Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.01796 |
| Opus 5 | $0.00016 | $0.00898 |
| Sonnet 5 | $0.00006 | $0.00359 |
| Haiku 4.5 | $0.00003 | $0.00180 |
Grade A, and why
post-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 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 — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/asciinema-tools:post-session
Complete post-session workflow: finalize orphaned recordings → convert to text → AI-powered summarize.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Execution
Phase 1: Discovery
AskUserQuestion:
question: "What would you like to do?"
header: "Workflow"
options:
- label: "Quick analysis (Recommended)"
description: "Convert + keyword search + brief summary"
- label: "Full AI analysis"
description: "Convert + iterative AI deep-dive with guidance"
- label: "Complete workflow"
description: "Finalize orphans + convert + AI summarize"
- label: "Finalize only"
description: "Stop processes and push to orphan branch"
Phase 2: File Selection
If no file specified, discover available recordings:
/usr/bin/env bash << 'DISCOVER_EOF'
echo "=== Running asciinema processes ==="
ps aux | grep -E "asciinema rec" | grep -v grep | while read -r line; do
PID=$(echo "$line" | awk '{print $2}')
CAST=$(echo "$line" | grep -oE '[^ ]+\.cast' | head -1)
if [[ -n "$CAST" ]]; then
SIZE=$(ls -lh "$CAST" 2>/dev/null | awk '{print $5}' || echo "?")
echo " [RUNNING] PID $PID: $CAST ($SIZE)"
fi
done
echo ""
echo "=== Recent .cast files ==="

echo " $f ($SIZE, $MTIME)"

What ships with it
1 file 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.
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.

post-session is a skill published in the GitHub repository terrylica/cc-skills (62 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 1,796 once invoked, about $0.0002 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 2026-08-30.
