add-todo

add-todo is a skill for Claude Code, Codex from kkollsga/codingest. It costs 123 tokens per session (1,454 once invoked), scanned A, original, MIT.

A workflow for recording future development work in a dev-docs backlog. Short links go in todos.md, while the full details go in a plans/ document.

In plain words
What is it for?
Use it to capture one-off tasks or split a larger audit, research report, code review or inbox message into actionable backlog items.
Why use it?
It keeps the backlog concise while preserving enough research or planning detail for the work to be understood later.

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

add-todo 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

add-todo

Capture work into the codingest dev-docs backlog the right way, respecting the convention:

todos.md holds one lean backlink line per thread; the detail lives in a plans/*.md file. Never put detail in todos.md; never leave a plans/ doc unlinked.

The whole point is to capture fast and scope well, so the item is actionable later without rediscovery. Do the work directly; only ask the user when a classification or scope decision is genuinely ambiguous.

This skill is the single authority on how a todo entry is shaped — classification, the lean-backlink format, detail-in-plans/, fix-site grounding. Other skills that file todos (e.g. read-inbox) follow the entry rules below rather than restating them.

Two modes

  • One-off — a single free-text item (/add-todo <description>). Run steps 1–6 below once.
  • Batch / deeper analysis — a body of findings (a research report, an audit, a code review, inbox content) that contains several actionable items. Decompose it first, then run the per-item logic for each. See §0 Decompose before the single-item steps.

0. Decompose (batch mode only)

When the input is analysis rather than one ask, first split it into discrete, independently actionable items — each a single change a future session could pick up alone. For the whole set, before filing:

  • Drop non-actionable material — background, confirmations, "no action" conclusions. A todo is something to do.
  • Group by theme. Items that share a subsystem go in one plans/ doc as sections (one backlink), not N scattered docs. Distinct threads get their own.
  • Dedup against the existing backlog — read todos.md first; fold an item that extends an existing thread into that thread instead of a new line.
  • Order by priority/effort so the backlink hooks read sensibly. Then run steps 2–5 for each resulting item (step 1's index read is done once). Keep the report (step 6) to the set: one line per filed entry.

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.

add-todo is a skill published in the GitHub repository kkollsga/codingest (0 stars, last pushed today), licensed MIT. It adds 123 tokens to every session and 1,454 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 2026-08-31.
