Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00025 | $0.00128 |
| Opus 5.5 | $0.00010 | $0.00051 |
| Sonnet 5.5 | $0.00005 | $0.00026 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
status scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Tandem Status
Run the status script and output the result. No preamble, no follow-up — just the script output.
CLAUDE_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT}" "${CLAUDE_PLUGIN_ROOT}/scripts/status.sh" "$(pwd)"
If rules files are missing, offer to re-provision by deleting ~/.tandem/.provisioned and restarting a session (ask first — user may have intentionally disabled a feature).
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.

status is a skill published in the GitHub repository jonny981/claude-tandem (5 stars, last pushed 6mo ago), licensed MIT. It adds 25 tokens to every session and 128 once invoked, about $0.0001 per session on Opus 5.5. 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.

assess
Issue triage and status assessment - analyze current state, detect health signals, and recommend next action with full workflow plan.
release
Automates the full release workflow: version bump, git tag, GitHub release, and npm publish.
solve
Deprecated: alias for /assess. Generate the recommended workflow for one or more GitHub issues.
token-efficiency
Always-on operational standard. Enforces concise responses, parallel tool execution, no redundant work, exploration tracking, and proactive context compression throughout every session. Applied automatically at session start.
time-awareness
Use when a claude-timestamp system reminder or Codex hook context says how long a turn has run, that a tool call was slow, or that a conversation or project is resumed after a gap; when the user asks how long something took, when they started, or where their time went; and before writing a date into notes, memory, a…
handoff
Write a continuation prompt for a fresh session into tmp/docs/ -handoff- .md, save state, and print the prompt so the user can clear the context window and continue the work elsewhere.
