What is iikit-01-specify?

A guide that turns a natural-language feature idea into a feature specification. It produces user stories, Given/When/Then acceptance scenarios, functional requirements, success measures, and a quality checklist.

Use it to start or update feature specifications, write product requirements, define user stories and acceptance criteria, and check specification quality.

It helps clarify what a feature must do and how to judge whether it works before implementation begins.

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	$0.00071	$0.01426
Opus 5.5	$0.00028	$0.00570
Sonnet 5.5	$0.00014	$0.00285
Haiku 4.5	$0.00007	$0.00143

Security

Grade A, and why

iikit-01-specify 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 2mo ago.

The scan reads SKILL.md. This mod also ships 20 executable files (scripts/bash/common.sh, scripts/bash/create-new-feature.sh, scripts/bash/generate-dashboard-safe.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Intent Integrity Kit Specify

Process steps in order. Do not skip ahead.

Create or update a feature specification from a natural language description.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Constitution Loading

Load constitution per constitution-loading.md (soft mode — warn if missing, proceed without).

The text after /iikit-01-specify is the feature description.

Step 1 — Bug-Fix Intent Detection

Analyze the description using contextual analysis (not keyword-only) to determine primary intent: fix existing broken behavior vs. add new capability.

Bug-fix signals: "fix", "crash", "broken", "bug", "doesn't work", "fails", "error" — when describing broken existing behavior.
Not bug-fix: "Add error handling", "Implement crash recovery" — these describe new capabilities, not fixes.

If bug-fix intent is detected:

Display: "This sounds like a bug fix. Consider using /iikit-bugfix instead."
Show example: /iikit-bugfix '<the user description>'
Ask the user to confirm: proceed with specification (genuinely a new feature) or switch to /iikit-bugfix
User confirms new feature → proceed to Step 2; user wants bugfix → stop.

If bug-fix intent was NOT detected, or the user confirmed this is a new feature, proceed immediately to Step 2. If the user switched to /iikit-bugfix, finish here.

Step 2 — Generate Branch Name

Create 2-4 word action-noun name from description:

"I want to add user authentication" -> "user-auth"
"Implement OAuth2 integration for the API" -> "oauth2-api-integration"

Proceed immediately to Step 3.

Step 3 — Create Feature Branch and Directory

Check current branch. If on main/master/develop, suggest creating feature branch (default). If already on feature branch, suggest skipping.

Unix/macOS/Linux:

bash .tessl/plugins/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/bash/create-new-feature.sh --json "$ARGUMENTS" --short-name "your-short-name"
# Add --skip-branch if user declined branch creation

Windows (PowerShell):

pwsh .tessl/plugins/tessl-labs/intent-integrity-kit/skills/iikit-core/scripts/powershell/create-new-feature.ps1 -Json "$ARGUMENTS" -ShortName "your-short-name"
# Add -SkipBranch if user declined

What ships with it

28 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
