reflect

reflect is a skill for Claude Code, Codex from rodrigo-kiko/claude-reflect-skill. It costs 68 tokens per session (994 once invoked), scanned A, original, MIT.

A session-review workflow that examines coding conversations for corrections, successful patterns, and preferences, then turns useful lessons into project knowledge in a CLAUDE.md file.

In plain words
What is it for?
It is for reviewing a development session, identifying lessons learned, and proposing updates to the project's CLAUDE.md instructions.
Why use it?
It helps preserve decisions and working preferences so the same mistakes are less likely to happen in later coding sessions.

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 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.

Reflect Skill - Session Analysis & Learning Extraction

This skill analyzes development conversations to extract actionable learnings that improve future coding sessions by updating the project's CLAUDE.md file.

Language Adaptation

Detect and match the user's working language for all outputs:

  • Session analysis reports
  • Learning descriptions
  • Proposed changes
  • Confirmation prompts

Keep technical terms (file paths, function names, code snippets) in their original form.

Core Workflow

Step 1: Scan Entire Conversation

Analyze the COMPLETE current conversation looking for signals. See references/signal-patterns.md for detailed patterns.

Primary signals to detect:

  1. Explicit Corrections → HIGH confidence

    • User says "No, don't do X" / "Use Y instead"
    • User states "Never/Always do X"
    • User explains why something was wrong
  2. Successful Patterns → MEDIUM confidence

    • Approaches that worked without objection
    • Code patterns user accepted
    • Structures repeated successfully
  3. Revealed Preferences → LOW confidence

    • Style choices (naming, comments, structure)
    • Communication preferences
    • Single observations needing validation

Step 2: Classify by Confidence Level

Apply criteria from references/confidence-levels.md:

  • HIGH: Direct, unambiguous corrections or rules from user
  • MEDIUM: Patterns that worked well, implicit preferences confirmed by acceptance
  • LOW: Single observations that need future validation

Step 3: Generate Analysis Report

Format output per references/output-format.md:

  1. Summary header with signal count
  2. Learnings grouped by confidence level
  3. Source reference for each learning
  4. Diff preview of proposed CLAUDE.md changes
  5. Action prompt for user approval

Step 4: Apply Changes (ONLY with explicit approval)

CRITICAL RULES:

  • NEVER modify any file without explicit user approval
  • Show EXACT diff of what will be added
  • Wait for user to type Y, N, or E
  • Preserve ALL existing content in CLAUDE.md

Files

What ships with it

3 files 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 rodrigo-kiko/claude-reflect-skill (2 stars, last pushed 8mo ago), licensed MIT. It adds 68 tokens to every session and 994 once invoked, about $0.0003 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.
