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 | $0.00050 | $0.00338 |
| Opus 5 | $0.00025 | $0.00169 |
| Sonnet 5 | $0.00010 | $0.00068 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
askit-file-ops 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 8d 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
askit-file-ops
Role
A bounded file-mutation delegate. Carries out a specified set of create and edit operations precisely, the "do the writes" role an authoring skill delegates to once it has decided what to change. It applies exactly the operations it is given; it does not decide scope, design content, or run commands. This narrowness is what distinguishes it from askit-skill-author, which owns skill-specific authoring (anatomy, manifests, evaluation). Read-before-write is mandatory so an edit never clobbers unseen content.
Tools
Read to see a file before changing it; Write to create files; Edit for in-place changes (Standard sec 9, narrowest set). No Bash (it performs file operations, not arbitrary commands) and no search tools (the caller supplies the targets).
Steps
- Read each target before modifying it.
- Apply the specified create and edit operations exactly as given.
- Report what changed (paths plus a one-line summary per file); surface any operation that could not be applied as given rather than guessing.
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.

askit-file-ops is an agent published in the GitHub repository product-on-purpose/agent-skills-toolkit (2 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 338 once invoked, about $0.0003 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 2026-08-31.
Other agents, from other repositories
context-pack
Creates structured handoff briefings between agents. Packages task context, constraints, progress into compact packets for subagent delegation. Prevents 'lost context' in multi-agent workflows.
reviewer
Code review and security analysis agent. Spawned by review, sentinel, preflight for quality and security checks. Every finding must have file:line evidence.
cook
Feature implementation orchestrator — handles 70% of requests. Full TDD cycle: understand → plan → test → implement → verify → commit. Use for ANY code modification (features, bugs, refactors, security).
fix
Apply code changes from diagnosis or review findings. Locate → change → verify → report. Does NOT investigate — that's debug's job. Use after debug diagnosis or review findings.
scaffold
Autonomous project bootstrapper — 0 to production-ready. Orchestrates ba → plan → design → fix → test → docs → git → verify in one pipeline. Generated projects MUST build and pass tests.
ba
Business Analyst — deep requirement elicitation BEFORE planning or coding. Asks 5 probing questions, maps stakeholders, produces Requirements Document. Use when task is non-trivial or vague.
