates listed as promoted may become hard requirements or acceptance criteria. Reference-derived and model-inferred omitted candidates remain hypotheses. Never turn a product reference, glossary explanation, visual taste signal, or model guess into an acceptance criterion without explicit user confirmation in the promoted set.
READING THE TRANSCRIPT
Answers carry a provenance marker naming where they came from. `[from-user]` (or no marker) is a decision the user made. `[from-code]`, `[from-repo]`, and `[from-research]` are facts the user adopted from somewhere else — the state of an existing system, or something looked up — and a fact is not a decision. Only a decision can become a requirement.
Where an adopted fact would otherwise appear, you will see instead:
A: [observation withheld — an adopted fact, not a decision. It informed the questions that follow.]
That is deliberate, not a truncation or an error. Do not ask for the content, do not guess at it, and do not treat the note itself as a requirement. The requirement the user drew from that fact is in their own answer, in their own words — extract that.
Questions are shown in full, including any that restate an adopted fact. A question exists to make the answer that follows interpretable; it is not itself a decision, and nothing in a question line becomes a requirement on its own.
COMPONENTS TO EXTRACT
1. GOAL
A clear, specific statement of the primary objective. Example: "Build a CLI task management tool in Python"
2. CONSTRAINTS
Hard limitations or requirements that must be satisfied. Format: single-line JSON array of strings. Values may contain any characters, including literal `|` pipes; never use a bare pipe as the list separator. Example: ["Python >= 3.12", "No external database", "Must work offline"]
3. ACCEPTANCE_CRITERIA
Specific, measurable criteria for success. Format: exactly one non-empty, single-line JSON array. Every object contains exactly `description`, `verify`, `artifacts`, and `expect`. `artifacts` is a JSON array of paths or the string `NONE`; the other contract fields are strings. Example: `[{"description":"Tasks can be created","verify":"python -m pytest tests/test_tasks.py -q","artifacts":"NONE","expect":"NONE"}]` Multi-artifact example: `[{"description":"Build outputs exist","verify":"NONE","artifacts":["dist/app","docs/User Guide.md"],"expect":"NONE"}]`
`verify` / `verify_command` semantics:
- Use exactly one single-line shell command.
- NEVER use heredoc or multiline shell syntax such as `<<`, `<<'PY'`, `cat <<EOF`, line-continuation scripts, or an unterminated command block. The AC contract format is one line, so multiline command bodies will be lost.
- For Python snippets, use `python -c "..."` / `python3 -c "..."`; for longer checks, require a pytest-discoverable test artifact and use `python -m pytest -q`.
`artifacts` / `expected_artifacts` semantics:
- Every entry is an exact portable file or directory path relative to the run workspace. The runner resolves each entry literally and requires it to exist.
- Encode multiple entries as one JSON array, for example
`"artifacts":["dist/app","docs/User Guide.md"]`.
- Do not put commas or backslashes inside artifact paths.
- NEVER use a descriptive label such as `schema v2 outputs` or `user approval record` as an artifact path.
- Prefix a top-level file or directory containing spaces with `./`, for example `./Build Outputs`; nested paths such as `docs/User Guide.md` are already explicit.
- If no exact path is known, write `artifacts: NONE` and provide a concrete `verify` command instead.
- File or directory existence can be a complete contract. For a stateful artifact that can still be pending or blocked, also provide a `verify` command that checks its semantic state.
`expect` / `output_assertion` semantics:
- Use `expect` ONLY for a literal string present verbatim in the verify command's combined stdout and stderr, such as `OK` or `5 passed`.
- NEVER use a condition, status, or exit-code description such as `exit code 0`, `exit 0`, `returns 0`, `success`, `no errors`, `passed`, or `passes`.
- If the command has no distinctive output literal to assert, write `expect: NONE`. Exit-code 0 is already verified separately by the runner.
**Granularity contract (read carefully):**
An acceptance criterion names a **state of the finished work** that a user can see is true. An implementation step names a **means of reaching that state**. These are different categories, and only the first belongs here — deciding means is the execution engine's work at runtime, and it decides them better with the outcome in hand than with your guess at the path.
So the question to ask of every criterion is what kind of thing it is. Read it beside its siblings: if it stands on its own as something a user would value, it is an outcome. If it is intelligible only as a move toward a sibling, it is that sibling's means wearing an outcome's clothes, and it belongs merged into the outcome it serves. Leaving a means in the criteria list is a defect equal in severity to a missing requirement — it commits the seed to a path before anyone has verified the path is the right one.
How many criteria a goal has is a property of that goal, discovered by making this judgment.
4. ONTOLOGY
The data structure/domain model for this work:
- **ONTOLOGY_NAME**: A name for the domain model
- **ONTOLOGY_DESCRIPTION**: What the ontology represents
- **ONTOLOGY_FIELDS**: Key fields as a single-line JSON array of objects with "name", "type" (string, number, boolean, array, object), and "description"
