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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 37 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- high Tool Misuse · line 107 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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 | $0.00045 | $0.00962 |
| Opus 5 | $0.00023 | $0.00481 |
| Sonnet 5 | $0.00009 | $0.00192 |
| Haiku 4.5 | $0.00005 | $0.00096 |
Grade A, and why
bkend-auth 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.

MCP Auth Workflow
bkend MCP does NOT have dedicated auth tools. Use this workflow:
- Search docs:
search_docswith query "email signup" or "social login" - Get examples:
search_docswith query "auth code examples" - Generate code: AI generates REST API code based on search results
Searchable Auth Docs
| Doc ID | Content |
|---|---|
3_howto_implement_auth |
Signup, login, token management guide |
6_code_examples_auth |
Email, social, magic link code examples |
Key Pattern
User: "Add social login"
→ search_docs(query: "social login implementation")
→ Returns auth guide with REST API patterns
→ AI generates social login code
REST Auth API (Core Endpoints)
For the complete endpoint list, use search_docs or check Live Reference.
| Method | Endpoint | Description |
|---|---|---|
| POST | /v1/auth/email/signup | Sign up |
| POST | /v1/auth/email/signin | Sign in |
| GET | /v1/auth/me | Current user |
| POST | /v1/auth/refresh | Refresh token |
| POST | /v1/auth/signout | Sign out |
| GET/POST | /v1/auth/:provider/callback | Social login callback |
| POST | /v1/auth/password/reset/request | Password reset |
| POST | /v1/auth/password/reset/confirm | Confirm reset |
| POST | /v1/auth/password/change | Change password |
| GET | /v1/auth/sessions | List sessions |
| DELETE | /v1/auth/sessions/:sessionId | Remove session |
| DELETE | /v1/auth/withdraw | Delete account |
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.
- 8d ago First seen · 116 lines · 45 tokens per session scan A cf0b2d2b5466
bkend-auth is a skill published in the GitHub repository ww-w-ai/bkit-claude-code (595 stars, last pushed yesterday), licensed Apache-2.0. It adds 45 tokens to every session and 962 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 2026-08-30.
