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

using-bdc 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 8d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

using-bdc

Orient a fresh session to the local BDC without becoming a broad automatic hook.

Do not wire this skill into UserPromptSubmit. Because: it is an orientation skill for choosing a BDC route, not a broad automatic hook.

Step 0: Escape Hatch

If builder says 别走流程, 直接做, 简单点, or 不走地图, do not route into the BDC map. Acknowledge once and do the smallest direct action.

Exception: do not bypass safety gates for destructive changes, secret access, public upload, deploy, database migration, force push, or irreversible writes.

Roadmap

/idea -> /plan -> /execute -> /verify -> /ship

Use ${BDC_HOME:-$HOME/.bdc}/standards/roadmap.md as the source of truth for the five-station map. /autoloop is an explicit automation wrapper, not a sixth station.

Use ${BDC_HOME:-$HOME/.bdc}/standards/route-intent.md as the source of truth for natural-language routing, escape directives, meta questions, and high-risk false-positive routes.

Route

User intent Route
Clarify a fuzzy idea before planning /idea
Need a written plan plan
Start executing an approved plan execute
Review completed work independently /verify
Decide whether work is ready to ship /ship
Explicitly automate an approved plan /autoloop
Continue from prior work pickup or handoff
Watch pull request or GitHub events watch-pr
Graph or query local knowledge Out of BDC core
Check BDC health /health or ${BDC_HOME:-$HOME/.bdc}/bin/bdc doctor
Need standards map ${BDC_HOME:-$HOME/.bdc}/standards/dispatch.md

Active plan check

If the user says "start", "开始", "go", or "执行", first check whether an active plan exists:

bash ${BDC_HOME:-$HOME/.bdc}/scripts/active-plan-resolver.sh --list

If exactly one active plan is selected, route to /execute. If multiple filesystem candidates appear, first resolve from current-session evidence: explicit plan path/name in the prompt, the plan just created/reviewed/approved in this session, a current-plan cursor if present, current repo target root, or a clear project/topic match. If one candidate is uniquely supported, route to /execute and state the reason. Do not ask builder solely because the resolver returned multiple stale active plans; ask only when no unique candidate remains after context resolution, or when the next action is destructive/irreversible.

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.
