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 | $0.00043 | $0.00807 |
| Opus 5 | $0.00022 | $0.00404 |
| Sonnet 5 | $0.00009 | $0.00161 |
| Haiku 4.5 | $0.00004 | $0.00081 |
Grade A, and why
whodb 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.

WhoDB Database Assistant
You have access to WhoDB for database operations. Use these tools and commands to help users with database tasks.
MCP Tools (Preferred)
When the WhoDB MCP server is available, use these tools directly:
whodb_connections
List all available database connections.
No parameters required.
Returns: List of connection names with type and source (env/saved).
whodb_query
Execute SQL queries against a database.
Parameters:
- connection: Connection name (optional if only one connection exists)
- query: SQL query to execute
Example: whodb_query(connection="mydb", query="SELECT * FROM users LIMIT 10")
whodb_schemas
List all schemas in a database.
Parameters:
- connection: Connection name (optional if only one connection exists)
Example: whodb_schemas(connection="mydb")
whodb_tables
List all tables in a schema.
Parameters:
- connection: Connection name (optional if only one connection exists)
- schema: Schema name (optional, uses default if not specified)
Example: whodb_tables(connection="mydb", schema="public")
whodb_columns
Describe columns in a table.
Parameters:
- connection: Connection name (optional if only one connection exists)
- table: Table name (required)
- schema: Schema name (optional)
Example: whodb_columns(connection="mydb", table="users")
CLI Commands (Fallback)
If MCP tools are unavailable, use the CLI directly via Bash:
Query Execution
whodb-cli query "SELECT * FROM users LIMIT 10" --connection mydb --format json
Schema Discovery
# List schemas
whodb-cli schemas --connection mydb --format json
# List tables
whodb-cli tables --connection mydb --schema public --format json
# Describe columns
whodb-cli columns --connection mydb --table users --format json
Connection Management
# List connections
whodb-cli connections list --format json
# Test connection
whodb-cli connections test mydb
# Add new connection (interactive)
whodb-cli connections add --name mydb --type Postgres --host localhost --database mydb
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.
- 9d ago First seen · 126 lines · 43 tokens per session scan A 266e2dc1ef5c
whodb is a skill published in the GitHub repository xiaoyuge886/aigc (197 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 807 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.
