insert-phase

A command for adding urgent work between two existing roadmap phases using decimal numbers such as 72.1. A roadmap is a planned sequence of project work.

In plain words
What is it for?
Use it to insert an urgent phase, create its planning folder, update project state, and commit the roadmap change.
Why use it?
It preserves the existing phase order without renumbering all later phases when new work appears.

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

insert-phase 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.

What it actually says

Uses decimal numbering (72.1, 72.2, etc.) to preserve the logical sequence of planned phases while accommodating urgent insertions.

Purpose: Handle urgent work discovered during execution without renumbering entire roadmap.

@.planning/ROADMAP.md @.planning/STATE.md

Extract after-phase-number and description from $ARGUMENTS. Error if either is missing.

2. Calculate Decimal Phase Number

Find existing decimal phases after the target number to determine next available decimal (e.g., if 3.1 exists, use 3.2).

3. Generate Slug

SLUG=$(pbr-tools generate-slug "{description}")

4. Create Phase

pbr-tools roadmap insert-phase {after} --goal "{description}"

Create .planning/phases/{NN.D}-{slug}/ directory.

5. Update State

pbr-tools state record-activity "Inserted phase {NN.D}: {description}"

6. Commit

git add .planning/
git commit -m "docs: insert phase {NN.D} — {slug}"

7. Report

Display: "Phase {NN.D}: {description} inserted after phase {NN}." Suggest: /pbr:plan-phase {NN.D} as next step.

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.

insert-phase is a command published in the GitHub repository SienkLogic/plan-build-run (17 stars, last pushed 5mo ago), licensed MIT. It adds 18 tokens to every session and 395 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
