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

publish-skills 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Build the request payload and POST to the registry Worker API. Use Python for the HTTP call (not curl/jq) to handle JSON encoding of SKILL.md content with special characters correctly.

When to use this skill

Use when the user wants to publish extracted or promoted skills to a Prism skill registry. Invoked as /publish-skills (Claude Code) or @publish-skills (Cursor), optionally with flags: --all (publish everything regardless of delta state) or --registry NAME (target a named registry).

Prerequisites

  • Skills must exist in _analysis/extracted_skills_codebase/ (created by /extract-skills (Claude Code) or @extract-skills (Cursor), or prism promote) and/or _analysis/extracted_skills_history/ (created by /run-history-pipeline (Claude Code) or @run-history-pipeline (Cursor))
  • Each skill directory must contain both plugin.json and SKILL.md
  • A registry must be configured in ~/.prism/registries.json (or legacy ~/.prism/config.json)
  • The REGISTRY_TOKEN environment variable or per-registry token in registries.json must be available

Flags

Flag Effect
--all Publish all valid skills, ignoring delta state (force republish)
--registry NAME Target a specific named registry from registries.json. If omitted, uses the default registry. The target must have writable: true.

Instructions

Step 1 -- Resolve target registry

Resolve the target registry from ~/.prism/registries.json (with fallback to legacy ~/.prism/config.json). If --registry NAME was specified, use that name; otherwise use the default registry.

python3 -c "
import json, os, sys
reg_path = os.path.expanduser('~/.prism/registries.json')
try:
    with open(reg_path) as f:
        data = json.load(f)
except (FileNotFoundError, json.JSONDecodeError):
    data = {'registries': [], 'default': None}
# Fall back to config.json migration
if not data.get('registries'):
    cfg_path = os.path.expanduser('~/.prism/config.json')
    try:
        with open(cfg_path) as f:
            cfg = json.load(f)
        url = cfg.get('registry_url', '')
        if url:
            print(json.dumps({'name': 'default', 'url': url, 'token': '', 'writable': True}))
            sys.exit(0)
    except: pass
    print('NOT_CONFIGURED')
    sys.exit(0)
# Resolve target: --registry NAME or default
target_name = None  # <-- set to registry name if --registry flag was provided
if target_name is None:
    target_name = data.get('default')
if not target_name:
    print('NO_DEFAULT')
    sys.exit(0)
for reg in data['registries']:
    if reg['name'] == target_name:
        if not reg.get('writable', True):
            print('READ_ONLY:' + target_name)
            sys.exit(0)
        print(json.dumps(reg))
        sys.exit(0)
print('NOT_FOUND:' + str(target_name))

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.
