session-management

session-management is a skill for Claude Code, Codex from EndogenAI/dogma. It costs 134 tokens per session (5,009 once invoked), scanned A, original, Apache-2.0.

A session-lifecycle skill for AI coding agents. It defines how to keep a scratchpad, record session starts and summaries, manage context limits, and coordinate work across sessions.

In plain words
What is it for?
Use it when starting or closing an agent session, saving progress in the workspace's temporary notes, following phase gates, or preparing a handoff.
Why use it?
It reduces lost context and makes ongoing agent work easier to resume and review, especially when a session is interrupted or compressed.

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-management 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 4d 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.

Session Management

This skill enacts the Algorithms Before Tokens axiom from MANIFESTO.md by encoding the full session lifecycle as a deterministic procedure. Session management is governed by AGENTS.md § Agent Communication — every rule in this skill derives from that section. Read AGENTS.md before deviating from any step below.


1. File Structure

The scratchpad lives in .tmp/ at the workspace root. It is gitignored and never committed.

.tmp/
  <branch-slug>/          # branch name with / replaced by -
    _index.md             # one-line stubs of all closed sessions on this branch
    <YYYY-MM-DD>.md       # one file per session day — the active scratchpad

<branch-slug> examples:

  • Branch main.tmp/main/
  • Branch feat/agent-skills.tmp/feat-agent-skills/
  • Branch docs/update-guides.tmp/docs-update-guides/

The _index.md accumulates single-line stubs for every closed session on the branch. Future sessions read it for fast orientation without opening old files.


2. Session Start

Context Snapshot Before Reset

Before calling prune_scratchpad.py --init during error recovery, save a snapshot of the current context:

uv run python scripts/prune_scratchpad.py --snapshot

This saves .tmp/<branch>/<date>-snapshot.yaml containing: task_name, task_parameters, timestamp, and active scratchpad section.

After re-entry into the failed task's decision point, compare contexts:

uv run python scripts/compare_context_snapshot.py \
  --snapshot ".tmp/$(git branch --show-current | tr '/' '-')/$(date +%Y-%m-%d)-snapshot.yaml"

If equivalent: truedo not re-attempt. Escalate to user: "My context is identical to the failed attempt. New direction needed."

Encoding point: Research basis: docs/research/orchestrator-autopilot-failure.md § Recommendation 5. Scripts: scripts/prune_scratchpad.py --snapshot, scripts/compare_context_snapshot.py.

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.

session-management is a skill published in the GitHub repository EndogenAI/dogma (2 stars, last pushed 10d ago), licensed Apache-2.0. It adds 134 tokens to every session and 5,009 once invoked, about $0.0007 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.
