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 | $0.00524 | $0.00524 |
| Opus 5.5 | $0.00210 | $0.00210 |
| Sonnet 5.5 | $0.00105 | $0.00105 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
opensea-skill AGENTS.md 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 2mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Reference docs and standalone `curl`/`jq` scripts per sub-skill. What it actually says
skill — Agent Conventions
Modular AI agent skills for interacting with OpenSea. Shell scripts, reference docs, and SKILL.md files for LLM consumption.
Quick commands
There is no build or test step. Validate shell scripts and docs manually.
# Syntax-check scripts (they live in per-domain subdirectories)
find . -name '*.sh' -exec bash -n {} +
# What CI runs: shellcheck, plus every opensea-*/scripts/*.sh must be executable
shellcheck $(find . -name '*.sh')
find . -name '*.sh' ! -perm -u+x
# Run the skill sync check
../../scripts/check-skill-sync.sh
Responsibilities
SKILL.mdrouter and five sub-skills:opensea-api,opensea-marketplace,opensea-swaps,opensea-wallet,opensea-tool-sdk.- Reference docs and standalone
curl/jqscripts per sub-skill. - Mirror
opensea-tool-sdk/topackages/tool-sdk/skill/.
Rules
- SKILL.md files are the source of truth for agents. Keep CLI commands, API endpoints, and shell script examples current.
- No duplication across sub-skills. Put wallet-provider tables in
opensea-wallet/and shared scripts inopensea-api/scripts/; link elsewhere. - Shell scripts are self-contained. Each script should work with
OPENSEA_API_KEYandcurl+jqonly. - Security. This package mirrors to a public repo; never include API keys, internal URLs, or private infra.
- Skill sync.
packages/tool-sdk/skill/andpackages/skill/opensea-tool-sdk/must remain identical. Runscripts/check-skill-sync.shlocally. - Releases.
/release skillis the full flow: bumppackage.jsonby hand, prependCHANGELOG.md, tagskill-vX.Y.Z, and let the GitHub/ClawHub chain publish. Do not runpnpm changesetfor skill — it is excluded from the pnpm workspace.
Conventions
- Shell scripts use
#!/usr/bin/env bashand readOPENSEA_API_KEY. - Scripts output JSON by default (pipe through
jqwhen available). - SKILL.md frontmatter declares env vars and dependencies.
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.
