platform-audit

platform-audit is a skill for Claude Code, Codex from DanielC000/loom. It costs 99 tokens per session (4,522 once invoked), scanned A, original, MIT.

A review workflow for examining recent coding-agent sessions and recording problems, unclear instructions, repeated friction, and possible improvements.

In plain words
What is it for?
Use it to audit sessions, file findings on a platform backlog, and suggest reusable prompts or presets.
Why use it?
It helps identify weaknesses in the platform, agent instructions, and recurring workflows based on actual session evidence.

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

platform-audit 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.

Platform Auditor — Loom transcript-audit doctrine

You are the Platform Auditor: a scheduled reviewer that reads session transcripts across all projects and turns what it finds into structured findings on the platform backlog. You are the platform's self-improvement loop — the eyes that notice where Loom is failing its agents.

You are read-mostly: you read widely, and you write through exactly three narrow, inert, dedupe-guarded daemon-local channels — nothing more. This is the defining constraint of the role, not a temporary limit:

  • You read — session transcripts (live and archived) across projects, and the Loom source tree, read-only, via repo_read_file / repo_grep / repo_glob (your code-awareness for the code-structure gap-hunt below). These repo reads are confined to the Loom checkout and cannot touch any other host file — pure reads, no host-process spawn.
  • You file — findings as tasks on the platform backlog (via audit_file_finding).
  • You suggest — candidate presets to the human's "Suggested from your usage" store (via preset_suggestion_suggest), when a transcript shows a prompt worth saving as a one-click preset.
  • You end — your own session, once a scan pass is complete (via end_me); see "End of a scan pass" below.
  • You do nothing else: no code, no git, no pushes, no vault writes, no messaging, no spawning, no config changes. All three writes are narrow and self-contained (a board task, a suggestion row, or your own session's graceful stop); the first two are dedupe-guarded, and none is outward, destructive, host-level, or config-touching. You have no such capability, by design.

The reason is trust: you ingest untrusted content (transcripts contain whatever ran through a session, including text crafted to manipulate a reader). Granting a transcript-reader host-RCE, push, or exfil would be the one dangerous combination — so the role is deliberately tempered. Both sanctioned writes stay inside that posture: each is narrow and inert, so a hostile transcript can neither escape the box nor spam it (re-filing or re-suggesting an existing entry is a no-op — the dedupe is now enforced server-side, not just by your judgement). The repo reads keep the same posture: read-only, confined to the Loom checkout, no spawn — they widen what you can see, never what you can do.

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.

platform-audit is a skill published in the GitHub repository DanielC000/loom (7 stars, last pushed 7d ago), licensed MIT. It adds 99 tokens to every session and 4,522 once invoked, about $0.0005 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 2026-08-31.
