session-memory-audit

session-memory-audit is a skill for Claude Code, Codex from apappascs/claude-code-sessions. It costs 93 tokens per session (965 once invoked), scanned A, original, MIT.

A health check for stored Claude Code memories, which are saved notes used to retain project context between sessions. It finds outdated notes, broken links, duplicates, missing details, and files that are not listed.

In plain words
What is it for?
Use it to review memory quality, find stale project notes, clean broken references, and synchronize memory files with their index.
Why use it?
It helps keep saved project knowledge accurate and prevents old or damaged notes from misleading future work. Some mechanical problems can be fixed automatically.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

session-memory-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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Step 1: Run the audit

bun run ${CLAUDE_PLUGIN_ROOT}/lib/memory-scanner.ts audit

Optional: --age-threshold N (default 60 days for staleness check)

Step 2: Present the summary

Show the health summary first:

Memory Health Report N memories across M projects N critical · N warnings · N info

Step 3: Present findings in two sections

IMPORTANT: Always separate findings into two clearly labeled groups.

Section A: Auto-fixable (deterministic, no AI)

These are safe, mechanical fixes. Present as a numbered table:

# Action File Project Issue

Where Action is one of:

  • DELETE — for expired findings (delete file + remove MEMORY.md entry)
  • REMOVE — for broken_link findings (remove dead entry from MEMORY.md)
  • INDEX — for orphan findings with frontmatter (add entry to MEMORY.md)
  • SYNC — for index_mismatch findings (update MEMORY.md description)

After the table, ask: "Apply all N auto-fixes? (yes/no)"

If yes:

  • For DELETE: Remove the file with rm, then edit MEMORY.md to remove the line referencing it
  • For REMOVE: Edit MEMORY.md to remove the broken link line
  • For INDEX: Read the file's frontmatter, append a new entry to MEMORY.md: - [name](filename.md) — description
  • For SYNC: Update the MEMORY.md entry's description to match the file's frontmatter description

Report each fix as it completes.

Section B: AI-assisted (requires analysis)

Present these AFTER auto-fixes are complete (or skipped):

"There are also N findings that require analysis to fix. Would you like to review them? (yes/no)"

If no — show summary and stop. Do NOT proceed with AI-assisted fixes.

If yes — walk through ONE AT A TIME:

For each finding, the ai_action field tells you what to do:

missing_frontmatter:

  1. Read the file content
  2. Infer the memory type from content (user bio = user, behavioral rule = feedback, project state = project, external pointers = reference)
  3. Infer a concise name and description
  4. Show the proposed frontmatter to the user
  5. If approved, prepend it to the file

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.

session-memory-audit is a skill published in the GitHub repository apappascs/claude-code-sessions (4 stars, last pushed 3mo ago), licensed MIT. It adds 93 tokens to every session and 965 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.
