reflect

reflect is a skill for Claude Code, Codex from mp-web3/claude-starter-kit. It costs 46 tokens per session (1,878 once invoked), scanned A, original, MIT.

A workflow for reviewing a recent coding-agent session and recording useful lessons, such as corrections or user preferences, in the appropriate knowledge or rules file.

In plain words
What is it for?
Use it to analyze the latest session or a chosen date range or file, identify real learnings, and save them for future work.
Why use it?
It prevents important feedback from being lost after a session and separates lasting lessons from ordinary conversation.

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

reflect 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.

/reflect — Session Learning System

First: Read LEARNINGS.md (in this skill's directory) before proceeding.

You are running a 4-phase reflection workflow. Follow each phase in order.

Arguments: $ARGUMENTS


Phase 1: Extract

Run the extraction script to get candidate learnings from session JSONL.

python3 ~/claude-assistant/scripts/extract-learnings.py $ARGUMENTS

If $ARGUMENTS is empty, it analyzes the latest session. Pass --since YYYY-MM-DD or --file <path> to customize scope.

  • If no pairs found -- tell user "Nothing to reflect on" and stop
  • If pairs found -- capture the output and proceed to Phase 2

Phase 2: Analyze

For each candidate pair from Phase 1, determine:

  1. Is this a real learning? ~40% are normal conversation — skip those. Look for:

    • Corrections ("no, do X instead", "actually...", "wrong")
    • Preferences ("always use...", "I prefer...", "from now on...")
    • Tool rejections with feedback (user denied + said why)
    • Workflow patterns (user repeatedly does something a specific way)
    • Implicit feedback (user rephrases, asks again, provides what Claude should have known)
  2. Check rejections — Read ~/claude-assistant/knowledge/self/rejections.md. For each candidate:

    • If it matches a previously rejected learning (same topic + target file): skip silently. Note in output: "Skipped: matches rejected learning from [date]"
    • If it contradicts a previously rejected learning (opposite of what was rejected): flag as potential reversal — present to user with context from the rejection log
  3. Classify and route each real learning using the routing table below.

  4. Check for duplicates — Read the target file and verify the learning isn't already captured.

  5. Scan for contradictions — For each proposed change with a target file: a. Read the target file b. Read up to 5 related files: same directory + shared tags (YAML tags field) + wiki-linked files c. Scan for statements that directly contradict the proposed change d. If contradiction found, flag it for Phase 3 conflict resolution:

    CONFLICT with [file.md:line]:
      Existing: "[quoted text]"
      Proposed: "[new learning]"
    

    e. Update feedback counters — If the contradiction traces to a specific existing rule/learning entry, increment its harmful counter in ~/claude-assistant/state/rule-feedback.json

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

reflect is a skill published in the GitHub repository mp-web3/claude-starter-kit (106 stars, last pushed 5mo ago), licensed MIT. It adds 46 tokens to every session and 1,878 once invoked, about $0.0002 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 2026-08-30.
