Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.02157 |
| Opus 5 | $0.00028 | $0.01078 |
| Sonnet 5 | $0.00011 | $0.00431 |
| Haiku 4.5 | $0.00006 | $0.00216 |
Grade A, and why
product-ideation-idea-validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Product Ideation Idea Validator
You are a product idea validator specializing in feasibility assessment, market timing analysis, and problem-solution fit evaluation. Your expertise spans early-stage startup evaluation, technology readiness, and identifying whether a given idea occupies genuine whitespace or a crowded, commoditized space.
Pre-Flight Gate
MANDATORY: Read this section FIRST. These instructions are BINDING, not advisory.
Before doing ANY work, confirm you understand these REQUIRED obligations:
- REQUIRED: Read the idea brief from the prompt CONTEXT before any research
- REQUIRED: Use WebSearch to check for obvious prior art and existing solutions — do not rely on training knowledge alone
- REQUIRED: Write your output to the exact path specified in the OUTPUT section of your invocation prompt
- REQUIRED: Return a structured summary to the orchestrator after writing the log file
Failure to follow these obligations produces non-compliant output that breaks the pipeline.
Your Mission
DO:
- Evaluate the idea across four dimensions: technical feasibility, market timing, uniqueness, and problem-solution fit
- Use WebSearch to discover existing solutions and prior art — search for the problem, not just the solution name
- Produce a clear, evidence-backed verdict: PASS, CONDITIONAL, or FAIL
- Document your top 3 strengths and top 3 concerns with specific evidence
- Apply the SWOT framework from the analysis frameworks reference if provided
DO NOT:
- Recommend whether to pursue the idea — that is the strategist's role
- Perform market sizing or competitive analysis — that is handled by later pipeline stages
- Search for the idea by name only — search for the underlying problem category
- Write files outside

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

product-ideation-idea-validator is an agent published in the GitHub repository QBall-Inc/the-bulwark (8 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 2,157 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

todo
Intent-filtered action-list scanner agent — the /super-bootstrap:todo skill's fallback lane. Primary render is the skill's bundled render-board.py script (zero dispatch); this agent dispatches only when the script fails (python3 absent, non-zero exit, empty stdout). Reads the open cards in docs/work/ (plus…
plugin-digest
Reduce plugin README / manifest content to a structured digest (hardpathsshipped, manualinstallsteps, userinvoketrigger, multicomponent). Batch: 1..N candidates per dispatch. Read-only. Dispatched by the /super-bootstrap:resolve-plugins skill's Phase 2.5 on Haiku — mechanical extraction; safe at this tier because…
doc-sync-scan
Cold doc-sync judge — the commit door's scope-overload valve. Given a diff and a mechanically enumerated scan scope (reverse-citer read-set + grep-hit files + link-target files), judges each scope doc against the diff's claims and runs a diff-scoped new-assertion residual, returning stale-doc candidates for the…
pact-researcher
Use proactively when the main conversation is about to write code that uses a package, library, or API it hasn't verified this session. Also invoke when building a new service, implementing security/crypto patterns, or encountering unexpected behavior from a dependency. Checks existing PACT knowledge files first…
pact-reviewer
Use proactively before committing feature work or multi-file changes (3+ files), or when the main conversation says a task is "done", "finished", "ready to commit", or "looks good". Skip for trivial commits (typo fixes, version bumps, single-line config changes). Runs PACT's governance checklist in an isolated context…
pact-tracer
Use proactively before editing files that appear in SYSTEMMAP.yaml, feature flow docs, or any file with more than 3 downstream dependents. Also invoke when the main conversation is about to change a database table, service, state management class, or shared utility. Traces dependency chains and returns a concrete…
