A planning workflow for creating, reviewing, or updating project plans and their supporting records.

Use it to create plan documents, record implementation evidence, define benchmarks, and report actual status.

It keeps plans, evidence, benchmarks, and status updates in a consistent structure so project progress is easier to track.

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	$0.00020	$0.02576
Opus 5	$0.00010	$0.01288
Sonnet 5	$0.00004	$0.00515
Haiku 4.5	$0.00002	$0.00258

Security

Grade A, and why

planner 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.

Planner With Anvien

Use this skill when work involves creating, reviewing, or updating a plan under docs/plans.

This skill is a workflow gate for plan/evidence/benchmark/actual-status authoring. It is not a command router. When a concrete Anvien command is needed for implementation evidence, choose it directly from the generated Command Selection Guide.

Standard Plan Set

A standard plan is a five-file set with the same date and slug:

docs/plans/YYYY-MM-DD-<slug>/
  YYYY-MM-DD-<slug>-plan.md
  YYYY-MM-DD-<slug>-rules.md
  YYYY-MM-DD-<slug>-evidence.md
  YYYY-MM-DD-<slug>-benchmark.md
  YYYY-MM-DD-<slug>-actual-status.md

Rules:

Put all five standard files in docs/plans/YYYY-MM-DD-<slug>/.
Use ISO date format: YYYY-MM-DD.
Use lowercase ASCII kebab-case for the slug.
Keep the same slug in all five standard files; only the suffix changes.
When writing a plan, you must follow the template exactly 100% (planner\templates\actual-status.template.md, planner\templates\benchmark.template.md, planner\templates\evidence.template.md, planner\templates\plan.template.md, planner\templates\rules.template.md).
Use the matching H1: Plan, Plan Rules, Evidence Ledger, Benchmark Ledger, or Actual Status.
Auxiliary files such as *-remaining-files.md can exist, but they are not part of the standard five-file set.

Template Files

Use the bundled templates before writing a new standard plan set:

templates/plan.template.md
templates/evidence.template.md
templates/benchmark.template.md
templates/actual-status.template.md

Rules:

Start from these templates instead of inferring structure from older nearby plans.
Read nearby plans only for local naming, scope, or evidence conventions that are clearly still active.
Replace template placeholders with the concrete date, slug, title, companion file paths, and task scope.
Keep template sections that protect discipline unless a user explicitly asks for a smaller review-only artifact.

What ships with it

4 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.

planner is a skill published in the GitHub repository tamnguyendinh/Anvien (9 stars, last pushed 2d ago), licensed MIT. It adds 20 tokens to every session and 2,576 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 2026-09-03.
