Getting it into your agent
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.

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 | $0.00110 | $0.02107 |
| Opus 5 | $0.00055 | $0.01053 |
| Sonnet 5 | $0.00022 | $0.00421 |
| Haiku 4.5 | $0.00011 | $0.00211 |
Grade A, and why
spec-write-tasks 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.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
spec-write-tasks
spec-write-tasks is an optional derived layer between spec-plan and spec-work. It does not execute code. It either compiles a settled source plan into a derived task pack, validates an existing task pack, or returns a no-task-pack decision.
It is a public workflow with the unified entrypoint spec-write-tasks.
Purpose
Decide whether a derived task pack is worthwhile, compile one when it reduces execution risk or context load, and validate existing task packs before they reach spec-work.
Workflow Contract Summary
When To Use
Use when a settled local source plan is too large or dependent for direct execution, when the user explicitly asks to split a plan into tasks, or when an existing local task pack needs validation before spec-work.
When Not To Use
Do not use for unresolved product or architecture scope, small changes that do not need a derived layer, remote repositories or package names, marketplace skill lookup, or implementation prompts that should go directly to spec-work.
Inputs
A local source plan path, existing task-pack path, or clear task-splitting request that resolves to one local source plan. Inputs must stay local and source-owned; remote repos, packages, marketplace identifiers, and generic task lists are rejected.
Outputs
One of: executable derived task pack, validated existing task-pack handoff, skip, return-to-plan, draft-only, or validate-only envelope. Task packs are derived execution indexes and never replace the source plan.
Artifacts
Executable task packs live under docs/tasks/ and must carry an artifact-root-relative POSIX source_plan, canonical source_plan_hash, generated_by: spec-write-tasks, mode: derived, and a valid Task Pack Contract JSON block. Executable identity is source-plan-path+body-hash; spec_id is an optional compatibility trace rather than a required identity field.
Failure Modes
Use machine-readable reason codes: source_plan_missing, ambiguous_plan, wrong_chain, stale_hash, unverifiable_hash, invalid_contract, repo_scope_missing, or scope_gap.
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.
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.

spec-write-tasks is a skill published in the GitHub repository ronronner02/codepilot-agent (0 stars, last pushed 3d ago), licensed MIT. It adds 110 tokens to every session and 2,107 once invoked, about $0.0006 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.
