t2a-memory

t2a-memory is a skill for Codex from t2a-protocol/T2A. It costs 35 tokens per session (512 once invoked), scanned A, original, Apache-2.0.

A skill for installing and using T2A Memory, which stores user-level facts in local memory and passes work between T2A tasks. It includes validation, commit, status, and read steps for that memory workflow.

In plain words
What is it for?
Use it when installing T2A Memory, remembering a fact, resolving a memory handoff, validating a task, committing stored memory, or checking the current memory contents.
Why use it?
It provides a defined process for saving and checking memories without directly editing the memory files. It also explains how to continue when the usual T2A handoff tool is unavailable.

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

t2a-memory 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 1mo 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

T2A Memory

Instructions

Use this skill when the user asks you to install T2A Memory, remember a fact, or use user-level memory.

  1. Run {{T2A_MEMORY_BIN}} remember --memory-home {{MEMORY_HOME}} --tool-home {{TOOL_HOME}} "<fact>".
  2. Read the emitted t2a.handoff.
  3. Use the generic t2a skill if it is available to resolve the capsule.
  4. Fallback workflow: read task.json, prompt.md, input.json, and output.schema.json; write only output.json.
  5. Before commit, run core T2A validation and T2A Memory validation:
    • {{T2A_BIN}} validate "<task-dir>"
    • {{T2A_MEMORY_BIN}} validate --memory-home {{MEMORY_HOME}} --tool-home {{TOOL_HOME}} "<task-dir>"
  6. If both validations pass, run {{T2A_MEMORY_BIN}} commit --memory-home {{MEMORY_HOME}} --tool-home {{TOOL_HOME}} "<task-dir>".
  7. After commit, verify with {{T2A_MEMORY_BIN}} status --memory-home {{MEMORY_HOME}} and {{T2A_MEMORY_BIN}} read --memory-home {{MEMORY_HOME}}.
  8. Do not rerun {{T2A_MEMORY_BIN}} validate on the same already committed task as the normal close-out check.

Guidelines

  • Do not edit memory.json or MEMORY.md directly.
  • Do not use network access during memory handoff or consolidation.
  • Do not call LLM APIs or install LLM SDKs for this workflow.
  • Do not ask for model, base_url, api_key, provider settings, or vector database configuration.
  • Do not run git commit unless the user separately asks for a git commit.
  • t2a-memory commit commits to local memory files only. It is not git commit.

Examples

  • "Install T2A Memory for yourself and remember that T2A tools should not embed LLM API keys."
  • "Remember this preference in T2A Memory."
  • "Use T2A Memory to store this durable local-memory fact."

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.
