What it does

Claude Md Updater is an agent skill from jamditis/claude-skills-journalism. Scans the session for lessons and workflows, then proposes scoped CLAUDE.md edits. Use for save this lesson or add to context.

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Agent Workflows, covering Agent instruction files. The repository describes itself as: Claude Code skills for journalism, media, and academia - verification, FOIA, data journalism, academic writing, and more. The licence is MIT.

When your agent uses it

  • Save this lesson
  • Tasks that involve Agent instruction files

Example prompts

  • “Use the claude-md-updater skill to scan the session for lessons and workflows, then proposes scoped CLAUDE.md edits”
  • “/claude-md-updater”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Hard-won lessons
  2. New infrastructure
  3. New workflows
  4. Updated information

What it can do on your machine

Read from SKILL.md and the folder at commit e3e2172. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Claude Md Updater loads about 904 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 418 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~904

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

CLAUDE.md auto-updater

Analyze the current conversation to identify information worth persisting in CLAUDE.md for future sessions, then propose the edits for approval before writing anything.

What to look for

1. Hard-won lessons
  • Debugging sessions that revealed non-obvious causes
  • Workarounds for platform or tool limitations
  • Anti-patterns discovered through failure
  • "The real problem was..." moments
2. New infrastructure
  • New services deployed
  • New endpoints or URLs
  • New file paths or directories
  • New credentials or tokens (reference only, never the values)
3. New workflows
  • Commands that solve recurring problems
  • Multi-step processes that work well
  • Integration patterns between systems
4. Updated information
  • Changed ports, IPs, or URLs
  • New capabilities added to existing systems
  • Deprecated or removed features

Analysis process

  1. Scan the conversation for keywords:

    • "fixed", "solved", "the issue was", "turns out"
    • "deployed", "set up", "configured", "installed"
    • "new endpoint", "new service", "new path"
    • "doesn't work", "limitation", "workaround"
  2. Categorize findings. Only durable facts belong in CLAUDE.md:

    • Hard-won lessons go to the "Hard-won lessons" section
    • Infrastructure changes update the relevant section
    • New workflows go to the appropriate section
    • Transient, session-specific notes do not go in CLAUDE.md (see "What not to persist")
  3. Build the exact diff. Produce a unified diff against the current CLAUDE.md showing the precise lines and sections to be added or changed. This diff is what the user approves, not a summary of it.

  4. Present the diff for approval and write nothing until the user approves.

Output format

Show the exact patch first, then a short summary grouped by category:

## Proposed CLAUDE.md updates

```diff
--- a/CLAUDE.md
+++ b/CLAUDE.md
@@ section being changed @@
 existing context line
+new durable lesson, infra fact, or workflow
```

Summary of the diff above:
- Hard-won lessons: [one line, if any]
- Infrastructure updates: [one line, if any]
- New workflows: [one line, if any]

Apply this diff? Nothing is written until you approve.

What not to persist

CLAUDE.md is team-shared (checked into git) and advisory: it loads into every session, so it is for durable, infrequently-changing facts, not a running log. Per the project-memory skill, keep these out of CLAUDE.md:

  • Transient "what we did today" session summaries
  • Anything that changes frequently
  • Things Claude learns over time through corrections

Route those to auto memory (~/.claude/projects/<project>/memory/, which Claude maintains on its own) or to a gitignored CLAUDE.local.md for personal notes. Putting them in CLAUDE.md bloats shared context and loads stale per-session facts into future sessions.

Rules

  1. Never add sensitive values. Reference where a credential is stored; never include the actual token.
  2. Keep it concise. CLAUDE.md should stay scannable; target under 200 lines.
  3. Avoid duplication. Check whether the information already exists before adding it.
  4. Match the existing style. Follow the tone and format of the current file.
  5. Durable facts only. Persist hard-won lessons, infrastructure facts, and workflows. Session-specific notes belong in auto memory or a gitignored CLAUDE.local.md, never the committed CLAUDE.md.
