Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00964 |
| Opus 5 | $0.00014 | $0.00482 |
| Sonnet 5 | $0.00005 | $0.00193 |
| Haiku 4.5 | $0.00003 | $0.00096 |
Grade A, and why
initialize-pdlc-directory 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Initialize PDLC Directory
Creates the .pdlc/ directory structure in the project root (or $1 if provided) and populates it with default templates.
Already-existing files are never overwritten — safe to run on a project that has partially adopted the structure.
Prerequisites
- Apply the shared PDLC conventions in
skills/pdlc/references/shared.md. - Write access to the project root.
- The canonical templates at
../../templates/relative to this skill file (i.e.skills/pdlc/templates/).
Steps
- Determine the project root: use
$1if provided, otherwise the current working directory. - Resolve the PDLC write location per
pdlc/references/shared.md: default<project-root>/.pdlc/; if it cannot be created andPDLC_DIRis set, use$PDLC_DIR/{owner}/{repository}/.pdlc/; mirror created files when set. Record which location was used. - Create each directory below (under the resolved write location) if it does not already exist:
.pdlc/ .pdlc/context/ .pdlc/initiatives/ .pdlc/decisions/ .pdlc/learnings/ .pdlc/templates/ .pdlc/templates/initiatives/ .pdlc/templates/context/ - Create
.pdlc/.gitignore— only if it does not already exist — to keep local-only workflow state out of version control:# Local-only workflow state — do not commit # Orchestrator run state state.yml # Per-initiative progress tracking and session logs initiatives/*/progress.mdstate.ymland each initiative'sprogress.mdare regenerated per machine and per run, so they must never be committed. Theinitiatives/*/progress.mdpattern ignores only the per-initiative files, not the template. Only the repo's.pdlc/.gitignoreis meaningful; do not create one under thePDLC_DIRmirror. - For each canonical template file (read from
../../templates/relative to this skill), copy it to the corresponding path under.pdlc/templates/— only if the destination file does not already exist. The templates are the initiative artifacts (underinitiatives/), the decision and learning templates, and the context templates (undercontext/). - For each context file below, create it under
.pdlc/context/— only if it does not already exist — using the corresponding canonical template (from../../templates/context/) as starting content:product-overview.mdvision.mdgoals.mdroadmap.mdvocabulary.md
- Write the PDLC anchor to the repo's primary agent-instruction file, per
pdlc/references/shared.md(AGENTS.md PDLC anchor). This injects a short, marker-delimited## PDLCsection intoAGENTS.md(creatingAGENTS.mdif it doesn't exist). The block is idempotent: create if absent, replace its delimited content if the markers exist, never touch content outside the markers. Note the target file and whether it was created, updated, or skipped in the report. - Report what was created and what was skipped (already existed). When
PDLC_DIRis set, note whether each path was written to the repo, the mirror, or both.
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.

initialize-pdlc-directory is a skill published in the GitHub repository tomzx/agents (6 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 964 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.
