Paul O'Reilly b76e56f750 fix(claude-profile): use --append-system-prompt-file to avoid ARG_MAX on large projects
Passing combined context inline as a CLI arg hits Linux ARG_MAX (~2 MB)
when project CONTEXT.md or MEMORY.md are large. Three changes:

1. Write combined_context to a mktemp file and pass via
   --append-system-prompt-file instead of the inline --append-system-prompt arg.

2. Drop exec in favour of a subprocess call so the EXIT trap fires
   after claude exits, properly resetting the WezTerm theme and cleaning
   up the temp file. (With exec, bash is replaced immediately and traps
   never fire on success — WezTerm reset was silently broken.)

3. Warn when context exceeds 150 KB and show context size (in KB) on
   the launch line and in dryrun output, so oversized CONTEXT.md files
   are visible before they become a crash.

small-scripts

A collection of small, standalone utility scripts for daily use. Scripts are symlinked into ~/sbin for PATH availability.

Approach

This project uses spec-driven development (OpenSpec) as a testbed for agent-driven development and refinement:

  1. Every script starts with a spec in specs/
  2. Every script supports --dryrun to preview actions without side effects
  3. Every script has a test in tests/ that validates dryrun behaviour against the spec

semver-ci Compute MAJOR.MINOR.PATCH.BUILD from commit-message tokens, maintain VERSION.md, and (on main) tag/push/create a Gitea release — see docs/semver-ci.md and template at templates/gitea-workflow-version.yml Done
wait-for-release Poll a Gitea repo's releases until a glob pattern matches or a timeout expires (default 600s) Done

Engagement modes (claude-profile)

claude-profile launches Claude Code with both a configuration profile (selecting which ~/.claude-* directory to use) and an engagement mode that bundles a driver model, subagent policy, async tolerance, and workflow stance:

Mode Driver For
chat Haiku No project, just conversation
quick Sonnet Single small focused job, fully synchronous
deep Sonnet (Opus via named workflows) Hard design or debugging, plan + spec enforced
hybrid Haiku (Opus/Sonnet on demand) Long sessions, escalates only when needed
orch Sonnet Decompose work and dispatch container agents

Mode definitions live in data/claude-profile/modes/<name>.md — YAML frontmatter (machine-parsed) plus a markdown body that becomes part of the system prompt.

claude-profile                              # interactive picker
claude-profile oreillyit --mode deep        # explicit profile + mode
claude-profile --preset deep-cluster        # named preset from presets.yaml
claude-profile --dryrun [...]               # show resolved values, do not launch

Copy data/claude-profile/presets.yaml.example to $CLAUDE_CONFIG_DIR/presets.yaml to set up named presets.
