diary is a skill for Claude Code, Codex from Snowflake-Labs/cocoplus. It costs 12 tokens per session (287 once invoked), scanned A, original, MIT.

A status command for CocoDiary, a work journal that records development sessions, decisions, and handoff notes.

In plain words
What is it for?
Use it to see the number of entries, the latest entry, open decisions, and recent handoff notes.
Why use it?
It gives a quick view of the project’s recorded history and unresolved decisions.

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

diary 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.

What it actually says

Your objective is to implement $diary.

Before proceeding, verify that .cocoplus/ exists. If not, output: "CocoPlus not initialized in this directory. Run $pod init to begin." Then stop.

Read .cocoplus/diary/ entries. Summarize entry count, latest entry, open decisions, and recent handoff notes.

Available subcommands: $diary view, $diary list, $diary search.

Anti-Rationalization

Shortcut / Temptation Why It Fails
Treat the skill as complete because the file exists Skill contracts must describe observable behavior and verification, not just command names.
Skip artifact and safety checks for a small command Small commands still mutate state or guide execution; preserve the same gates.

Exit Criteria

  • Command behavior matches the owning feature contract.
  • Required reads, writes, and user-visible outputs are described.
  • Safety, governance, and artifact constraints are preserved.
  • Missing state produces a clear, non-destructive result.
Changes

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.

diary is a skill published in the GitHub repository Snowflake-Labs/cocoplus (720 stars, last pushed 2d ago), licensed MIT. It adds 12 tokens to every session and 287 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 2026-09-03.
