What is bk-credential?

A BlueKiwi tool for registering, updating, listing, and deleting service credentials such as API keys and access tokens.

Use it to add or manage credentials and control whether they are available only to you or shared with a group.

It keeps external-service secrets managed on the BlueKiwi server instead of repeatedly entering them into workflows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.01041
Opus 5.5	$0.00026	$0.00416
Sonnet 5.5	$0.00013	$0.00208
Haiku 4.5	$0.00007	$0.00104

Security

Grade A, and why

bk-credential 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 2mo 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Asking questions across runtimes: wherever this skill says AskUserQuestion, use your host runtime's native structured-question tool: AskUserQuestion (Claude Code), clarify (Hermes Agent), requestUserInput (Codex CLI), question (opencode). Always present the choices through that tool rather than plain prose. If the runtime has no such tool, list the options as numbered text and wait for the user's reply before proceeding.

BlueKiwi Credential Management

Securely manage external service credentials (API keys, tokens) on the BlueKiwi server.

Argument Handling

/bk-credential → Show action selection menu.
/bk-credential add <service name> → Start the add credential flow.
/bk-credential list → Show registered credentials list.

Security Principles

Credentials are scoped to the caller only by default. To share with a group, use the credential shares API or the credential management UI — credentials are no longer organised into folders.

Execution Steps

Step 0: Select Action

If no argument, ask via AskUserQuestion:

header: "Credentials"
options: ["List", "Add new", "Edit", "Delete"]

Action: List

Call list_credentials and display results:

Registered Credentials
━━━━━━━━━━━━━━━━━━━━━━━━━
ID  Service Name      Description
━━━━━━━━━━━━━━━━━━━━━━━━━
1   openai            OpenAI API
2   github            GitHub PAT
━━━━━━━━━━━━━━━━━━━━━━━━━
2 total

Action: Add New

Service name: Ask via AskUserQuestion.

Duplicate check: Call list_credentials and look for any existing entry with the same service_name (case-insensitive). The server doesn't enforce uniqueness, so duplicates are technically allowed but make later credential_id selection ambiguous (e.g. when bk-instruction binds a credential by service name). If a duplicate exists, ask via AskUserQuestion:

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.
