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 | $0.00073 | $0.00668 |
| Opus 5.5 | $0.00029 | $0.00267 |
| Sonnet 5.5 | $0.00015 | $0.00134 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
trellis-start 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 1mo 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Start Session
Initialize a Trellis-managed development session. This platform has no session-start hook, so manually load the equivalent compact context by following these steps.
Step 1: Current state
Identity, git status, current task, active tasks, journal location.
python3 ./.trellis/scripts/get_context.py
If this output includes a line beginning Trellis update available:, copy the full line verbatim when summarizing session context. Do not shorten operational command hints.
Step 2: Workflow overview
Compact Phase Index, request triage rules, planning artifact contract, and the step-detail command.
python3 ./.trellis/scripts/get_context.py --mode phase
Full guide in .trellis/workflow.md (read on demand).
Step 3: Guideline indexes
Discover packages + spec layers, then read each relevant index file.
python3 ./.trellis/scripts/get_context.py --mode packages
cat .trellis/spec/guides/index.md
cat .trellis/spec/<package>/<layer>/index.md # for each relevant layer
Index files list the specific guideline docs to read when you actually start coding.
Step 4: Decide next action
From Step 1 you know the current task and status. Check the task directory:
- Active task status
planning+ noprd.md→ Phase 1.1. Load thetrellis-brainstormskill. - Active task status
planning+prd.mdexists → stay in Phase 1. Lightweight tasks can be PRD-only; complex tasks needdesign.md+implement.md. Load the relevant Phase 1 step detail beforetask.py start. - Active task status
in_progress→ Phase 2 step 2.1. Load the step detail:python3 ./.trellis/scripts/get_context.py --mode phase --step 2.1 --platform codex - No active task → classify first. For simple conversation / small task, ask only whether this turn should create a Trellis task. For complex work, ask whether you may create a Trellis task and enter planning. If the user says no, skip Trellis for this session.
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.

trellis-start is a skill published in the GitHub repository yuqie6/ProductFlow (307 stars, last pushed 18d ago), licensed MIT. It adds 73 tokens to every session and 668 once invoked, about $0.0003 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 2026-08-30.
