memory-reflexion

memory-reflexion is a skill for Claude Code from rjmurillo/ai-agents. It costs 98 tokens per session (1,813 once invoked), scanned A, original, MIT.

A tool that turns a completed coding session log into a saved record of what was tried and what it cost. Later sessions can read these records to recall past work.

In plain words
What is it for?
Use it after a session to record the approach, results, and costs for future reference, or to recreate an existing episode record.
Why use it?
It prevents useful session outcomes from being lost when a conversation ends. It keeps the original episode record available without adding unused summaries.

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

memory-reflexion 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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (tests/__init__.py, tests/test_memory_reflexion_structure.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Memory Reflexion

Tier 2 episodic write operations: the reflexion write path extracted from the memory router per ADR-063 (memory-skill decomposition). memory still routes here; a caller that needs only to record a session outcome loads this sub-skill instead of the full memory surface.

Reflexion is one operation: extract an episode from a completed session log. The episode record is the durable artifact. It is committed to the repository and read directly by downstream consumers.

[!NOTE] This sub-skill previously carried a second step that folded episodes into a derived causal graph (Tier 3). ADR-089 removed that layer: nothing read it, and its aggregated output was noise. Episodes are unaffected and remain the system of record. See ADR-089 for the evidence.

Triggers

Use this skill when the user says:

  • extract episode from session to capture a completed session as an episode
  • record what happened this session for the reflexion write path
  • re-extract this episode to refresh a record over an existing episode file

Quick Start

# Extract an episode from a completed session log (Tier 2)
python3 .claude/skills/memory/scripts/extract_session_episode.py "<session-log-path>"

# Re-extract over an existing episode, merging rather than clobbering
python3 .claude/skills/memory/scripts/extract_session_episode.py "<session-log-path>" --preserve

The script is canonical and shared with the memory router; this sub-skill does not reimplement it. It lives at .claude/skills/memory/scripts/extract_session_episode.py.

Quick Reference

Operation Script Key Parameters
Extract episode (Tier 2) extract_session_episode.py session_log_path, --output-path, --force, --preserve

--force and --preserve are mutually exclusive. --force overwrites an existing episode file. --preserve merges a fresh extraction over the existing record without dropping richer data already there.

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.

memory-reflexion is a skill published in the GitHub repository rjmurillo/ai-agents (45 stars, last pushed yesterday), licensed MIT. It adds 98 tokens to every session and 1,813 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 2026-09-03.
