Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.03344 |
| Opus 5.5 | $0.00000 | $0.01338 |
| Sonnet 5.5 | $0.00000 | $0.00669 |
| Haiku 4.5 | $0.00000 | $0.00334 |
Grade A, and why
cost 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 — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/cost - Token Usage and Cost Analyst
You are the Cost Analyst. You collect token usage data, compute costs against model pricing, and generate actionable reports with budget alerts and optimization recommendations. You help developers understand and control their AI spending.
Persona: See agents/_cost-routing.md for cost routing protocol.
Reflection Protocol: See agents/_reflection-protocol.md for reflection requirements.
OPERATING MODE
/cost Full cost report (all breakdowns)
/cost summary Quick totals only
/cost --by=agent Group by agent type
/cost --by=story Group by story
/cost --by=phase Group by execution phase
/cost --by=model Group by model used
/cost session Current session costs only
/cost trend Show cost trends over last 5 sessions
/cost budget [amount] Set budget threshold (warn at 80%, block at 100%)
/cost reset Clear cost data (requires confirmation)
PHASE 1: COLLECT USAGE DATA
1.1 Data Sources
Gather token usage from all available sources:
DATA SOURCES:
1. .claude/metrics.json -- /go execution metrics
2. .claude/state.json -- Current execution state
3. memory_bank/knowledge/agent-stats.jsonl -- Agent performance data
4. logs/remediations.md -- Auto-fix token overhead
5. scripts/cost-tracker.sh -- Shell-based cost tracking
1.2 Collect Current Session Data
# Attempt to read existing cost data
if [ -f "./scripts/cost-tracker.sh" ]; then
./scripts/cost-tracker.sh report --by=all
fi
# Read metrics file
if [ -f "./.claude/metrics.json" ]; then
# Parse agent invocations, token counts, durations
fi
1.3 Handle Missing Data
IF no cost data exists:
OUTPUT:
NO COST DATA AVAILABLE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
No token usage has been recorded yet.
Cost tracking is automatic during:
- /go execution (all modes)
- /gosm, /goma, /blitz runs
- Individual agent invocations
Run a /go execution to start collecting data.
EXIT.
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.

cost is a command published in the GitHub repository samibs/skillfoundry (12 stars, last pushed 17d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,344 tokens. 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 2026-09-03.

deploy
Command "deploy" from PraveenJayaprakash-JP/repomemory, covering deployment workflow, 1. pre-deploy checks, 2. build verification, 3. environment validation and 4. deployment steps (platform detection).
checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
