It reduces the time spent re-reading a project after starting a new conversation or losing context.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/log-skill.sh "session-resume" "manual" "$$".

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-resume 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 7d 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.

What it actually says

Session Resume Skill

Helps agents quickly understand where work left off when starting a new session.

When To Use

  • At the start of any new conversation
  • When context seems missing
  • When user asks "what were we working on?"

Instrumentation

# Log usage when using this skill
./scripts/log-skill.sh "session-resume" "manual" "$$"

Quick Resume Checklist

1. Check Active Work

# Ready todos (highest priority)
ls todos/*-ready-*.md 2>/dev/null | head -5

# In-progress plans
ls plans/*.md 2>/dev/null

# Recent solutions (for context)
ls -t docs/solutions/**/*.md 2>/dev/null | head -3

2. Check Recent Git Activity

# Recent commits
git log --oneline -5

# Uncommitted changes
git status --short

3. Summarize Context

After gathering info, summarize:

4. Check System Health

./scripts/compound-dashboard.sh

Review health grade and recommendations before starting work.

5. Final Summary

📍 Session Context:

**Active Work:**
- {X} ready todos waiting
- Plan in progress: {plan name if any}

**Recent Activity:**
- Last commit: {subject}
- {Changed files if uncommitted}

**Suggested Next Steps:**
1. {Most logical next action}
2. {Alternative}

Automatic Triggers

Consider running this skill when you see:

  • User starts with "continue", "resume", "where were we"
  • First message in a new session
  • User seems to lack context

References

  • Todos: todos/
  • Plans: plans/
  • Solutions: docs/solutions/
  • Workflows: .agent/workflows/

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.
