read-context

read-context is a skill for Claude Code, Codex from odarino/haren. It costs 16 tokens per session (1,122 once invoked), scanned A, original, MIT.

A session-orientation workflow that reads a project’s manifest, progress records, artifact index, baseline documents, and Git state before work begins.

In plain words
What is it for?
Use it at the start of a session to understand project mode, modules, feature progress, available artifacts, and repository status.
Why use it?
It gives an agent a current view of the project and highlights missing documents, new files, invalid repository paths, or uncommitted changes.

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

read-context 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 7d 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.

Read Context

Orient yourself at the start of every session or before taking any action.

Process

  1. Read manifest.yaml

    • Project name, mode, repos, sources
    • Resolve each repo folder as in skill.md "Repos and Git". Warn if a folder is missing, and suggest haren init (it clones missing repos)

  2. Read progress.json

    • List all modules and their current status
    • List all features and their status within active modules

  3. Read artifact-index.md

    • Understand what artifacts exist
    • Note any gaps (e.g., module has no plan yet)

  4. Scan artifacts/00-baseline/

    • List any files found (PDFs, docs, markdown, etc.)
    • If files exist and mode is undecided: → Suggest switching to blueprint mode ("You have baseline docs — blueprint mode is recommended")
    • If files exist and mode is explore: → Suggest switching to blueprint mode ("Found docs in baseline — did you mean to use blueprint mode?")
    • If files exist and discovery hasn't started yet: → Suggest starting the discover phase to process them
    • If files were added since last session (compare against artifact-index.md): → Flag new documents and ask if the user wants to re-run or update discovery

  5. Git check — for each repo in manifest repos, and for the haren folder itself in the workspace layout (see skill.md "Repos and Git")

    • Check for uncommitted changes: git -C <repo> status --porcelain
    • Read the current branch: git -C <repo> branch --show-current
    • For each module with status implementing or evaluating that has lastCommit.<repoKey> for this repo: if the module branch does not exist in this repo, report "branch <branch> not found (merged or deleted?)" and skip the check for this repo. Else check that the recorded SHA is in the history with git -C <repo> merge-base --is-ancestor <sha> <branch>, where <branch> is the module's recorded branch (use HEAD only if the module has no branch)
      • If it is an ancestor and the branch moved: report "N new commits since last recorded" (git -C <repo> rev-list --count <sha>..<branch>). In the monorepo layout, N can include haren-only commits
      • If it is not an ancestor: report drift
    • The key default in lastCommit means the repo that holds the haren folder (monorepo layout) or the module's first repo (workspace layout)
    • If drift is detected: warn the user. After the user agrees, update progress.json via update-tracking skill

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.
