filesystem-truth-audit

filesystem-truth-audit is a skill for Claude Code, Codex from humanerd-drew/opencode-drewgent. It costs 0 tokens per session (1,481 once invoked), scanned A, original, MIT.

A procedure for checking whether files and folders mentioned in an agent’s memory or notes actually exist on disk.

In plain words
What is it for?
It helps audit completion claims, verify tool and script paths, and compare documented project state with the filesystem.
Why use it?
It catches outdated or false claims after files are moved, renamed, consolidated, or removed.

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

filesystem-truth-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.

Filesystem Truth Audit — Memory vs Reality 검증

memory/vault/위키에 적힌 "Done" 또는 "exists" 항목이 실제 filesystem에 존재하는지 검증하는 스킬. P0-brainstem filesystem_truth 강제.

Trigger

다음 중 하나:

  • memory에 있다고 했는데 실제로 없음 의심
  • root consolidation / source dir 이동 / rename 이후 검증
  • 새 skill/tool/script의 path를 memory에서 인용할 때
  • filesystem = truth 점검 요청

Procedure

Step 1: Claim 추출

memory/vault에서 path claim 찾기:

grep -rn "Done" ~/.{{AGENT_NAME_LOWER}}/P0-brainstem ~/.{{AGENT_NAME_LOWER}}/P4-cortex ~/.{{AGENT_NAME_LOWER}}/P2-hippocampus 2>/dev/null | head -20
grep -rn "tools/.*\.py" ~/.{{AGENT_NAME_LOWER}}/P4-cortex/growth 2>/dev/null | head -10

"tools/{{AGENT_NAME_LOWER}}_kanban_db.py (Phase 1) Done" 같은 줄 추출.

Step 1b: Config value claim 추출

memory/vault에서 config value claim (config 변경 사실) 찾기:

# threshold 같은 config 변경 claim
grep -rn "threshold:" ~/.{{AGENT_NAME_LOWER}}/P4-cortex/growth 2>/dev/null | head -10
grep -rn "0.5 → 0.9\|0.5 -> 0.9" ~/.{{AGENT_NAME_LOWER}}/P4-cortex ~/.{{AGENT_NAME_LOWER}}/P6-prefrontal 2>/dev/null | head -10
grep -rn "applied\|patched\|configured" ~/.{{AGENT_NAME_LOWER}}/P4-cortex/growth 2>/dev/null | head -10

"compression.threshold: 0.5 → 0.9 (2026-05-21)" 같은 줄 추출.

Step 2: Real filesystem 검증

# 2a. 단일 path 직접 확인
test -f ~/.{{AGENT_NAME_LOWER}}/source/{{AGENT_NAME_LOWER}}-agent/tools/{{AGENT_NAME_LOWER}}_kanban_db.py && echo EXISTS || echo MISSING

# 2b. 이름으로 전체 검색
find ~/.{{AGENT_NAME_LOWER}} -name "{{AGENT_NAME_LOWER}}_kanban_db.py" -type f 2>/dev/null

# 2c. wildcard 패턴 검증
ls ~/.{{AGENT_NAME_LOWER}}/source/*/tools/*.py 2>/dev/null | wc -l

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.

filesystem-truth-audit is a skill published in the GitHub repository humanerd-drew/opencode-drewgent (2 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,481 tokens. 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 2026-09-03.
