session-log

session-log is a skill for Claude Code from Filip-Podstavec/claude-leverage. It costs 97 tokens per session (1,788 once invoked), scanned A, original, MIT.

A session-summary tool that records the important parts of a coding session in a dated Markdown file. It captures decisions, unfinished questions, and next steps for future agents or developers.

In plain words
What is it for?
Use it when wrapping up substantial work, especially after several commits. It creates or updates files in docs/sessions/ using a consistent format.
Why use it?
It prevents useful context from being lost in a long chat or having to be rediscovered later. The summary is shorter and more actionable than a full conversation transcript.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

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

session-log 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/session-log

What it does

At the end of a working session, writes a short distilled summary to docs/sessions/YYYY-MM-DD-<topic>.md following the standard template (context, what was done, key decisions, open questions, next steps, references). The next agent — yours tomorrow, or a different agent in a month — reads it to pick up the thread without re-discovering everything cold.

This is not a transcript dump. Raw chat is noise the next agent can't usefully consume. A session log is the distillate: 30–80 lines that compress a multi-hour conversation into actionable continuity.

Workflow

  1. Find target dir. Default docs/sessions/ from the current repo root (via git rev-parse --show-toplevel). If it doesn't exist, ask "create it now?" — if yes, create with a stub README.md describing the convention (mirror the one shipped with this plugin at docs/sessions/README.md).

  2. Get topic. If $ARGUMENTS has a positional, use it. Otherwise ask: "what was this session about, in one line?" Convert to kebab-case for the filename: 2026-05-24-pivot-cleanup.md.

  3. Compute filename. YYYY-MM-DD-<kebab-topic>.md. If a file with the same name exists (multiple sessions on the same topic same day), suffix with -2, -3, etc.

  4. Gather facts from git and the conversation:

    • Current branch: git rev-parse --abbrev-ref HEAD.
    • Recent commits this session: git log --oneline -10. Use the first commit hash after the previous session's HEAD if you can infer it, otherwise show the last 5–10 with the human confirming which ones belong.
    • Conversation summary: distill from the actual chat above (you, the model, have access). Categorize into:
      • What was done — concrete actions: code shipped, decisions recorded, files moved, skills added. Bullet list.
      • Key decisions — non-obvious calls made in conversation. Link to ADRs if applicable (suggest /adr-new for any decision likely to be re-litigated).
      • Open questions — anything deferred or unresolved.
      • Next steps — what should happen first in the next session.

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.
