A way to resume long-running work from a project board that stores durable progress between sessions. It loads the relevant board and continues from its latest recorded context instead of rereading old chat transcripts.

Use it when starting work with an active board or when asked to warm-start, continue from the board, or pick up where previous work stopped.

It reduces catch-up time and preserves progress when work spans multiple sessions or agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.00574
Opus 5.5	$0.00035	$0.00230
Sonnet 5.5	$0.00017	$0.00115
Haiku 4.5	$0.00009	$0.00057

Security

Grade A, and why

warmstart scanned grade A with 1 finding 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.

What it actually says

resume — warm-start from a board

A previous session (possibly a different model or harness) left its durable context on a board. Your job: load it cheaply, then continue the work — not summarize it back to the user.

Steps

Find the board. If the user named a topic or context, open it directly (board_open or POST /board/open). Otherwise derive the project prefix from the git remote (repo:<host>/<owner>/<name>) and list its contexts — the prefix query is the project's context map:
```
curl -s 'localhost:4402/board?query=repo:<host>/<owner>/<name>'
```
(or board_list). Each row carries topic, description, and latest_seq. If there is exactly one board, use it. If there are several (repo:.../ctx:<slug> workstreams beside the project inbox), show the user a short menu — description + topic per line — and ask which context to resume; do not guess between active workstreams.
Catch up with one read. The default read is the warm start: latest digest + only the entries the digest does not cover:
```
curl -s 'localhost:4402/board/<id>?limit=1000'
```
Treat the digest as ground truth for everything before covers_seq; the uncovered entries are what happened since. Do NOT page through raw history (since_seq=0) unless a specific ambiguity forces you to — that re-spends exactly the tokens the digest saved.
Continue the work. The digest/entries should name a next action — start there. Briefly tell the user what state you resumed from (one or two sentences), then act. If the board is empty or has no next action, say so and ask for direction instead of guessing.
Close the loop. When you reach a milestone or the session winds down, post a checkpoint (see the checkpoint skill): conclusions, decisions with why, and the next action — so the board stays resumable for whoever comes after you.

Changes

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.

warmstart is a skill published in the GitHub repository chrzanowy/agent-tollbooth (0 stars, last pushed 2mo ago), licensed MIT. It adds 87 tokens to every session and 574 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
