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 | $0.01182 | $0.01182 |
| Opus 5.5 | $0.00473 | $0.00473 |
| Sonnet 5.5 | $0.00236 | $0.00236 |
| Haiku 4.5 | $0.00118 | $0.00118 |
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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project
TweakIdea
A single skill, /tweakidea, in the Agent Skills format (tested on Claude Code, portable to other Agent Skills agents), that helps founders evaluate startup problems and discover product opportunities. Eight commands, invoked as /tweakidea <command>: /tweakidea browse-hn searches HN via Algolia and ranks candidate threads to feed into /tweakidea analyze-hn-post; /tweakidea analyze-hn-post analyzes a single Hacker News discussion to identify technology shifts and surface product ideas; /tweakidea evaluate runs 14 independent subagents to produce a weighted scorecard with assumption tracking; /tweakidea improve reads a completed run and generates three concrete idea tweaks (small reframe, medium reshape, big reimagine) grounded in scoring rubrics; /tweakidea diff compares two evaluation runs side-by-side showing score deltas, potential shifts, and per-dimension movers; /tweakidea list and /tweakidea show browse and open artifacts accumulated under ~/.tweakidea/; /tweakidea 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: Any Agent Skills-compatible agent, with Claude Code as the tested path — one skill (
skills/tweakidea/). Subagents are spawned as fresh-context agents (named by capability and model tier, mapped to Claude Code tools inreferences/runtime.md) that read their instructions fromreferences/agents/.evaluatestops on agents without subagents or web search/fetch. Python helpers inscripts/run throughuv - 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
skills/tweakidea/assets/schemas/. The orchestrator does zero text processing on agent output — all aggregation is inskills/tweakidea/scripts/compute.py
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.

tweakidea CLAUDE.md is an instructions file published in the GitHub repository eph5xx/tweakidea (55 stars, last pushed 2d ago), licensed MIT. It adds 1,182 tokens to every session, about $0.0047 per session on Opus 5.5. 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 2026-08-30.
