multi-agent-collaboration-system: Skill for Claude Code

.agents/skills/record-session/SKILL.md

record-session is a skill for Claude Code, Codex from lxyer/multi-agent-collaboration-system. It costs 65 tokens per session (661 once invoked), scanned A, original, MIT.

A record-keeping step for completed Trellis coding sessions. It writes summaries, commit references, and developer-index updates to workspace journal files after a person has tested and committed the work.

In plain words
What is it for?
Use it after human testing and a code commit to archive completed tasks and add a session summary with the relevant commit hashes.
Why use it?
It preserves what was done so later sessions can recover the project's history and context. It also archives tasks that are actually finished.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is lxyer/multi-agent-collaboration-system's own configuration. It tells Claude Code and Codex how to work on multi-agent-collaboration-system itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything multi-agent-collaboration-system configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 ./.trellis/scripts/get_context.py --mode record.

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

record-session 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 5d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

[!] Prerequisite: This skill should only be used AFTER the human has tested and committed the code.

Do NOT run git commit directly — the scripts below handle their own commits for .trellis/ metadata. You only need to read git history (git log, git status, git diff) and run the Python scripts.


Record Work Progress

Step 1: Get Context & Check Tasks

python3 ./.trellis/scripts/get_context.py --mode record

[!] Archive tasks whose work is actually done — judge by work status, not the status field in task.json:

  • Code committed? → Archive it (don't wait for PR)
  • All acceptance criteria met? → Archive it
  • Don't skip archiving just because status still says planning or in_progress
python3 ./.trellis/scripts/task.py archive <task-name>

Step 2: One-Click Add Session

# Method 1: Simple parameters
python3 ./.trellis/scripts/add_session.py \
  --title "Session Title" \
  --commit "hash1,hash2" \
  --summary "Brief summary of what was done"

# Method 2: Pass detailed content via stdin
cat << 'EOF' | python3 ./.trellis/scripts/add_session.py --stdin --title "Title" --commit "hash"
| Feature | Description |
|---------|-------------|
| New API | Added user authentication endpoint |
| Frontend | Updated login form |

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.
