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	$0.00090	$0.01609
Opus 5	$0.00045	$0.00805
Sonnet 5	$0.00018	$0.00322
Haiku 4.5	$0.00009	$0.00161

Security

Grade A, and why

rollback 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.

Rollback Skill

User-invocable skill for checkpoint management and PDCA state rollback.

Arguments

Argument	Description	Example
(none)	List available checkpoints (same as `list`)	`/rollback`
`list`	List all available checkpoints	`/rollback list`
`to <checkpoint-id>`	Restore to a specific checkpoint	`/rollback to cp-1710842700000`
`phase`	Rollback to previous PDCA phase	`/rollback phase`
`reset <feature>`	Reset feature to initial (idle) state	`/rollback reset user-auth`

Action Details

list (Default)

List all available checkpoints for the current or specified feature.

Read checkpoint metadata from .bkit/checkpoints/
Filter by current active feature (or show all if no active feature)
Sort by timestamp (newest first)
Display formatted checkpoint list

Checkpoint Metadata Schema:

{
  "id": "cp-1710842700000",
  "feature": "user-auth",
  "phase": "design",
  "type": "auto",
  "timestamp": "2026-03-19T10:30:00.000Z",
  "description": "Auto-checkpoint before Do phase",
  "pdcaStatus": { "phase": "design", "matchRate": 0, "iterationCount": 0 },
  "files": ["docs/02-design/features/user-auth.design.md"]
}

Output Format:

--- Checkpoints: user-auth ------------------------
ID                    Phase    Type   Date                Description
cp-1710842700000      design   auto   2026-03-19 10:30   Before Do phase
cp-1710839100000      plan     auto   2026-03-19 09:25   Before Design phase
cp-1710835500000      idle     manual 2026-03-19 08:15   Manual save point
---------------------------------------------------
Total: 3 checkpoints

Usage: /rollback to cp-1710842700000

to

Restore state to a specific checkpoint.

Validate the checkpoint ID exists in .bkit/checkpoints/
Read the checkpoint metadata and saved state
Display what will be restored (phase, files, status)
Require user confirmation via AskUserQuestion (always, regardless of automation level)
On confirmation: a. Create a safety checkpoint of current state (before rollback) b. Restore pdca-status.json to the checkpoint's saved state c. Restore any saved file snapshots d. Write audit log: checkpoint_restored e. Display confirmation with restored state
On rejection: Cancel and display current state

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.
