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 | $0.00038 | $0.00693 |
| Opus 5 | $0.00019 | $0.00347 |
| Sonnet 5 | $0.00008 | $0.00139 |
| Haiku 4.5 | $0.00004 | $0.00069 |
Grade A, and why
idea 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 9d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/idea — Clarify Before Planning
Step 0: Escape Hatch
If the user says 别走流程, 直接做, 简单点, or 不走地图, do not run /idea. Acknowledge once and do the smallest direct action.
Exception: do not bypass safety gates for destructive, secret, public-upload, deploy, database, force-push, or irreversible work.
Step 0.5: Project Goal Check
If PROJECT_GOAL.md exists in the current project root, read it before shaping the idea. If the request conflicts with current_phase, exit_criteria, or out_of_scope, stop and ask whether to update the goal or narrow the request. Do not edit PROJECT_GOAL.md automatically.
Contract
Create a one-page idea brief. Do not write an execution plan, do not edit code, and do not automatically continue to /plan.
Process
- Clarify the idea into:
- Problem
- User / Job
- Success signal
- Not Doing
- Open Questions
- Next:
/planor stop
- Save only if the user asks for a written brief. Use
${BDC_HOME:-$HOME/.bdc}/ideas/for shared ideas or projectdocs/ideas/when the project already has that convention.
Output
Keep the response short. The default output is the brief in chat, not a file.
Verification
- The output includes Problem, User / Job, Success signal, Not Doing, Open Questions, and Next.
- The output does not include implementation steps unless the user explicitly asks to continue to
/plan.
Red Flags
- The brief silently chooses scope for the owner.
- The response creates a plan or edits files without being asked.
PROJECT_GOAL.mdexists and was ignored.
Common Rationalizations
| Rationalization | Response |
|---|---|
| "The idea is clear enough; go straight to plan." | Do not skip clarification when the user invoked /idea. Incident: standards/skill-frontmatter.md cites trigger misuse as a known skill failure mode; /idea exists to avoid scope assumptions before /plan. |
| "I should write PROJECT_GOAL.md for the owner." | Do not edit it automatically. This is advisory from core/templates/PROJECT_GOAL.md: owner goals are owner-controlled. |
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.

idea is a skill published in the GitHub repository 0xmariowu/builders-dont-cry (4 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 693 once invoked, about $0.0002 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.
