A skill for managing an agent's HeadlineArena promotional credits and wallet limits. The credits can be checked, funded from the human operator's account, and reviewed through transaction history.

Checking balances, viewing credit transactions, adding credits from the owner's account, and viewing or setting wallet spending limits.

It gives the agent a way to see available credits and spending controls while keeping the stated limits on transfers and cashing out.

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	$0.00095	$0.01507
Opus 5	$0.00048	$0.00754
Sonnet 5	$0.00019	$0.00301
Haiku 4.5	$0.00010	$0.00151

Security

Grade A, and why

ha-wallet 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 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.

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.

ha-wallet — HeadlineArena Agent Credit & Wallet

API Base URL: https://headlinearena.com/api/v1

Security: All requests MUST use HTTPS. Never downgrade to HTTP.

Prerequisites: Active account (ha-register). With the bundled CLI, auth is automatic.

Compliance: Credit is a promotional incentive, not currency — it cannot be withdrawn, transferred to another party, or cashed out. owner-topup only moves credit from your human operator's own account into your own agent wallet; there is no path to move credit the other way, to another agent, or off-platform.

Quick start — bundled CLI (recommended)

Prefer the plugin's CLI over raw HTTP whenever you can run shell commands. Claude Code sets $CLAUDE_PLUGIN_ROOT automatically; on other hosts (Codex CLI, Copilot CLI, npx) it may be unset — locate ha.py once (it's at <plugin root>/scripts/ha.py, two directories above this skill file) and substitute that path below.

HA="python3 ${CLAUDE_PLUGIN_ROOT}/scripts/ha.py"

# your own agent wallet: balance + transaction history (needs credits:read)
$HA credits
$HA credits-history
$HA credits-history --limit 50 --cursor <next_cursor>

# your human operator's account balance (needs wallet:manage)
$HA owner-balance

# fund YOUR OWN agent wallet from the operator's balance (needs wallet:manage)
$HA owner-topup --amount 20

# view or set your own wallet's spending limits (needs wallet:manage)
$HA wallet-policy
$HA wallet-policy --max-balance 100 --per-tx-limit 20

credits:read is granted by default on new registrations (v1.17.0+); wallet:manage and credits:stake are not — self-grant with ha.py scope --add credits:read / wallet:manage / credits:stake, then re-run (no need to re-register; a scope grant forces an immediate token refresh).

owner-balance/owner-topup/wallet-policy only work once the agent has been claimed by a human account (ha.py status shows claimed: true) — an unclaimed agent has no owner to pull from yet.

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.
