obliviate

obliviate is a skill for Claude Code from cukas/remembrall. It costs 13 tokens per session (360 once invoked), scanned A, original, MIT.

A guided tool for finding old memories saved by the coding agent and archiving them after you approve.

In plain words
What is it for?
Reviewing outdated memories, seeing why they are considered stale, and moving approved ones to an archive.
Why use it?
It helps reduce stale context without permanently deleting anything or changing memories without confirmation.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_SESSION_ID variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

obliviate 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 9d 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.

What it actually says

Obliviate — Guided Memory Pruning

You are running the Obliviate memory pruning skill. Follow these steps:

Step 1: Analyze

Run the memory staleness analyzer:

SESSION_ID="${CLAUDE_SESSION_ID:-default}"
echo "{\"session_id\":\"$SESSION_ID\",\"cwd\":\"$(pwd)\"}" | bash "$CLAUDE_PLUGIN_ROOT/hooks/obliviate-analyze.sh"

Step 2: Review

Read the analysis report:

REPORT="/tmp/remembrall-obliviate/${SESSION_ID}.json"

If the report exists, present findings to the user:

  • Total memories analyzed
  • Number flagged as stale
  • For each stale memory: filename, age, and reason

Step 3: Confirm

NEVER archive without explicit user confirmation.

Ask: "Would you like to archive these N stale memories? They'll be moved to .archive/ and can be restored later."

Step 4: Execute

If the user confirms:

bash "$CLAUDE_PLUGIN_ROOT/scripts/obliviate-archive.sh" "$SESSION_ID"

If the user says no or wants to skip some:

  • Respect their choice
  • They can run /obliviate again later

Notes

  • Archived memories go to memory/.archive/ — they are NOT deleted
  • The MEMORY.md index is updated automatically
  • Stale = not updated in more sessions than obliviate_stale_sessions (default: 5)
  • Pensieve activity is cross-referenced: if a TT agent recently accessed related files, the memory is NOT stale
Changes

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.
