github/spec-kit-copilot is a repository of GitHub Copilot integrations for Spec Kit, a toolkit for developing software through a structured specification-first workflow. It provides Copilot-specific commands, skills, canvases, and related workflow components for users of the Copilot CLI, Copilot App, and VS Code.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00108 | $0.00846 |
| Opus 5.5 | $0.00043 | $0.00338 |
| Sonnet 5.5 | $0.00022 | $0.00169 |
| Haiku 4.5 | $0.00011 | $0.00085 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 71 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
specifyCLI. Ifspecify --versionfails, 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 list --json # machine-readable installed inventory (CLI >= 1.0.7)
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). specify preset list --jsonrequires Specify CLI >= 1.0.7. It preserves CLI resolution order (highest precedence first) and returnsid,name,description,version, nullableauthor,priority,enabled, normalizedsource, andprovidescounts for commands, templates, and scripts.- Catalogs are added discovery-only by default.
specify preset catalog addrequires--nameand 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-allowedto permit installs — only for catalogs you trust. Theinstall_allowedpolicy lives in the consumer's.specify/preset-catalogs.yml, not in the catalog's owncatalog.json. - A preset can also be installed at project creation:
specify init <name> --integration copilot --integration-options="--skills" --script sh --preset <id>(use--script pson Windows; see the speckit-init skill for the full OS-aware form and why--scriptis required). - Use
specify preset resolveto debug unexpected template resolution. - Unlike extensions/bundles,
specify preset adddoes not scaffold skills — a preset overrides the templates used to generate command content and is applied at init time./skills reloadonly matters if a regeneration actually changesSKILL.mdfiles 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.

speckit-preset is a skill published in the GitHub repository github/spec-kit-copilot (18 stars, last pushed today), licensed MIT. It adds 108 tokens to every session and 846 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

brag-sheet
Turns vague "what did I do?" into evidence-backed impact statements for performance reviews, self-reviews, promotion packets, and weekly updates. Uniquely mines Copilot CLI session logs to reconstruct forgotten work, plus git commits and GitHub PRs. Enforces a 3-part impact contract (action → result → evidence). Works…
