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

trekker: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.

What it actually says

Begin working on a task by setting its status to in_progress.

IMPORTANT: /trekker:start is a skill (invoke via Skill tool), NOT a bash command. There is no trekker start CLI command. Use trekker task update as shown below.

Arguments

  • $1: Task ID (e.g., TREK-1) - optional

If no task ID provided:

  1. Show current in_progress tasks
  2. Show ready tasks (todo status)
  3. Ask which task to start

Execution

Step 1: Search for Related Work (MANDATORY)

Before starting ANY task, search for related context:

# Search for related past work using keywords from the task
trekker search "<task title keywords>"
trekker search "<related concepts>"

# Check completed tasks that might inform this work
trekker --toon task list --status completed

Why search first:

  • Past tasks may contain solutions you need
  • Reveals related work and file locations
  • Prevents re-doing solved problems
  • Prefer continuity over re-implementation

Step 2: Gather Full Context via CLI (MANDATORY)

# Show task details
trekker task show <task-id>

# View change history for this task
trekker history --entity <task-id>

# Get comments for context
trekker comment list <task-id>

# Check dependencies
trekker dep list <task-id>

Why this matters:

  • Understand previous work on this task
  • See if it was started/stopped before
  • Recall decisions and blockers from past sessions
  • If context is unclear: STOP → SEARCH MORE → RESUME

Step 3: Start the Task

# Set status to in_progress
trekker task update <task-id> -s in_progress

After Starting

Display a summary including:

  • Task title and description
  • Key points from history/comments
  • Related tasks found via search
  • Any dependencies or blockers

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.
