tweakidea CLAUDE.md

tweakidea CLAUDE.md is an instructions file for coding agents from eph5xx/tweakidea. It costs 840 tokens per session, scanned A, original, MIT.

A set of Claude Code instructions for TweakIdea, a tool for examining startup problems and finding product opportunities. The instructions describe its commands, project decisions, development process, and rules.

In plain words
What is it for?
Use it while developing or operating TweakIdea, including its Hacker News research, idea evaluation, report comparison, and sharing commands.
Why use it?
It gives Claude Code the project context needed to follow TweakIdea's intended workflow and constraints. The input does not describe any separate feature beyond these instructions.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

tweakidea CLAUDE.md 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 4d 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.

Project

TweakIdea

A Claude Code skillset (slash commands + subagent definitions) that helps founders evaluate startup problems and discover product opportunities. Eight commands: /tweak:browse-hn searches HN via Algolia and ranks candidate threads to feed into /tweak:analyze-hn-post; /tweak:analyze-hn-post analyzes a single Hacker News discussion to identify technology shifts and surface product ideas; /tweak:evaluate runs 14 independent subagents to produce a weighted scorecard with assumption tracking; /tweak:improve reads a completed run and generates three concrete idea tweaks (small reframe, medium reshape, big reimagine) grounded in scoring rubrics; /tweak:diff compares two evaluation runs side-by-side showing score deltas, potential shifts, and per-dimension movers; /tweak:list and /tweak:show browse and open artifacts accumulated under ~/.tweakidea/; /tweak:share uploads a run's HTML report to a secret GitHub gist and returns a shareable rendered preview URL.

Core Value: Help founders make better decisions — evaluate whether a problem is worth solving, or discover what problems are emerging from technology shifts.

Constraints

  • Platform: Claude Code CLI — slash commands + agent definitions only. Exceptions: analyze-hn-post and browse-hn both shell out to uv + Python (hnparse.py and hnsearch.py) for HN fetching
  • Evaluation model: All 14 dimensions from EVALUATION.md must be covered, no skipping
  • Independence: Each subagent evaluates its dimension without seeing other dimensions' results
  • Clean context: Each evaluation run should be independent — no cross-contamination between runs
  • JSON contracts: All pipeline artifacts are typed JSON validated against schemas in schemas/. The orchestrator does zero text processing on agent output — all aggregation is in scripts/compute.py

Key Decisions

  • Founder data location: ~/.tweakidea/FOUNDER.md
  • Evaluator model: Sonnet (cost/speed balance for 14 parallel agents)
  • Narrative model: Opus (synthesis quality for cross-dimensional prose)
  • Researcher model: Sonnet (web research in Prepare stage)
  • Context isolation: FOUNDER.md passed ONLY to founder-market-fit evaluator; other 13 evaluators get EVALUATION_CONTEXT only
  • HN data location: ~/.tweakidea/hn/hn-{id}/
  • HN analysis model: Inline (no subagent — runs in command context)

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.
