At a glance

Durable, access-scoped, append-only record of who changed what app data, when, and whether it was the agent or a human.

  • Adding an activity feed
  • SKILL.md covers Rule, Declare the target so it lands…, Defaults and how to override… and Who reads an event, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Declaring what a mutating action targets

What it does

Audit Log is an agent skill from BuilderIO/agent-native. Durable, access-scoped, append-only record of who changed what app data, when, and whether it was the agent or a human. Use when adding an activity feed or change history, declaring what a mutating action targets, auditing sensitive reads, or answering "what did the agent change / who edited this".

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • Adding an activity feed
  • Declaring what a mutating action targets
  • Auditing sensitive reads
  • Answering what did the agent change / who edited this

Example prompts

  • “what did the agent change / who edited this”
  • “/audit-log”

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Audit Log loads about 2k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 878 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 878 words (~1,974 tokens).

“Every mutating action automatically records an audit event — no wiring needed. The framework captures who/what/when/from-where at the defineAction seam, redacts credentials, and attributes the change to a human or the agent (with the agent thread/turn that caused it). You…”
