Lisa Project Ideation

Project Ideation

Generate persona-grounded, verifiable ideas for the host project in $ARGUMENTS (or the current working directory), then create PRDs for the selected build-ready ideas via lisa-research.

The value of this skill is grounding + filtering, not brainstorm volume. Ideas come from personas the project demonstrably serves, and an idea you cannot ground in obtainable data and cannot verify yourself is noise — demote it honestly.

Parameters

• target (first positional, optional) — a target project path, or an external product/site to draw inspiration from. Defaults to the current working directory.
• prd_ready=true|false (default false) — the PRD-lifecycle state for the PRDs this run creates. false → created in the source's draft state for human review. true → created prd-ready so the PRD side of lisa-intake auto-claims them. Passed straight through to lisa-research (which maps it to lisa-prd-source-write's initial_role) only after the PRD queue pressure gate allows auto-ready writes.
• max_prds=<n>|all (default 1) — how many build-ready ideas become PRDs this run. Default creates one PRD (the single top-ranked idea), because lisa-research is a heavy full flow. max_prds=3 creates the top three; max_prds=all creates one per build-ready idea. Discovery Spikes and Rejected ideas are never turned into PRDs regardless of max_prds.
• fixture=<path> (optional, verification-only) — a deterministic host-project fixture used for idempotency verification. When present, read the fixture before ranking and honor its declared single persona, single idea, existing-fit anchor, and expected dedupe marker. Do not use this parameter for normal ideation runs.

When to use

• "generate feature ideas for this project" / "what should this app do next?"
• "what should we build next for <persona / user type>?"
• "looking at <external product / website>, what should we add here?"
• "suggest practical improvements we can verify ourselves"

This skill does create PRDs (via lisa-research) for the selected ideas. It does not create tracker tickets (that is lisa-plan) and does not change code (that is lisa-implement).

Two gates every build-ready idea must pass

An idea may only become a Practical Idea (and thus a PRD candidate) if it passes BOTH gates. Otherwise demote it.

1. Practicality gate. The project can plausibly implement the idea from sources that actually exist: existing code, a data model, a route/command/UI surface, a public or integrated API, a scrapeable public page, an existing user input, a local database, or documented integrations. Name the specific source and how the data is obtained. "We could probably get the data somehow" fails.
2. Empirical verification gate. You can personally confirm the resulting behavior by using the software (running the CLI, hitting the API, loading the page, querying the DB, inspecting an artifact) and capture a concrete evidence artifact. "Tests could be written later" does NOT satisfy this gate — quality gates are prerequisites, never proof an idea works.

Failing the practicality gate → Rejected / Not Practical Yet (or Discovery Spike if a bounded probe could make it practical), naming the missing data/source/access. Failing only the verification gate → Discovery Spike (define the missing proof), never a build-ready recommendation.

Step 1 — Establish host-project context (always first)

Never propose ideas before you understand what exists. Inspect the host project and record:

• Project type and package manager — manifests (package.json, pyproject.toml, go.mod, Cargo.toml, Gemfile, …) and any .lisa.config.json.
• Docs and specs — README, docs/, wiki/, architecture notes, ADRs, marketing/landing copy.
• Current product surfaces or commands — routes, screens, CLI subcommands, API endpoints, scheduled jobs, generated artifacts.
• Data model and existing user inputs — schemas, migrations, forms, config the user supplies.
• Available data sources and ingestion/scraping paths — integrated APIs, public datasets, scrapeable pages, local databases, event streams.
• Existing verification tooling — how a human currently observes the software works.

Use Lisa's existing methodology rather than inventing a parallel flow. Route each evidence source through the matching established practice before any idea is promoted to Practical Ideas:

• Host-code inspection uses /lisa:codebase-research concepts: trace data flow from entry point to output, identify modification points, map dependencies, and find reusable code or patterns.
• Public, no-login comparison uses web/browser research when those tools are available: inspect the public surface, preserve source URLs, and separate observed behavior from inference.
• UI-facing recommendations use /lisa:product-walkthrough methodology first: inspect the current product surface, note existing-component reuse candidates, capture coverage smells or behavioral surprises, and only then list a UI idea as build-ready.

Step 2 — Derive the personas (evidence-gated, never invented)

Ideation is persona-driven, and the personas must be gleaned from the project itself — not assumed. Mine the Step 1 evidence for who the project actually serves:

• Docs / README / release notes / CHANGELOG — stated audiences, "for " framing, who each shipped feature was for.
• Code — auth roles / RBAC / permission checks, account-type or user-type enums, route guards, feature flags scoped to a cohort, role-specific UI branches.
• Data model — user / role / tenant / org tables, profile fields, subscription tiers.
• Tests & product walkthrough — the real user journeys exercised.
• External inspiration (Step 3, if used) — comparable products' user segments, as inspiration only.

Anti-fabrication rule (mechanical): no evidence citation → no persona. Generic roles ("admin", "analyst", "end user", "power user") are banned unless the project has specific evidence for them. Each persona requires at least two grounded signals from different source classes where available; if only one strong signal exists, emit a single low-confidence "Primary documented user" persona named as such — never fabricate a full set from thin evidence.

Cap the set at 3–6 personas (merge adjacent personas by goal/workflow; more than six is taxonomy noise). Each persona records:

• name — concrete and project-specific.
• goals — what this persona is trying to accomplish.
• pains — current friction for this persona, grounded in observed behavior/gaps.
• evidence — the specific files / doc sections / tables / releases that justify the persona.
• confidence — high | medium | low, with the reason.

Always emit a Personas Derived From Evidence section, even when no PRDs are created. Spikes and rejected ideas are still tagged with the persona they would serve (or cross-persona).

Step 3 — Optional external / public-source inspection

Only when the user references an external product, website, public dataset, or competitor:

• Inspect public, no-login surfaces only. Preserve every source URL so informed ideas cite it. The external source is inspiration, not a domain you bake in — keep the workflow reusable.
• If the runtime has no browser/web capability, mark that source unavailable and proceed with host-project-only ideas (document the fallback rather than fabricating findings).

Step 4 — Ideate per persona, then filter through the gates

For each derived persona, brainstorm ideas that serve that persona's goals/pains, tag each idea with the persona(s) it serves, then run every idea through BOTH gates. For each surviving idea, build a feasibility card:

• Persona(s) served — which derived persona(s), and why this matters to them.
• Existing fit — the current route / API / CLI / model / doc / surface it builds on (this is also the idea's stable "existing-fit anchor" used in the dedupe key).
• Data/source required + how it is obtained — the concrete accessible path.
• Known source limitations — rate limits, robots/ToS, staleness, missing fields.
• Smallest practical slice — the minimal useful version.
• Empirical verification steps — what you (the agent) will do against the running software.
• Evidence artifact — the screenshot, curl/CLI output, DB row, or generated file the verifier captures.
• Confidence — high | medium | low, with the reason.

Step 5 — Rank and select the PRD creation set

Rank Practical Ideas by persona value, feasibility, verification clarity, and project fit. Then select the creation set by max_prds (default 1 → the single top-ranked idea; <n> → top n; all → every Practical Idea). Spikes and Rejected ideas are reported but never selected.

Step 5.5 — Block auto-ready writes when the PRD queue has pressure

This step runs only when prd_ready=true. A draft run (prd_ready=false) skips this gate and continues to Step 6, because draft PRDs do not create immediate PRD-intake pickup pressure.

Before invoking lisa-research for any selected idea, inspect the configured PRD source queue with the same PRD reader contract used by /lisa:queue-status and evaluate it with evaluatePrdQueuePressure from plugins/lisa/scripts/queue-status-prd-readers.mjs (source: plugins/src/base/scripts/queue-status-prd-readers.mjs). Resolve the queue from .lisa.config.json the same way lisa-intake resolves the PRD side, and pass the matching queue argument in the blocked outcome (for example, github intake_mode=prd).

Queue pressure is any unresolved PRD lifecycle work that would make another auto-ready PRD compete with existing intake work. Treat at least these roles as pressure when the helper reports them: prd-ready, prd-in-review, prd-blocked, unresolved prd-ticketed, and source-reader failures or misconfiguration snapshots. prd-shipped / prd-verified terminal history is not pressure unless the reader helper explicitly reports it as unresolved.

If the helper returns allowed: false, stop before any lisa-research, lisa-prd-source-write, or vendor PRD writer invocation. Emit PRDs Created as a blocked outcome, not as an empty success or a silent idle run. The blocked outcome must include:

• source and tracker from .lisa.config.json;
• the decisive PRD lifecycle role;
• the blocking PRD item ref and url, when the snapshot supplies them;
• the smallest next action, preferring the helper's nextStep and otherwise using /lisa:intake <PRD queue>;
• a clear statement that no research or PRD source write was invoked.

Use this output shape so recurring automations can surface a useful next step without digging through debug logs:

## PRDs Created

Blocked: PRD queue pressure prevents auto-ready creation.
- source: <source>
- tracker: <tracker>
- role: <decisive role>
- item: <ref or "unavailable"> <url when available>
- next action: <helper nextStep or /lisa:intake <PRD queue>>
- write invoked: no

If the helper returns allowed: true, continue to Step 6 normally and keep the existing draft/ready creation behavior unchanged.

Step 6 — Create a PRD per selected idea (via lisa-research)

For each idea in the creation set, invoke /lisa:research with:

• the feasibility card and persona evidence as the problem statement (so the PRD inherits the grounding and the empirical verification plan),
• prd_ready (this run's flag — lisa-research maps it to draft vs prd-ready),
• a stable dedupe marker (see below) so a re-run references the existing PRD instead of creating a duplicate,
• a structured ideation_ledger_payload handoff containing the selected marker, automation id and memory path when available, persona names, persona evidence references, rejected overlap candidates, repo identity, prd_ready, selected idea title/key, and the expected empirical verification artifact. This payload is the only ideation-run metadata channel between project-ideation, research, prd-source-write, and the vendor writer; keep GitHub-specific rendering out of this skill.

lisa-research synthesizes the PRD and creates it in the configured source via lisa-prd-source-write. project-ideation never writes to the source directly — it delegates, so the PRD source stays switchable per project. Capture each returned PRD ref / URL / role / outcome.

Optional Codex automation memory

When the run has a Codex automation id or memory path, maintain a concise local advisory ledger after the PRD source write returns. Resolve the memory path in this order:

1. explicit memory_file=<path> or automation_memory=<path> argument, when supplied;
2. $CODEX_AUTOMATION_MEMORY, when set;
3. $CODEX_HOME/automations/<automation_id>/memory.md, when automation_id=<id> or $CODEX_AUTOMATION_ID is available.

Create the parent directory and memory.md if missing. Write one concise run entry keyed by the dedupe marker and run timestamp. The entry must include the marker, PRD URL/ref, outcome (created | reused | updated | blocked), lifecycle role (draft | ready | blocked or the returned source role), and source_agreement (github-source-wins, memory-created, memory-updated, or memory-missing-runtime). If memory says one thing but the PRD source search finds a matching open PRD, GitHub/source truth wins: reuse the source PRD and update memory rather than creating a duplicate. Keep memory advisory only; never use it to override lifecycle labels, source marker matches, or the PRD source writer's returned role. Do not store secrets, tokens, full PRD bodies, or private source excerpts in memory.

Dedupe marker (stable, never title-based)

Each created PRD carries the marker [lisa-project-ideation] idea=<stable-key>. Compute <stable-key> deterministically from: repo identity (configured repo or git remote + repo-root basename) + a normalized slug of the idea name + the normalized persona key(s) + the existing-fit anchor. Do not include rank, date, confidence, or the generated PRD title (they change across runs). lisa-prd-source-write searches the source for an open PRD carrying this marker before creating — matching by marker, never by title — so re-running ideation updates/references the existing PRD rather than duplicating it.

Step 7 — Output (no report file)

Emit two distinct in-session sections (do not write a report file):

1. Idea report (the audit trail):

   ## Personas Derived From Evidence
   - <name> — goals; pains; evidence (files/docs/tables/releases); confidence
   
   ## What Already Exists
   - <current surfaces, data, commands, workflows — so duplicates aren't re-proposed>
   
   ## Practical Ideas
   ### 1. <Idea name>  (persona: <persona(s)>)
   - Persona value · Existing fit · Data/source path · Practical slice · Empirical verification ·
     Evidence · Confidence
   
   ## Discovery Spikes
   - <ideas needing proof of data/access/verification — name the missing proof — tagged by persona>
   
   ## Rejected / Not Practical Yet
   - <attractive ideas rejected for missing data/access/legality/verification — name what's missing>
   

2. PRDs Created (the creation summary): for each selected idea — the created/reused PRD ref + URL, its lifecycle role (draft or ready), its dedupe marker, and created | reused. List the Practical Ideas that were not created this run and why (e.g. "below the max_prds=1 cut").

Always include the Personas, What Already Exists, Discovery Spikes, and Rejected sections (even if empty) so the user sees what was considered and filtered out.

Out of scope (hard rules)

• No fabricated personas. No evidence citation → no persona; generic roles banned without evidence (Step 2).
• No sign-in-only ideas unless the host project already supports sign-in and credentials are available. No private-data assumptions. No manual-data-only requirements unless the user accepts manual curation. No paid-API / non-scrapeable-source ideas in the build-ready list — demote with the blocker named.
• Tests, lint, typecheck, and build are not the empirical verification plan — they are prerequisites; verification must observe user-facing behavior.
• Do not create tracker tickets or mutate the host project's code. PRD creation (via lisa-research) is the only write this skill performs; ticket planning (lisa-plan) and implementation (lisa-implement) are separate, user-invoked flows.
• Do not write PRDs to the source directly — always go through lisa-research → lisa-prd-source-write so the source stays switchable.
• Do not add a new verification/browser-automation framework when one already exists — reuse it.
• Do not overfit to a source example. Keep the workflow project-agnostic.

Handing off

The created PRDs flow straight into the lifecycle:

• A draft PRD → a human reviews it, then promotes it to ready (or re-run with prd_ready=true).
• A prd-ready PRD → /lisa:intake (PRD side) auto-claims it → /lisa:plan decomposes it → /lisa:implement builds each item → /lisa:codify-verification locks in the verification.

Example outputs

Use the markdown examples in examples/ as shape references for the idea report:

• host-project-only.md — ideas grounded only in the current repository.
• public-external-inspiration.md — public, no-login external sources as inspiration, not hidden requirements.
• unavailable-data-rejection.md — naming missing private/paid/unavailable sources when demoting.
• evidence-card-format.md — the required evidence fields every Practical Idea card must carry.
• idempotency-verification-harness.md — deterministic fixture and script procedure proving that repeated prd_ready=true ideation keeps the open GitHub marker count at one, including the missing-memory rerun variant.
