planning

planning is a skill for Claude Code, Codex from LucasDuys/forge. It costs 22 tokens per session (1,663 once invoked), scanned A, original, MIT.

A planning tool that breaks an approved software specification into ordered work items, showing which tasks depend on others and which can be done in parallel. A dependency graph is a map of those relationships.

In plain words
What is it for?
Use it to create task frontiers, estimate token needs, connect tasks to repositories, and account for architecture, design, or repository-order constraints.
Why use it?
It turns a large approved plan into smaller, schedulable tasks and helps teams see the correct order of work.

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

planning 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 4d 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.

Planning Skill

This skill guides the decomposition of approved specifications into executable task frontiers. Each frontier is a dependency-ordered list of tasks grouped into parallelizable tiers.

Inputs

You will receive:

  • Spec files: One or more approved spec files from .forge/specs/
  • Depth: quick, standard, or thorough
  • Repo config: From .forge/config.json (may include multiple repos with ordering)
  • Capabilities: From .forge/capabilities.json (optional, informs task design)
  • Knowledge graph: graphify-out/graph.json (optional, enables architecture-aware decomposition)
  • Design system: DESIGN.md (optional, enables design-tagged UI tasks)

Procedure

Step 1: Read and Validate Specs

For each spec file in .forge/specs/ (or the filtered subset):

  1. Read the file and parse its YAML frontmatter
  2. Verify status: approved — skip any spec that is not approved
  3. Extract all R-numbered requirements and their acceptance criteria
  4. Note the linked_repos field — this determines which repos tasks will target
  5. Note the complexity field — this informs task sizing

Step 2: Determine Depth Parameters

Reference references/token-profiles.md for depth-specific settings:

Parameter Quick Standard Thorough
Tasks per spec 3-5 6-12 12-20
Tokens per task ~3k ~6k ~12k
Review steps None After critical tasks After every task
TDD enforcement No If skill available Always
Phase verification Skip Quick check Full goal-backward

Step 2.5: Load Architecture Context (optional)

Knowledge Graph: If graphify-out/graph.json exists, load it and extract:

  • God nodes (highest-connectivity concepts) for task prioritization
  • Community structure for aligning task boundaries with module boundaries
  • Cross-module dependencies for implicit dependency edges in the DAG

See skills/graphify-integration/SKILL.md for details.

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.

planning is a skill published in the GitHub repository LucasDuys/forge (55 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 1,663 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.
