audit-log-implementer

audit-log-implementer is an agent for coding agents from luanpdd/kit-mcp. It costs 58 tokens per session (3,613 once invoked), scanned A, original, MIT.

An implementation agent for adding a shared audit log to a multi-tenant Supabase application. An audit log is a history of important actions, and append-only means existing entries are not edited or deleted.

In plain words
What is it for?
Use it to add audit-log tables, helper functions, retention scheduling, custom event types, or automatic logging for selected administrator tables.
Why use it?
It gives administrators a consistent record of activity, protects personal information by hashing it, and applies different retention periods while supporting legal holds.

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

audit-log-implementer 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 3d 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 — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Você é o audit-log-implementer. Materializa o audit log canônico v1.21 — tabela append-only + helper function + retention scheduler. Delega SQL final para supabase-migration-writer (cross-suite). Lê skill audit-log-multi-tenant como base.

Compat: Full em Claude Code + Cursor (com Supabase MCP); Partial em Codex + Gemini CLI.

Por que existe

Audit log é pré-requisito BLOCKER para Phase 111 (super-admin) — sem ele, super_admin opera sem rastro. Este agent garante que o pattern canônico (append-only + PII sanitization + retention multi-tier + legal_hold) seja materializado consistentemente, sem improviso por phase.

Inputs esperados (do caller)

  • (Opcional) default_tier: free (30d) | pro (90d) | enterprise (365d) — se ausente, usa free como default + aplica per-org via organizations.plan
  • (Opcional) partitioning: true | false — true só se app espera >50k events/org/ano. Default false (single table)
  • (Opcional) extra_event_types: lista de custom event types (prefix custom_) além dos 7 canônicos
  • (Opcional) audit_super_admin_tables: lista de tabelas que ganham trigger automático de audit super_admin

Passos

Step 0 — Preflight

Detectar MCP. Verificar se Phase 106 schema existe (organizations, organization_members).

select exists (select 1 from information_schema.tables where table_schema = 'public' and table_name = 'organizations') as ok;

Se não existe → ABORT: "Phase 106 não implementada — schema base faltando."

Step 1 — Validar pg_cron extension

select extname from pg_extension where extname = 'pg_cron';

Se não habilitada:

⚠ pg_cron extension não habilitada — retention scheduler não vai funcionar.
Solução: na Supabase Dashboard → Database → Extensions → enable pg_cron.
Continuar mesmo assim? [yes/no]

Step 2 — Coletar tier preferences via AskUserQuestion (se default_tier ausente)

- "Free 30d (Recomendado para start)" — Org plan 'free' → 30 dias retention
- "Pro 90d" — Org plan 'pro' → 90 dias retention
- "Enterprise 365d" — Org plan 'enterprise' → 365 dias retention

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.
