start

start is a command for Claude Code from synaptiai/synapti-marketplace. It costs 29 tokens per session (12,288 once invoked), scanned A, original, Apache-2.0.

A workflow for starting development from a GitHub issue. It assigns the issue, creates a branch, breaks the acceptance criteria into tasks, and guides the implementation through verification.

In plain words
What is it for?
Use it to begin work on an issue, plan its tasks, implement the change on a branch, and verify each requirement.
Why use it?
It turns a broad issue into tracked work and keeps the implementation tied to the conditions that must be met.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions CLAUDE.md; names the AskUserQuestion tool; positional $N argument.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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.

Security

Grade A, and why

start 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 3d 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.

Required Skills

This command operates with these domain skills loaded:

  • llm-operator-principles — foundational operator stance: convergence = zero findings, in-PR fixes by default, no calendar-time estimates, narrow escalation triggers. MUST be consulted before any other phase
  • branch-and-task-management — branch creation, task decomposition
  • change-classification — change context awareness
  • capability-discovery — detect available quality tools
  • debugging-patterns — activates on-demand for ALL issues when any verification step fails (not gated on bug label)
  • preflight-checks — pure bash pre-flight validation (Phase 0)
  • criterion-verification-map — per-criterion evidence collection (Phase 2 + Phase 4)
  • holdout-validation — cross-reference self-review claims against file state (Phase 4)
  • issue-crafting — invoked when the issue body is missing acceptance criteria or needs reframing
  • specification-capture — capture non-goals, failure modes, and interface contracts to the decision journal (Phase 1, before Spec Validation Gate)

References

  • references/escalation-format.md — canonical six-field structure used by every Proactive-Autonomy escalation in this command (Spec Validation Gate, NEEDS-HUMAN-REVIEW verdict, visual verification BLOCKED, runtime verification skip request)
  • references/evidence-bundle-format.md — canonical bundle shape Phase 4 step 5 produces and Agent(verdict-judge) consumes

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.

start is a command published in the GitHub repository synaptiai/synapti-marketplace (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 29 tokens to every session and 12,288 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
