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

speckit-preset 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 2d 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.

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spec Kit — presets

Manage spec-kit presets with the Specify CLI specify preset command group. Presets bundle templates/configuration for a particular domain or workflow.

Prerequisite: needs the specify CLI. If specify --version fails, install it with the speckit-cli-setup skill first.

When to use

  • Find, install, or remove a preset.
  • Check which template a preset name resolves to.
  • Enable/disable a preset or adjust its resolution priority.

How to invoke

# Discover
specify preset list
specify preset search <query>
specify preset info <id>
specify preset resolve <name>          # show which template a name resolves to

# Install
specify preset add <id>
specify preset add --from <url>        # install from a ZIP URL
specify preset add --dev <path>        # install from a local directory
specify preset add <id> --priority <n> # lower number = higher precedence

# Lifecycle
specify preset enable <id>
specify preset disable <id>
specify preset set-priority <id> <n>
specify preset remove <id>

# Catalogs (sources presets are resolved from)
specify preset catalog list
specify preset catalog add <url> --name <name> [--install-allowed]
specify preset catalog remove <name>

Notes

  • Resolution priority: lower number = higher precedence (default 10).
  • Catalogs are added discovery-only by default. specify preset catalog add requires --name and defaults to --no-install-allowed; presets from a discovery-only catalog can be browsed but not installed (install errors with a "discovery-only" message). Pass --install-allowed to permit installs — only for catalogs you trust. The install_allowed policy lives in the consumer's .specify/preset-catalogs.yml, not in the catalog's own catalog.json.
  • A preset can also be installed at project creation: specify init <name> --integration copilot --integration-options="--skills" --script sh --preset <id> (use --script ps on Windows; see the speckit-init skill for the full OS-aware form and why --script is required).
  • Use specify preset resolve to debug unexpected template resolution.
  • Unlike extensions/bundles, specify preset add does not scaffold skills — a preset overrides the templates used to generate command content and is applied at init time. /skills reload only matters if a regeneration actually changes SKILL.md files under .github/skills/.

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.
