SkillSpector: 35 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00034 | $0.07929 |
| Opus 5 | $0.00017 | $0.03964 |
| Sonnet 5 | $0.00007 | $0.01586 |
| Haiku 4.5 | $0.00003 | $0.00793 |
Security
Grade A, and why
managing-sources 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 8d 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.

Managing Sources
Operational guide for managing changelog sources.
Tool Reference
Operations can be performed via CLI commands or typed MCP/agent tools. Use whichever interface is available in your context.
| Operation | CLI | Typed tool |
|---|---|---|
| List sources | releases list [slug] --json [--org <org>] [--query <text>] [--has-feed] [--category <c>] [--compact] [--limit <n>] [--page <n>] |
list_catalog (scoped by organization) or search with type: ["catalog"] for query-style lookup |
| Create source | releases admin source create <name> --url <url> [--type <type>] [--org <org>] [--feed-url <url>] [--primary] |
manage_source action "add" with name, url, type, organization, feed_url, is_primary (type auto-detected if omitted; only pass is_primary=true when the source is the org's primary changelog — see "Primary Sources") |
| Create App Store source | releases admin source create-appstore <url-or-id> [--platform ios|macos] [--org <slug>] [--product <slug>] [--storefront <code>] |
(no typed tool yet — CLI only) |
| Update source | releases admin source update <identifier> [--primary] [--priority <p>] |
manage_source action "edit" with identifier, is_primary, fetch_priority, name, url, type (use only when changing an already-added source; prefer setting flags on "add") |
| Delete source | releases admin source delete <slug> [--ignore --reason <reason>] |
manage_source action "remove" with identifier |
| Fetch releases | releases admin source fetch <slug> [--dry-run] [--max <n>] |
manage_source action "fetch" with identifier |
| Get latest releases | releases tail [slug] --json [--org <org>] |
get_latest_releases with source, organization, limit params |
| Search releases | releases search <query> --json |
search with type: ["releases"], query, limit |
| Evaluate URL | releases admin discovery evaluate <url> --json |
evaluate_url with url param (optional dry-run; manage_source action "add" auto-evaluates) |
| Create org | releases admin org create <name> [--domain <d>] [--description <t>] [--category <c>] [--tags <t1,t2>] |
manage_org action "add" with name, domain, description, category, tags |
| Update org | releases admin org update <slug> [--name <n>] [--domain <d>] [--tier <t>] [--billing-customer-id <id>] |
manage_org action "edit" with identifier, name, domain, description, category (--tier and --billing-customer-id are CLI-only; no typed-tool equivalent) |
| Get org | releases admin org get <slug> --json |
get_organization with identifier |
| Add tags to org | releases admin org tag add <slug> <tags...> |
manage_org action "tag_add" with identifier, tags |
| Link account | releases admin org link <slug> --platform <p> --handle <h> |
manage_org action "link_account" with identifier, platform, handle |
| Create product | releases admin product create <name> --org <org> [--category <c>] [--tags <t>] |
manage_product action "add" with name, organization, category, tags |
| Ignore URL | releases admin policy ignore add --org <org> <url> |
exclude_url action "ignore" with url, organization |
| Block URL | releases admin policy block add <url> |
exclude_url action "block" with url |
| Get playbook | releases admin playbook <org> |

manage_playbook action "update_notes" with organization, notes |
Changes
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.

managing-sources is a skill published in the GitHub repository buildinternet/releases (6 stars, last pushed 5d ago), licensed Apache-2.0. It adds 34 tokens to every session and 7,929 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
