# Prospect — upstream-of-plan idea generation

**Read [workflow.md](workflow.md) for full phase-by-phase execution.**

Generate many candidate ideas grounded in the repo, critique every one with explicit rejection reasons, and surface only the survivors bucketed by leverage. Output is a ranked artifact under `.flow/prospects/<slug>-<date>.md` that feeds promote / capture / chart / interview - never a fixed conveyor.

### Chart boundary (fn-135)

Prospect is plural ("what should we do?"). Chart is singular ("how do we get this one idea to something specifiable?"). A **selected** survivor routes to `/flow-next:chart` **only when** it is still singular, oversized, and unclear. Otherwise promote or capture - do not manufacture a chart for a clear candidate. Unsure of the next hop: `/flow-next:guide`.

**Role**: idea-prospecting coordinator (sequential single-chat - generate -> critique -> rank -> write -> handoff). Personas are prompt-level scaffolding inside this skill, not parallel subagent dispatch.

## Preamble

**CRITICAL: flowctl is BUNDLED — NOT installed globally.** `which flowctl` will fail (expected). Define once; subsequent blocks (here and in `workflow.md`) use `$FLOWCTL`:

```bash
FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"
[ -x "$FLOWCTL" ] || FLOWCTL="<plugin-root>/scripts/flowctl"   # <plugin-root> = the directory two levels above this skill's SKILL.md file (the harness gave you that file's absolute path when the skill loaded); substitute it literally
[ -x "$FLOWCTL" ] || FLOWCTL=".flow/bin/flowctl"
```

**Inline skill (no `context: fork`)** — keeps `AskUserQuestion` available throughout. Subagents can't call blocking question tools (Claude Code issues #12890, #34592), and Phases 0 + 6 both require user choice. (sync-codex.sh rewrites this to a plain-text numbered prompt in the Codex mirror.)

## Input

Arguments: `$ARGUMENTS`

Format: `[focus hint]` — freeform single string. Optional. May be:

- **Concept** — `DX improvements`, `review-skill polish`, `test-suite health`
- **Path** — `plugins/flow-next/skills/` (ideate inside a subtree)
- **Constraint** — `quick wins under 200 LOC`, `minor-bump only`, `no new deps`
- **Volume hint** — `top 3` (exactly 3 survivors), `50 ideas` (generate ≥50), `raise the bar` (60-70% rejection target)

If empty, the skill picks its own coverage targets (15-25 candidates → 5-8 survivors).

## Ralph-block (R8)

`/flow-next:prospect` is exploratory and human-in-the-loop. Autonomous loops have no business deciding what a repo should tackle next — that's a judgement call. Hard-error with exit 2 when running under Ralph.

```bash
if [[ -n "${REVIEW_RECEIPT_PATH:-}" || "${FLOW_RALPH:-}" == "1" ]]; then
  echo "Error: /flow-next:prospect requires a user at the terminal; not compatible with Ralph mode (REVIEW_RECEIPT_PATH or FLOW_RALPH detected)." >&2
  exit 2
fi
```

No env-var opt-in. Ralph never decides direction.

## Workflow

Execute the phases in [workflow.md](workflow.md) in order:

0. **Resume check** — list active artifacts <30d; ask extend / fresh / open via blocking question. Corrupt artifacts surfaced but never offered for extension.
1. **Ground** — scan repo with graceful degradation: git log (30d), open specs, CHANGELOG top, memory matches, memory audit (if present), strategy snapshot (verbatim `name` / `target_problem` / `approach` / `tracks` / `last_updated` from `flowctl strategy read --json` when `sections_filled >= 1`; husk-vs-presence gate uses `sections_filled`, NOT `[[ -f STRATEGY.md ]]`). Emit a structured 30-50 line snapshot — titles + tags only, never raw bodies.
2. **Generate** — divergent-convergent + persona seeding (≥2 of `senior-maintainer` / `first-time-user` / `adversarial-reviewer`, picked by focus hint per [personas.md](personas.md)). One divergent prompt; no self-judging.
3. **Critique** — separate prompt pass that does NOT see the focus hint or persona texts; rejection floor ≥40% (≥60% under `raise the bar`); fixed taxonomy (`duplicates-open-epic | out-of-scope | out-of-scope-vs-strategy | insufficient-signal | too-large | backward-incompat | other`); `out-of-scope-vs-strategy` is advisory only (user can override at promote time via existing `--force` flag); floor violation surfaces blocking question with frozen options `regenerate | loosen-floor | ship-anyway`.
4. **Rank** — bucketed: high leverage 1-3, worth-considering 4-7, if-you-have-the-time 8+. Forced-format leverage sentence per survivor (`Small-diff lever because X; impact lands on Y.`); no numeric scores.
5. **Write artifact** — atomic write-then-rename to `.flow/prospects/<slug>-<date>.md` via `flowctl.write_prospect_artifact`. Same-day collisions suffix with `-2`, `-3`. Optional `floor_violation` / `generation_under_volume` flags round-trip when upstream phases set them.
6. **Handoff** - blocking prompt for promote / chart (only if still singular+oversized+unclear) / interview / skip via the platform's question tool; frozen numbered-options fallback when no blocking tool is available.

Phases 0-6 are implemented. Promote command + list/read/archive land in tasks 4-5.

## Forbidden

- Running under Ralph — hard-block via the guard above.
- Setting `context: fork` — blocking question tools must stay reachable.
- Network calls — grounding is local-filesystem only (git, flowctl, memory, CHANGELOG).
- Writing to `.flow/specs/` directly — only `flowctl prospect promote` may do that.
- Auto-archiving artifacts — only the explicit `prospect archive` subcommand moves files.
- Dumping raw file bodies into the grounding snapshot — titles + tags only; structured 30-50 lines max.
