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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00113 | $0.01544 |
| Opus 5 | $0.00056 | $0.00772 |
| Sonnet 5 | $0.00023 | $0.00309 |
| Haiku 4.5 | $0.00011 | $0.00154 |
Grade A, and why
agent-deck 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.

Agent Deck
Terminal session manager for AI coding agents. Built with Go + Bubble Tea.
Version: 0.8.14 | Repo: github.com/asheshgoplani/agent-deck

# Launch TUI
agent-deck
# Create and start a session
agent-deck add -t "Project" -c claude /path/to/project
agent-deck session start "Project"
# Send message and get output
agent-deck session send "Project" "Analyze this codebase"
agent-deck session output "Project"
Essential Commands
| Command | Purpose |
|---|---|
agent-deck |
Launch interactive TUI |
agent-deck add -t "Name" -c claude /path |
Create session |
agent-deck session start/stop/restart <name> |
Control session |
agent-deck session send <name> "message" |
Send message |
agent-deck session output <name> |

agent-deck status |
Quick status summary |
Status: ● running | ◐ waiting | ○ idle | ✕ error
Sub-Agent Launch
Use when: User says "launch sub-agent", "create sub-agent", "spawn agent"
scripts/launch-subagent.sh "Title" "Prompt" [--mcp name] [--wait]
The script auto-detects current session/profile and creates a child session.
Retrieval Modes
| Mode | Command | Use When |
|---|---|---|
| Fire & forget | (no --wait) | Default. Tell user: "Ask me to check when ready" |
| On-demand | agent-deck session output "Title" |
User asks to check |
| Blocking | --wait flag |
Need immediate result |
Recommended MCPs
| Task Type | MCPs |
|---|---|
| Web research | exa, firecrawl |
| Code documentation | context7 |
| Complex reasoning | sequential-thinking |

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.
- 7d ago First seen · 187 lines · 113 tokens per session scan A bd4143bb603e
agent-deck is a skill published in the GitHub repository majiayu000/claude-skill-registry (600 stars, last pushed today), licensed MIT. It adds 113 tokens to every session and 1,544 once invoked, about $0.0006 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 2026-09-03.
