write-daily-log

write-daily-log is a skill for Claude Code, Codex from RipeMangoBox/BITE. It costs 67 tokens per session (1,282 once invoked), scanned A, original, MIT.

A skill that creates or updates a structured daily research log from code changes, saved artifacts, and the conversation.

In plain words
What is it for?
Use it when writing a daily log, research summary, or progress update, including requests such as “写日志” or “日报.”
Why use it?
It turns scattered research evidence into a short record focused on decisions, reproducibility, results, and next actions.

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

write-daily-log 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 4d 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.

write-daily-log — Evidence-Driven Daily Research Log

Write a daily research log that captures facts which change future decisions, not a chronological activity dump.

Core Principle

Find evidence that changes future judgment → compress into log structure.

Only write content that satisfies at least one:

  • Changes route/decision
  • Changes experiment calibration or comparability
  • Affects reproducibility
  • Produces a concrete next action
  • Is the day's most important quantitative result

Trigger

  • User says "写日志", "日报", "write daily log", "update daily summary"
  • User specifies a target file (e.g. DailySummary/2026-04-15.md)
  • End of a long research session when user asks to wrap up

Procedure

Phase 1: Determine Target File

  1. If user specifies a file path → use it
  2. Else → DailySummary/<today's date>.md
  3. Read the target file if it exists; inherit its structure, tone, field names, and granularity
  4. If file doesn't exist → use TEMPLATE.md as skeleton

Phase 2: Collect Evidence

Evidence comes from two channels: conversation context and local persistent changes.

A. Conversation Context (current session)

Scan in priority order:

  1. User's explicit goals and requests this session
  2. Upper-level docs read this session (roadmap, experiment spec, prior summaries)
  3. New artifacts produced (eval yamls, metrics, new code, new docs)
  4. Key numbers verified or computed
  5. Engineering issues exposed or fixed
  6. Unresolved items and risks
B. Local Persistent Changes (cross-session)

Since the agent cannot access other sessions' history, use git and filesystem signals:

# 1. Find all git repos under the workspace
find <workspace_root> -maxdepth 3 -name ".git" -type d 2>/dev/null

# 2. For each repo, collect today's changes
git -C <repo> log --oneline --since="<today> 00:00" --until="<tomorrow> 00:00" --all
git -C <repo> diff --stat HEAD~5          # recent diff summary
git -C <repo> diff --name-only HEAD~5     # changed file list

# 3. Check uncommitted work
git -C <repo> status --short

# 4. Find today's new/modified artifacts
find <workspace_root> -name "*.yaml" -o -name "*.md" -o -name "*.csv" -o -name "*.log" | \
  xargs ls -lt 2>/dev/null | head -30

What ships with it

1 file 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.

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.

write-daily-log is a skill published in the GitHub repository RipeMangoBox/BITE (60 stars, last pushed 22d ago), licensed MIT. It adds 67 tokens to every session and 1,282 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 2026-08-30.
