feat(catalog): add Cost Tracker (cost) community extension by Quratulain-bilal · Pull Request #2448 · github/spec-kit

Quratulain-bilal · 2026-05-04T17:04:58Z

Summary

Adds a new community extension to the catalog: cost — Cost Tracker.

Track real LLM dollar cost across SDD workflows — per-feature budgets, per-integration comparison, and finance-ready exports. Token-analyzer counts tokens; this counts dollars, which is what finance, procurement, and engineering leads actually need to greenlight spec-driven development at scale.

Extension at a glance

Repo: https://github.com/Quratulain-bilal/spec-kit-cost
Release: v1.0.0 (tagged)
License: MIT
Commands (5): track, report, budget, compare, export
Hooks: none — purely user-invoked
Network: none — all data stays under .specify/cost/ locally
Compatible with: every integration (claude, copilot, gemini, opencode, …)

Why this is useful

Bundled pricing table covers Claude (Sonnet 4.6, Opus 4.7, Haiku 4.5), GPT-4o, and Gemini 2.5 Pro. Editable in cost-config.yml for negotiated rates.
Append-only JSONL ledger — diff-friendly, recoverable from a partial last line.
Budgets are versioned in config, so they're reviewed in PRs alongside other constraints.
compare re-prices the same workload across all models, so teams can quantify the savings (or cost) of switching integrations before they switch.

Catalog checklist

JSON valid (python -m json.tool)
Description under 200 chars
Required fields populated (name, id, description, author, version, download_url, repository, license, requires, provides, tags, created_at, updated_at)
HTTPS repository and download URLs
Tag v1.0.0 exists in the source repo
updated_at bumped at the top level
Alphabetical placement (between conduct and critique)

Test plan

Catalog JSON parses
Tag v1.0.0 resolves and the download URL returns 200
extension.yml validates against the extension schema
All five command files render as valid markdown with frontmatter

Thanks for reviewing!

Nice. There are some overlapping features between this and https://github.com/coderandhiker/spec-kit-token-analyzer ?
