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 5.1 | $0.00032 | $0.00258 |
| Opus 5.5 | $0.00013 | $0.00103 |
| Sonnet 5.5 | $0.00006 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
agent-task-shaping 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 1mo 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
Agent Task Shaping
Use this skill before launching an agentic implementation, research, review, or long-running workflow from a vague request.
Process
- State the user-visible outcome in one sentence.
- Name the smallest reversible slice that can produce evidence.
- Separate required context from optional background.
- Choose the agent loadout or role that can own the slice end to end.
- Identify allowed tools, blocked tools, and any permission expansion that needs approval.
- Define the autonomy level: act directly, ask before mutation, ask before external side effects, or propose only.
- Define verification evidence before work starts.

Avoid
- turning broad strategy into unbounded execution
- starting from tool availability instead of task outcome
- asking a human for decisions the agent can resolve from repository evidence
- adopting learnings without a traceable issue, test, policy check, or run receipt
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.

agent-task-shaping is a skill published in the GitHub repository 45ck/skill-harness (15 stars, last pushed 4mo ago), licensed MIT. It adds 32 tokens to every session and 258 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other skills, from other repositories
harness-init-runner
Initialize a lightweight repo-local Node.js harness (harness/ + .harness/) WITHOUT AIOS dependency. Use ONLY when you need a standalone, portable harness. If AIOS is installed, use aios-long-running-harness instead — it has rex Command hosting, ContextDB integration, and checkpoint recovery.
do-it-audit
Use when the user explicitly requests a deep repository or scoped audit; not for ordinary diff review.
do-it-skill-authoring
Use when creating or revising a do-it skill, its description, references, or specialist delegation guidance so it adds needed judgment without prescribing ceremony.
do-it-review
Use to assess requirements and implementation quality independently, or to resolve a batch of review findings.
do-it-architecture
Use when authority, ownership, contracts, dependency boundaries, migration, recovery, or structural deletion can change a design.
do-it-code-quality
Use when designing, changing, or debugging code to locate causal ownership and close the affected behavior.
