feature-track-add

A command that starts a feature documentation record using a lowercase, hyphen-separated feature ID.

In plain words
What is it for?
Use it to create a feature folder and update the feature documentation index, or to run the existing feature-tracking command.
Why use it?
It gives each feature a consistent place for its requirements, API notes, plans, and archived material without replacing existing files.

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.

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

feature-track-add 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 yesterday.

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.

What it actually says

feature-track-add

Create a Feature Track entry for a feature.

Expected argument: a lowercase hyphen-case feature id, for example checkout.

Run:

python3 cli/feature_track.py add "$ARGUMENTS" --root .

If the CLI is not present, create docs/features/<feature-id>/README.md plus prd/, api/, plans/, and archive/, then add a row to docs/features/README.md. Do not overwrite existing files.

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.
