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.

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 | $0.00009 | $0.00763 |
| Opus 5 | $0.00005 | $0.00381 |
| Sonnet 5 | $0.00002 | $0.00153 |
| Haiku 4.5 | $0.00001 | $0.00076 |
Grade A, and why
speckit.git.feature 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.
This is a copy
100% identical to speckit.git.feature — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Feature Branch
Create and switch to a new git feature branch for the given specification. This command handles branch creation only — the spec directory and files are created by the core /speckit.specify workflow.
User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Environment Variable Override
If the user explicitly provided GIT_BRANCH_NAME (e.g., via environment variable, argument, or in their request), pass it through to the script by setting the GIT_BRANCH_NAME environment variable before invoking the script. When GIT_BRANCH_NAME is set:
- The script uses the exact value as the branch name, bypassing all prefix/suffix generation
--short-name,--number, and--timestampflags are ignoredFEATURE_NUMis extracted from the name if it starts with a numeric prefix, otherwise set to the full branch name
Prerequisites
- Verify Git is available by running
git rev-parse --is-inside-work-tree 2>/dev/null - If Git is not available, warn the user and skip branch creation
Branch Numbering Mode
Determine the branch numbering strategy by checking configuration in this order:
- Check
.specify/extensions/git/git-config.ymlforbranch_numberingvalue - Check
.specify/init-options.jsonforbranch_numberingvalue (backward compatibility) - Default to
sequentialif neither exists
Execution
Generate a concise short name (2-4 words) for the branch:
- Analyze the feature description and extract the most meaningful keywords
- Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
- Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
Run the appropriate script based on your platform:
- Bash:
.specify/extensions/git/scripts/bash/create-new-feature.sh --json --short-name "<short-name>" "<feature description>" - Bash (timestamp):
.specify/extensions/git/scripts/bash/create-new-feature.sh --json --timestamp --short-name "<short-name>" "<feature description>" - PowerShell:
.specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -ShortName "<short-name>" "<feature description>" - PowerShell (timestamp):
.specify/extensions/git/scripts/powershell/create-new-feature.ps1 -Json -Timestamp -ShortName "<short-name>" "<feature description>"
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.git.feature is an agent published in the GitHub repository mick-gsk/drift (14 stars, last pushed 29d ago), licensed MIT. It adds 9 tokens to every session and 763 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to speckit.git.feature, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
Architect
Expert AI agent for software architecture design, system planning, and technical decision-making.
waves-controller
You are a wave execution orchestrator. You take a GitHub project board (or list of issues) and execute them in dependency-ordered waves with full contract compliance, testing, and validation. You coordinate all other Specflow agents through an 8-phase workflow.
pre-flight-simulator
You are a read-only simulation agent. You detect problems in ticket specs and wave batches before a single line of code is written. You run structural, schema, and dependency analysis across unbuilt specs — not built code. You return findings to the calling agent. You do not fix anything, write anything, or modify…
contract-test-generator
You are a Jest test generator for YAML contracts. You read docs/contracts/.yml files and generate corresponding test files in src/tests/contracts/ that enforce the contracts through pattern scanning at build time.
heal-loop
You are a self-healing fix agent for contract violations. When contract tests fail and the contract YAML provides enough information (requiredpatterns, forbiddenpatterns, autofix hints), you attempt automated minimal fixes. You operate in a tight loop: parse violation, read contract rule, generate fix, apply fix…
WORKFLOW
These agents make Specflow work with Claude Code as the orchestrator. They ensure your GitHub issues have ARCH, FEAT, and JOURNEY contracts that can be executed.
